Transmitter consists of 4 lasers operating at 10.3Gb/s each. 2. Minimum value is informative. 3. Even if TDP < 0.5 dB (MMF) or TDP < 0.8 dB (SMF), TxP - TDP must be geater than this value. 4. RIN is scaled by 10*log(10/4) to maintain SNR outside of transmitter. 5. Receiver consists of 4 photodetectors operating at 10.3Gb/s each. 6. Minimum value is informative, equals min TxOMA with infinite ER and max channel insertion loss. 7. SMF receiver sensitivity guaranteed by design, but nots measured in production. 8.

Please see Finisar Application Note AN-21046 for memory map details. Although this module is designed for both multimode and single mode fiber operation, the Tx and Rx power monitors are calibrated for multimode fiber. Therefore, the DDM reading should be relied upon only for multimode operation. VII.
