Finisar’s FTL4C3QE1C QSFP+ transceiver modules are designed for use in 40 Gigabit
Ethernet links over duplex multimode or single mode fiber. They are compliant with the
QSFP+ MSA
1,2
and represent a multimode adaptation of IEEE 802.3ba 40GBASE-LR4
3
refered to as LM4. Digital diagnostics functions are available via an I2C interface, as
specified by the QSFP+ MSA. The optical transceiver is compliant per the RoHS Directive
2011/65/EU
