16.1.7 Multiplexer, Demultiplexer, and OADM Card Interface Classes
10-Gbps cards that provide signal input to OADM cards have the optical performance parameters listed 
in Table 16-4. 2.5-Gbps card interface performance parameters are listed in Table 16-5 on page 16-8.
E 2.5-Gbps multirate transponder (TXP_MR_2.5G), both protected and 
unprotected, with FEC disabled and reshape, regenerate, and retime (3R) mode 
enabled, or OC-48 100-GHz DWDM muxponder (MXP_MR_2.5G)
F 2.5-Gbps multirate transponder (TXP_MR_2.5G), both protected and 
unprotected, in regenerate and reshape (2R) mode
G OC-48 ELR 100 GHz
H 2/4 port GbE transponder (GBIC WDM 100GHz)
I TXP_MR_10E with extended FEC (E-FEC) or MXP_2.5G_10E with E-FEC 
enabled
