16.8.5 MXP_2.5G_10E Card

Figure 16-65

(short reach/intra-office)

(intermediate range)

The MXP_2.5G_10E provides four intermediate- or short-range OC-48/STM-16 ports per card on the

client side. Both SR-1 or IR-1 optics can be supported and the ports use SFP connectors. The client

interfaces use four wavelengths in the 1310-nm, ITU 100-MHz-spaced, channel grid.

16.8.5.4 DWDM Interface

The MXP_MP_10E serves as an OTN multiplexer, transparently mapping four OC-48 channels

asynchronously to ODU1 into one 10-Gbps trunk. The DWDM trunk is tunable for transmission over

four wavelengths in the 1550-nm, ITU 100-GHz spaced channel grid.

You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the MXP_MP_10E card in a

loopback on the trunk port. Do not use direct fiber loopbacks with the MXP_MP_10E card. Using direct

fiber loopbacks causes irreparable damage to the MXP_MP_10E card.

16.8.5.5 Multiplexing Function

The muxponder is an integral part of the optically transparent ROADM network in which data payload

channels and wavelengths are processed exclusively at the optical level without electrical to optical

(E-O) conversion. The key function of MXP_MP_10E is to multiplex 4 OC-48/STM16 signals onto one

ITU-T G.709 OTU2 optical signal (DWDM transmission). The multiplexing mechanism allows the

signal to be terminated at a far-end node by another MXP_2.5G_10E card.

Optical transparency on the muxponder is configured using OTUx and ODUx OH bytes. The

ITU-T G.709 specification defines OH byte formats that are used to configure, set, and monitor frame

alignment, FEC mode, section monitoring, tandem connection monitoring, and optical transparency.
