page 8-4.
8.8.3 Client Interfaces
The MXP_2.5G_10E_C and MXP_2.5G_10E_L cards provide four intermediate- or short-range
OC-48/STM-16 ports per card on the client side. Both SR-1 and IR-1 optics can be supported and the
ports use SFP connectors. The client interfaces use four wavelengths in the 1310-nm,
ITU 100-GHz-spaced, channel grid.
8.8.4 DWDM Interface
The MXP_2.5G_10E_C and MXP_2.5G_10E_L cards serve as OTN multiplexers, transparently
mapping four OC-48 channels asynchronously to ODU1 into one 10-Gbps trunk. For the
MXP_2.5G_10E_C card, the DWDM trunk is tunable for transmission over the entire C band and for the
MXP_2.5G_10E_L card, the DWDM trunk is tunable for transmission over the entire L band. Channels
are spaced at 50-GHz on the ITU grid.
