The appropriate fiber optic cable is 62.5 µm or 50 µm multimode fiber with LC™ connector. Operating range for over each optical fiber type Fiber type 62.5 micron MFF 50.0 micron MFF 10 micron SFF Minimum range (meters) 2 to 260 2 to 550 Not supported Typ. 400 700 The module is designed for low cost SAN, LAN, WAN, Fibre Channel 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, hubs, and local and wide area switches. This transceiver operates at 1 and 1.25 Gbit/s from a single power supply (+3.3 V). The full differential data inputs and outputs are PECL and LVPECL compatible. Functional Description of 2x5 Pin Row Transceiver This transceiver is designed to transmit serial data via multimode cable. Functional Diagram Automatic Shut-Down TxDis LEN TD− TD+ Laser Driver Laser Coupling Unit e/o Laser Power Control Monitor RD− RD+ SD o/e Multimode Fiber Rx Coupling Unit o/e Receiver The receiver component converts the optical serial data into PECL compatible electrical data (RD and RDnot). 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 differentially 100 Ω terminated. The transmitter contains a laser driver circuit that drives the modulation and bias current of the laser diode. 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. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects laser fault to guarantee the laser Eye Safety. 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. The laser can be disabled by the TxDis input. The Infineon Gigabit Ethernet multimode transceiver is a single unit comprised of a transmitter, a receiver, and an LC™ receptacle. This design frees the customer from many alignment and PC board layout concerns. This transceiver supports the LC™ connectorization concept. It is compatible with RJ-45 style backpanels for high end Data Com and Telecom applications while providing the advantages of fiber optic technology.
