Ethernet Line Cards and MPAs
The following tables list the Cisco ASR 9000 Series Ethernet line cards and MPAs (Modular Port Adapters)
and their corresponding Cisco product identification numbers (PIDs), organized by generation.
RS-FEC are a group of error-correcting codes that are widely used in mass storage systems to correct the burst
errors associated with media defects. All the line cards and MPAs that support OTN mode support RS-FEC.
In the LAN mode, SR4, CWDM4, and PSM4 optics are enabled with RS-FEC by default (as per IEEE
Standard).
