Functional Description
●OLSQXXTXM-CD02 optical transceiver integrates the transmit and receive path onto one module.
●On the transmit side, four lanes of serial data streams are recovered, retimed,and passed on to four laser drivers, which control four CWDM with ●1271, 1291, 1311, and 1331 nm center wavelengths.
●The optical signals are then multiplexed into a single-mode fiber through an industry-standard LC connector.
●On the receive side, four lanes of optical data streams are optically demultiplexed by an integrated optical demultiplexer.
●Each data steam is recovered by a PIN photodetector and transimpedance amplifier, retimed, and passed on to an output driver.
●This module features a hot-pluggable electrical interface, low power consumption, and 2-wire serial interface.

Notes:
1. Transmitter consists of 4 lasers operating at 25.78Gb/s each.
2. Average launch power, each lane (min) is informative and not the principal indicator of signal strength. A transmitter with launch power below this value cannot be compliant; however, a value above this does not ensure compliance.
3. Hit ratio 5x10-5.
4. Receiver consists of 4 photodetectors operating at 25.78Gb/s each.
5. Minimum value is informative, equals min TxOMA with infinite ER and max channel insertion loss.
6. Sensitivity is specified at 5x10-5 BER
7. Measured with CWDM4 MSA2 conformance test signal at TP3 for 5x10-5 BER
