Functional Description

The 100G CFP2 LR4 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 electric-absorption modulated lasers (EMLs) with 1296, 1300, 1305, and 1309 nm center wavelengths. The optical signals are then multiplexed into a single-mode fiber through an industry-standard LC connector.On the receive side, 4 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 MDIO management interface.

Notes:

1. The supply current includes CFP2 module’s supply current and test board workingcurrent.

2. Average launch power, each lane (min) is informative for 100GBase-LR4, not the principal indicator of signal strength.

3.The receiver shall be able to tolerate , without damage, continuous exposure to an optical input signal having this average power level

4. The average receive power , each lane (max) for 100GBASE-ER4 is larger than the

100BASE-ER4 transmitter value to allow compatibility with 100BASE-LR4 units at short distances

5. Average receive power, each lane (min) is informative and not the principal indicator

of signal strength. A received power below this value cannot be compliant; however, a value above this does not ensure compliance

6. Receiver sensitivity (OMA), each lane (max) is informative

7. Measured with conformance test signal at TP3 for BER=10-12

8. conditions of stressed receiver sensitivity test: vertical eye closure penalty for each lane is 1.8dB;stressed eye J2 jitter for each lane is 0.3UI; stressed eye J9 jitter for each lane is 0.47UI.

Hardware Control Pins
