APPLICATIONS
100G CWDM4 Lite w/FEC
Finisar’s FTLC1152RGPL6 QSFP28 Lite reach and limited temperature transceiver
modules are designed for use in 100 Gigabit Ethernet links on up to 500m of single mode
fiber. They are compliant with the QSFP28 MSA
1
and represent a Lite version of the
CWDM4 MSA
2
(500m reach, 15°C to +60°C limited temperature), and portions of IEEE
P802.3bm
7
. Digital diagnostic functions are available via the I2C interface, as specified
by the QSFP28 MSA and Finisar Application Notes AN-2153
5
and AN-2154
6
. The
transceiver is RoHS-6 compliant and lead-free per Directive 2011/65/EC
3
and Finisar
Application Note AN-2038
