5.1.3 Interface Classes
Table 5-4 lists the optical performance parameters for 10-Gbps cards that provide signal input to
multiplexer and demultiplexer cards.
C OC-192 LR ITU cards (TXP_MR_10E, TXP_MR_10E_C, and TXP_MR_10E_L)
without FEC
D 2.5-Gbps multirate transponder card (TXP_MR_2.5G), both protected and
unprotected, with FEC enabled
E OC-48 100-GHz DWDM muxponder card (MXP_MR_2.5G) and 2.5-Gbps
multirate transponder card (TXP_MR_2.5G), protected or unprotected, with FEC
disabled and retime, reshape, and regenerate (3R) mode enabled
F 2.5-Gbps multirate transponder card (TXP_MR_2.5G), protected or unprotected,
in regenerate and reshape (2R) mode
G OC-48 ELR 100 GHz card
H 2/4 port GbE transponder (GBIC WDM 100GHz)
I TXP_MR_10E, TXP_MR_10E_C, and TXP_MR_10E_L cards with enhanced
FEC (E-FEC) and the MXP_2.5G_10E, MXP_2.5G_10E_C, MXP_2.5G_10E_L,
MXP_MR_10DME_C, and MXP_MR_10DME_L cards with E-FEC enabled
