TOSLINK™ is a family of data transmission devices that use optical signals

instead of electrical signals. Because TOSLINK uses an optical fiber cable as

a transmission line, it provides the following benefits, compared to electrical

transmission using a twisted-pair or coaxial cable:

■ The transmission line (i.e. the optical cable) is not susceptible to

electromagnetic interference.

■ The optical cable does not radiate any electromagnetic noise.

■ The optical cable provides a complete galvanic isolation between

equipments.

Comparison of TOSLINK devices and photocouplers

A photocoupler is a semiconductor that consists of a light-emitting device

and a light-receiving device molded in one package. It is used to provide

electrical isolation between input and output. In contrast, TOSLINK uses

separate light-emitting and light-receiving units that are connected through

a long optical cable.

Because an optical cable is used as a transmission line, it is possible to

transmit signals over long distances while providing a galvanic isolation

between the transmitting and receiving ends.

Thus, TOSLINK can be viewed, in a sense, as a long-distance

photocoupler.

Electrical and optical transmission systems

In an electrical data transmission system, a line driver is used to drive

electrical signals through a long transmission line such as a twisted-pair

cable. At the other end, a line receiver compensates for signal decay by

amplifying the signals. A connector is required at each end of the cable.

By contrast, in a TOSLINK-based system, a transmitting module converts

electrical signals into optical signals, and a receiving module converts

optical signals back to electrical signals. An optical fiber cable is used as a

transmission line, and optical connectors link the transmitting and

receiving modules to the cable.

The TOSLINK transmitting module incorporates a light-emitting diode and

driver circuit. The TOSLINK receiving module incorporates a photodiode

and waveform reshaping circuit. The interface is either TTL or PECL for

both modules for easy connection with other peripheral ICs.

Transmitting IC

An optical fiber consists of a core surrounded by a cladding. An optical ray

entering the fiber is reflected back at the boundary between the core and

the cladding. In this manner, it travels along the length of the fiber.

There are three kinds of optical fiber:

a) All-plastic fiber (APF)

b) Plastic-clad silica fiber (PCF)

c) Silica fiber

All-plastic fiber, having a plastic core and plastic cladding, is used for

short-distance transmission. A plastic-clad silica fiber, which consists of a

silica core and plastic cladding, is used for mid-distance transmission. Silica

fiber consists of a pure silica core with silica cladding and is used for

long-distance transmission. Each optical fiber has a lower transmission loss

over a certain wavelength range and is used together with appropriate optical

modules.

Optical transmission module

The LED is driven by a differential circuit to reduce current transients

generated during the on-off switching of the LED so that the LED’s

switching does not affect peripheral ICs.

Optical receiving module

The receiving module employs an ATC (automatic threshold control) circuit

to reshape the waveform. The ATC circuit controls the comparator

reference voltage so that it is always automatically adjusted in accordance

with the input optical power. This minimizes pulse width distortion,

regardless of the length or bending of the optical fiber.

There are two package types available for TOSLINK optical modules. One

is a molded resin package for ordinary applications. The other is ceramic,

used for applications requiring exceptionally high reliability.

The structures of these two packages are shown in the figure on the right.

In the molded resin package, devices are mounted on a leadframe and

molded with transparent resin. In the ceramic package, devices are

mounted on a ceramic substrate and hermetically sealed by a metal shell.

The ceramic package provides better resistance against humidity and

temperature than the molded resin package.

Dynamic ranges of general-purpose TOSLINK modules

Toshiba defines general-purpose optical modules as those having a

data rate of up to 6 Mb/s (NRZ) over distances up to 40 m (APF).

General-purpose optical modules come in two versions: simplex

types compatible with F05 connectors and duplex types compatible

with F07 connectors. All general-purpose optical modules are

housed in molded resin packages.

Whereas the 170 Series requires the external resistor value to be

adjusted according to the transmission distance, the 190 Series

needs no such adjustment.

The figure at right illustrates the dynamic ranges of the 170 and 190

Series. The 190 Series offers a dynamic range more than 6 dB wider

than the 170 Series.

Application circuits

Application circuits for the TOTX197A(F) and TORX196(F), a pair of

transmitting and receiving modules, are shown in the figure on the right.

The TOTX197A(F) transmission module requires an external resistor to

supply current to the LED.

The TORX196(F) receiving module requires an inductor-capacitor noise

filter on the Vcc line. The module case is made of conductive resin to

provide a shielding effect against external noise. Pins #5 and #6 must be

connected to the system ground.

There are also duplex modules in the general-purpose TOSLINK series;

their application circuits are generally the same as for simplex modules.

All the general-purpose modules have a TTL interface for easy connection

with peripheral digital ICs.

Toshiba also offers a general-purpose receiving module with not only a

digital output but also an analog output. This receiving module, designated

the TORX198(F), provides an analog voltage from the internal amplifier,

which changes with the optical power input into the receiving module.

