The appropriate fiber optic cable is 62.5 m or 50 m multimode fiber with duplex SC connector. The Siemens Gigabit Ethernet multimode transceiver is a single unit comprised of a transmitter, a receiver, and an SC receptacle. This design frees the customer from many alignment and PC board layout concerns. The module is designed for low cost LAN, WAN, and Gigabit Ethernet applications. It can be used as the network end device interface in mainframes, workstations, servers, and storage devices, and in a broad range of network devices such as bridges, routers, intelligent hubs, and local and wide area switches. JUNE 1998 This transceiver operates at 1.3 Gbits per second from a single power supply (+5 V or +3.3 V). The full differential data inputs and outputs are PECL compatible. TECHNICAL DATA The electro-optical characteristics described in the following tables are valid only for use under the recommended operating conditions.

Data inputs are AC coupled with 100 differential termination built into the transceiver. o/e Transmitter Electro-Optical Characteristics The receiver component converts the optical serial data into PECL compatible electrical data (RD and RDnot) which are AC coupled with a biasing build into the transceiver. The Signal Detect (SD, active high) shows whether an optical signal is present. The transmitter converts PECL compatible electrical serial data (TD and TDnot) into optical serial data. Data lines are AC coupled with differential 100 termination. Transmitter Symbol Min.

The currents are controlled by a power control circuit to guarantee constant output power of the laser over temperature and aging. The power control uses the output of the monitor PIN diode (mechanically built into the laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the operating limits.

Into multimode fiber, 62.5 m or 50 m diameter. 2. Laser power is shut down if power supply is below VTH and switched on if power supply is above VTH after tRES. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. A reset is only possible by turning the power off, and then on again. The transceiver contains a supervisory circuit to control the power supply. This circuit makes an internal reset signal whenever the supply voltage drops below the reset threshold. It keeps the reset signal active for at least 140 milliseconds after the voltage has risen above the reset threshold. During this time the laser is inactive.
