 OTU3, OTU3e1, OTU3e

Finisar’s FTL4E1QM1C QSFP+ transceiver modules are designed for use in 40 Gigabit

Ethernet links and 4x10G OTN client interfaces over single mode fiber. They are compliant

with the QSFP+ MSA1

, IEEE 802.3bm 40GBASE-ER42

and OTU3 requirements specified

in ITU-T Recommendation G.6953

as adapated to a 40km interface. 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/EU5

. See Finisar Application Note