Hence, by monitoring the analog output it is possible to measure optical

power without dedicated optical power meter.

Incorporating such a feature in your system helps to simplify optical power

measurements for regular system maintenance.

When optical flux monitoring is not required, the TORX198(F) handles

digital data transmission like the other TOSLINK receiving modules. In this

case, the analog output pin may be left open.

Transceiver module for PN connectors—TODX283(F)

Toshiba offers several TOSLINK modules housed in ceramic packages that have higher reliability than plastic molded

packages.

In ceramic packages, devices are mounted on a ceramic substrate and hermetically sealed in metal shells.

Ceramic packages provide superior moisture resistance and also reduce the stress put on the internal LED, leading to

longer life.

The figure on the right illustrates the structure of the optical transceiver

module housed in a ceramic package.

The transmitter section consists of an LED, a transmitting IC that drives

the LED, and a chip capacitor mounted on a ceramic substrate.

The receiver section consists of a photodiode, a receiving IC (which

contain a waveform-reshaping circuit) and chip capacitors mounted on the

same ceramic substrate.

Both the transmitter and receiver sections are hermetically sealed in metal

shells with glass windows.

The transceiver module is installed in a case to be attached to an optical

connector and fastended from the back of the case.

The TODX283(F) transceiver, housed in a ceramic package, can be used

with either an APF (all-plastic fiber) or a PCF (plastic-clad silica fiber) cable.

Like general-purpose optical modules, the TODX283(F) incorporates a

transmitting IC that drives an LED, and a receiving IC containing a

waveform-reshaping circuit. The interface is TTL, facilitating easy

connection with peripheral ICs.

The TODX283(F) is compatible with PN and JIS F7 fiber-optics connectors.

SMI optical transceiver module—TODX2402(F)

Toshiba offers high-speed optical modules compatible with JIS F05 and SMA connectors for simplex data transmission and

those compatible with SMI (Small Multimedia Interface) and PN (Premises Network) connectors for duplex data

communication.

JIS F05 and SMA connectors have been widely used in industrial applications.

SMI connectors are suitable for digital home appliances. While SMI connectors are very small, about the same size as

digital audio simplex connectors, they provide high-speed, full-duplex data transmission.

PN connectors are an improvement over JIS F07 connectors that have been widely used in industrial applications.

The TODX2402(F) optical transceiver module is compatible with SMI

connectors that have been proposed as an industry standard for digital home

appliance applications.

The TODX2402(F) provides full-duplex 250 Mb/s transmission; thus it supports

IEEE 1394 S100 (125 Mb/s), IEEE 1394 S200 (250 Mb/s) and Fast Ethernet

(125 Mb/s).

A high-speed AV network can be built by using the TODX2402(F) in combination with an IEEE 1394b PHY layer IC. An example

is shown below.

Optical Fibers and Connector Makers List

Recommended Optical Fibers with Optical Connectors

2. Soldering

In an optical module that has been in use for some time, nearly all of the deterioration in characteristics is due to a reduction in the

fiber-output power (Pf). This is due to deterioration over time in the level of optical output of the LED used as the light source.

The drop in the LED’s optical output is thought to be caused by crystal flaws in the wafer or stress in the mold resin, although the

detailed causes are not clear.

Although LEDs used for optical communications are generally considered to have an almost infinite lifetime, their optical output does fall

over time.

The life of light-emitting devices is greatly affected by the operating conditions and operating environment as well as by the lifespan

characteristics of the particular device.Toshiba recommends that the user first check a device’s lifetime characteristics before selecting it

and setting its operating conditions.

For information on reliability, contact a Toshiba sales office. Regular maintenance, such as a check on the amount of light emitted, is

recommended.

Optical modules use semiconductor devices but are essentially optical components. When soldering, ensure that flux does not adhere

to the light-emitting or light-receiving surfaces.

Take the same care when cleaning off flux after soldering.

Some optical modules include a protective cap. This cap is intended to prevent accidental operation when the module is not in use. It is

not dust- or waterproof. Because the optical module is an optical component, Toshiba does not recommend soldering methods or

post-solder flux cleaning methods in case where flux could affect the module. Toshiba recommends first soldering without mounting the

module, then cleaning the PCB. The module should then be hand-soldered and no subsequent cleaning should be performed.

If it is not possible to hand-solder the module, one way of avoiding the effects of flux is to use non-halogen (chlorine-free) flux, taking

care not to leave chlorine or other residue, and omitting the post-solder cleaning. In such cases too, the reliability of the device must be

checked. Be sure to check the reliability of the device.

The case for the TOSLINK (simplex) optical receiving module and (duplex) optical transceiver module is made of conductive

plastic.

The case is designed to provide shielding against noise when the reinforcing pin at the front of the module is grounded. When the

module is used, this pin should be connected to the signal ground.

