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. If no optical input signal is present, the receiver data outputs are switched to static low level (RD=Low, RDnot=High). The transmitter converts electrical PECL compatible serial data (TD and TDnot) into optical serial data. It 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 in 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 transmitter failures. A reset is only possible by turning the power off, and then on again.

Notes 1. Minimum average power at which the BER is less than 2.5E-10 or lower. Measured with the ANSI Worst Case pattern from Appendix 5 of the PMD. 2. An increase in optical power above the specified level will cause the SIGNAL DETECT to change from Low to High. 3. A decrease in optical power below the specified level will cause the SIGNAL DETECT to change from High to Low. 4. PECL compatible. Load is 50 into VCC-2 V. Measured under DC conditions. For dynamic measurements a tolerance of 50 mV should be added. VCC=5 V. 5. PECL compatible. A high level on this output shows that an optical signal is applied to the optical input. 6.

LASER SAFETY This single mode FDDI transceiver is a Class 1 laser product. It complies with IEC 825-1 and FDA 21 CFR 1040.10 and 1040.11. The transceiver must be operated under recommended operating conditions. Caution The use of optical instruments with this product will increase eye hazard! General Restrictions Classification is valid only if the module is operated within the specified temperature and voltage limits. The system using the 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 operating temperature of the module 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)).
