Functional Description
Our 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
