functions, including Tx/Rx power
monitoring
RoHS-6 compliant
40G Ethernet over MMF
Finisar’s FTL4C2QE1C QSFP+ transceiver modules are designed for use in 40 Gigabit
Ethernet links over duplex multimode fiber. They are compliant with the QSFP+ MSA1,2
and represent a multimode adaptation of IEEE 802.3ba 40GBASE-LR43 refered to as LM4.
Digital diagnostics functions are available via an I2C interface, as specified by the QSFP+
MSA. The transceiver is RoHS compliant per Directive 2011/65/EU4 and Finisar
Application Note AN-20385.

Notes :
1. Transmitter consists of 4 lasers operating at 10.3Gb/s each.
2. Minimum value is informative.
3. RIN is scaled by 10*log(10/4) to maintain SNR outside of transmitter.
4. Receiver consists of 4 photodetectors operating at 10.3Gb/s each.
5. Minimum value is informative, equals min TxOMA with infinite ER and max channel insertion loss.
