APPLICATIONS
100G CWDM4 applications with FEC
Finisar’s FTLC1152RGPL QSFP28 transceiver modules are designed for use in 100
Gigabit Ethernet links on up to 2 km of single mode fiber. They are compliant with the
QSFP28 MSA1, CWDM4 MSA2 and portions of IEEE P802.3bm6. Digital diagnostics
functions are available via the I2C interface, as specified by the QSFP28 MSA and
Finisar Application Note AN-21535. The transceiver is RoHS-6 compliant and lead-free
per Directive 2011/65/EC4 and Finisar Application Note AN-20385.
