FIGURE 21 CFP2 to QSFP28 conversion module
A QSFP28 transceiver plugs into the conversion module, and a QSFP cable connects to the transceiver, as shown in the following
illustration.

100 GbE QSFP28 SR4 optics support Forward error correction (FEC). FEC enhanced data reliability by inserting redundant data, called
error correcting code, into data being transmitted or stored. You can enable or disable FEC using the fec command in interface
configuration mode.
The following example configures FEC on Ethernet interface 1/1:
device# configure terminal
device(config)# interface ethernet 1/1
device(config-if-e10000-1/1)# fec
device(config-if-e10000-1/1)# end
NOTE
100 GbE QSFP28 transceivers do not support breakout mode.
Use the following QSFP28 transceiver and optical cable for the conversion module:
• QSFP28 LR4, 2Km and 10Km transceiver
• QSFP28 SR4 transceiver
• 40GbE QSFP to QSFP cable, 10m AOC
QSFP28 form factor media must be installed in the conversion module.
The conversion module has a bicolor (green and amber) LED which functions as follows:
