Data Rate, NRZ, Mark Ratio 50% PRBS= The Maximum bit error ratio for this application code of 1E-12 is only after error correction has been applied. The BER optical input specified as Minimum equivalent sensitivity can therefore be 1.8E-4 without error connection. 3. Two sets of specifications are defined depending on ER of input optical waveforms, the left set for ER between 4dB and 7dB and the right set for ER of 7dB or higher. Mechanical Dimensions Handling Precautions CAUTION: Take proper electrostatic-discharge (ESD) precautions while handling these devices. These devices are sensititive to ESD. The module meets ESD requirements given in EN , criterion B test specification when installed in a properly grounded case and chassis. The module high speed signal contacts shall withstand 1000 V electrostatic discharge based on human Body model per JEDEC JESD22-A114-b.

5 Laser Safety This product is complied with IEC as Class 1 and with FDA 21 CFR as Class I laser product. Because of size constraints, laser safety labeling is not affixed to the module but is attached to the outside of the shipping box.
