DESCRIPTION This data sheet describes the Siemens single mode ATM long haul transceiver. ATM is being developed to facilitate solutions in multimedia applications and real time transmission. The data rate is scalable, and the ATM protocol is the basis of the broadband public networks being standardized in the International Telecommunications Union (ITU), the former International Telegraph and Telephone Consultative Committee (CCITT). ATM can also be used in local private applications. The Siemens single mode ATM long haul transceiver is a single unit comprised of a transmitter, a receiver and an SC receptacle. It thereby frees the customer from many alignment and PC board layout concerns. The module is designed for low cost WAN applications. It can be used as the network end device interface in workstations, servers, and storage devices, and in a broad range of network devices such as bridges, routers, intelligent hubs, and wide area ATM switches. This transceiver operates at 155.520 Mbits per second from a single power supply (+5 Volt). The full differential data inputs and outputs are PECL compatible. Functional Description of 1x9 Pin Row Transceiver This transceiver is designed to transmit serial data via single mode cable. Figure 1. Functional diagram
stant output power of the laser over temperature and aging. The power control uses the output of the monitor pin diode (mechanically built in the laser coupling unit) for the controlling function to prevent the laser power from exceeding the operating limits. This module is a laser Class 1 product due to an integrated automatic shutdown circuit, which disables the laser when it detects transmitter failures. The transceiver contains a supervisory circuit to monitor the power supply. This circuit makes an internal reset signal whenever the supply voltage declines 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. Recommended Operating Conditions

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 electrical PECL compatible serial data (TD and TDnot) into optical serial data. It contains a laser driver circuit which drives the modulation and bias current of the laser diode. The currents are controlled by a power control circuit to guarantee a con-

Notes 1. Transmitter meets ANSI T1E1.2, SONET OC-3, and ITU G.957 mask patterns. 2. Minimum average optical power at which the BER is less than 1x10E-10. Measured with a 223-1 NRZ PRBS as recommended by ANSI T1E1.2, SONET OC-3, and ITU G.957 3. An increase in optical power above the specified level will cause the SIGNAL DETECT to switch from a LO state to a HI state. 4. A decrease in optical power below the specified level will cause the SIGNAL DETECT to switch from a HI state to a LO state. 5. PECL 10K compatible. Load is 50 into VCC2V. Measured under DC conditions at 25°C. For dynamic measurements a tolerance of 50 mV should be added, VCC=5V. 6. PECL compatible. A high level on this output shows that an optical signal is applied to the optical input. 7. Measured by switching the light from <40 dBm to 25 dBm. 8. Measured by switching the light from 25 dBm to <40 dBm. Switching from higher power levels increases this time. 9. Laser power is shut down if power supply is below VTH and switched on if power supply is above VTH after tRES.
module must provide power supply protection that guarantees that the system power source will cease to provide power if the maximum recommended operation limit or more is detected on the +5 V at the power source. The temperature of the module case must be in the temperature range given in the recommended operating limits. These limits guarantee the laser safety. Usage Restrictions The optical ports of the modules shall be terminated with an optical connector or with a dust plug. Note
Failure to adhere to the above restrictions could result in a modification that is considered an act of "manufacturing," and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration [ref. 21 CFR 1040.10 (i)].
