The DTR-xxx-LC and DTR-xxx-LS fiber optic
transceivers offer a simple, convenient way to interface
PCBs to multimode fiber optic cables. They are designed
for ATM/SONET/SDH applications at OC-3/STM-1
(156 Mb/s) and OC-12/STM-4 (622 Mb/s).
The transmit and receive functions are contained in a
narrow width two-row, 10-pin (2x5) package with a
Duplex LC connector interface. The receptacle fits into
an RJ-45 form factor outline. The 10-pin configuration
is in conformance to a Small Form Factor (SFF)
multisource transceiver agreement.
The transmitter incorporates a highly reliable 1300 nm
InGaAsP surface-emitting LED and a driver circuit which
converts LV-PECL data to light. A LV-TTL Transmitter
Disable control input is also provided. The receiver
features a transimpedance amplifier IC for high sensitivity
and wide dynamic range. The Receiver Signal Detect
status output can be either LV-TTL or LV-PECL.
The transceiver operates from a single +3.3V power
supply over an operating temperature range of 0°C to
+70°C or - 40°C to +85°C (“A” option). The package is
made of either conductive plastic or metal for excellent
EMI shielding

Receiver Electrical Interface (over Operating Case Temperature Range)
Electrical Power Supply Characteristics (over Operating Case Temperature Range)
Transmitter: When the DATA+ input is at logic HIGH and
DATA- input is at logic LOW, the LED is ON; and vice versa.
The transmitter is normally enabled (i.e. when the TX
DISABLE control input is not connected). When the TX
DISABLE control input voltage is higher than VCC - 1.3 V, the
LED is turned off independent of the input data.
Receiver: Both differential DATA+ and DATA- outputs are
LV-PECL levels requiring proper termination (see
recommended interface circuits). For optimum performance,
both outputs should be terminated in the same manner, even if
only one is used.
The Signal Detect circuit monitors the level of the incoming
optical signal and generates a logic LOW signal when
insufficient photocurrent is produced. If the SIGNAL DETECT
output is LV-TTL level, no termination is required. If the
SIGNAL DETECT output is LV-PECL level, a termination
resistor of 160 ohms to GND is required.

Interface circuit: Three options for
interface circuit are shown here: two
with DC coupling and one with AC
coupling.
The power supply line should be well-
filtered. All 0.1 mF power supply
bypass capacitors should be as close
to the DTR transceiver module as
possible. The two front GND posts
(mounting studs) should be grounded
to Chassis Ground. If Chassis Ground
is not available, they should be
connected to Circuit Ground.