Since the case for the optical receiving module and optical transceiver module has a resistance of several tens of ohms, ensure that the

case does not touch the power line or any other circuits.

Generally, the use of optical transmission devices is considered to improve noise resistance.

While optical fibers are certainly not affected by noise, optical modules, particularly receiver modules, are comparatively easily affected

by noise because they handle such minute current signals.

To improve noise resistance, the TOSLINK case is treated to make it conductive. However, since the signal output from the optical

receiving modules photodiode is a minute current signal, in some environments simply shielding the case will not protect against noise.

When using a TOSLINK device, conduct live tests to check noise resistance.

A simple noise filter is mandatory for the power lines for the TOSLINK optical receiving module and optical transceiver module.

However, in the case of significant power supply ripples, further filter reinforcement is also necessary. In addition, when the optical

module is placed in a location susceptible to emission noise, Toshiba recommends covering the optical module and power supply filter

with a metal cover to enhance the shielding.

When the optical module is not in use, cover it with the protective cap.

Take particular care with the optical receiving module since, depending on the circuit used, extraneous light may be input to the module

when the TOSLINK device is not in use and may adversely affect other circuits.

Plastic-molded optical modules are plastic-sealed devices whose wires are fixed with resin. While this structure makes them

comparatively resistant to vibration and shock, wire breakage has been observed in equipment in which the soldering and connections

are exposed to vibration, shock or stress. Therefore, when using a plastic-molded optical module in equipment with high vibration levels,

ensure that the structure is designed to withstand vibration, shock and stress.

Ceramic-package optical modules are ceramic-sealed, with a hollow interior. Since the wires in the module are not fixed, the module is

susceptible to vibration and shock.

Therefore, when using a ceramic-package optical module in equipment which is subject to high levels of vibration and shock, ensure

that the structure of the equipment is designed to withstand vibration, shock and stress.

Modules should be used with a supply voltage within the standard operating conditions. Ensure that the supply voltage does not exceed

the absolute maximum ratings even momentarily.

Precautions for Using TOSLINK

12. Operating Ranges

If a voltage exceeding the absolute maximum rating is applied to the transmitter input, the internal IC may be adversely affected or

destroyed. If there is a possibility of excessive input voltage due to a surge, for example, add a protective circuit to the input.

Note that internal ICs can be damaged when the receiver output is low and the output is shorted to the power supply, or when output is

high and is shorted to GND.

Do not drop heavy or sharp metal objects onto the optical fiber cable. If the fiber cable breaks, data cannot be transmitted.

Also, transmission loss increases with sharp bends in the fiber cable. Toshiba recommends that, if the cable must be bent during

installation, the bent section should have as large a radius as possible (six to ten times the minimum bending radius).

Some fiber-optic connectors are vertical connectors. When inserting a fiber-optic connector, note the directionality of the connection.

When coupling or decoupling a fiber optic connector, be sure to hold the connector itself. Do not detach a fiber-optic connector by

pulling on the optical-fiber cord.

Since specialized assembly tools are available for the fiber-optic connectors used with TOSLINK devices, people without specialist

knowledge can assemble the connectors.

However, the person who assembled the product is responsible for its characteristics and quality.

When a connector is to be used in an application where reliability is essential, Toshiba recommends purchasing a pre-assembled

product or contacting a specialist with the necessary expertise.

The absolute maximum ratings must never be exceeded, even momentarily. Even a single rating value must never be exceeded. The

nature of the absolute maximum ratings depend on the product but generally include such parameters as the input and output currents,

input voltage, storage temperature, operating temperature and lead temperature.

If the input current or voltage exceeds the absolute maximum rating value, overvoltage and overcurrent can adversely affect the internal

circuitry of the device. If the rating is grossly exceeded, the wiring may fuse due to heating in the internal circuits, or the circuitry in the

semiconductor chips may be destroyed.

If, for example, the absolute maximum operating temperature, storage temperature or soldering temperature rating is exceeded, the

differences in the coefficients of thermal expansion of the various materials that make up the device can damage the sealing or open up

bonded parts. When using TOSLINK devices, never exceed any of the absolute maximum ratings.

The operating range is the range of conditions necessary for the device to operate as specified in individual technical datasheets and

databooks. Even if a device is operated within the absolute maximum ratings, functional operation of the device or the specifications

related to electrical or optical characteristics may not be guaranteed beyond the conditions indicated under “Operating Ranges.”

Exposure to conditions in excess of these ranges may also affect device reliability. Thus, special precautions are necessary in designing

electronic systems. For higher reliability, operating ranges should be derated for current, power and temperature.

Since optical modules, connectors and fiber cables are flammable, scorching or burning them may cause them to emit smoke or burst into

flame, which can in turn cause gas emissions. Therefore, do not use these devices in the vicinity of flames, smoke or any flammable materials.

TOSLINK devices and packaging materials must be disposed of by the user as industrial waste products in an environmentally

appropriate way and in accordance with the law.
