For single-ended operation both DATA and DATA are internally tied to a VBB. The unused input then requires no connection or biasing. The disable function disables the laser bias and modulator. The switching threshold is VCC –3.2 V. If this input is not connected the module is enabled. This input may be connected to a CMOS HI or tied to VCC to disable. 444 LASER BIAS MONITOR REAR FACET MONITOR The module provides the necessary bias and modulation control to maintain the extinction ratio at better than 8.2 dB and the waveform is compliant with SONET/SDH Eyemask standard G.957. The laser bias control loop compensates for temperature induced variations in laser performance. The bias current monitor indicates the amount of dc current supplied to the laser. (This is approximately the laser threshold current). The rear facet monitor is a signal proportional to the laser output power. This can be used as part of a HI/LO light alarm. In the absence of data the laser will emit a mean optical power within the specified limits. The extinction ratio and duty cycle distortion are specified assuring a 50% duty cycle at the correct data rate. Performance Specifications Absolute Maximum Ratings Absolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided each limiting parameter is in isolation and all other parameters have values within the performance specification. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time.
