Cisco ONS 15454 DWDM Installation and Operations Guide, R6.0
April 2006
Chapter 16 Card Reference
16.8.4 MXP_2.5G_10G Card
Note
ITU-T G.709 specifies a form of FEC that uses a “wrapper” approach. The digital wrapper lets you
transparently take in a signal on the client side, wrap a frame around it and restore it to its original form.
FEC enables longer fiber links because errors caused by the optical signal degrading with distance are
corrected.
The port can also operate at 10.70923 Gbps in ITU-T G.709 Digital Wrapper/FEC mode.
Caution
Because the transponder has no capability to look into the payload and detect circuits, an
MXP_2.5G_10G card does not display circuits under card view.
Caution
You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the MXP_2.5G_10G card in a
loopback on the trunk port. Do not use direct fiber loopbacks with the MXP_2.5G_10G card. Using
direct fiber loopbacks causes irreparable damage to the MXP_2.5G_10G card.
You can install MXP_2.5G_10G cards in Slots 1 to 6 and 12 to 17.
Caution
Do not install an MXP_2.5G_10G card in Slot 3 if you have installed a DS3/EC1-48 card in Slots 1or 2.
Likewise, do not install an MXP_2.5G_10G card in Slot 17 if you have installed a DS3/EC1-48 card in
Slots 15 or 16. If you do, the cards will interact and cause DS-3 bit errors.
You can provision this card in a linear configuration. MXP_2.5G_10G cards cannot be provisioned as a
BLSR/MS-SPRing, a path protection/SNCP, or a regenerator. They can be used in the middle of
BLSR/MS-SPRing or 1+1 spans only when the card is configured for transparent termination mode.
The MXP_2.5G_10G port features a 1550-nm laser on the trunk port and four 1310-nm lasers on the
client ports and contains five transmit and receive connector pairs (labeled) on the card faceplate. The
card uses a dual LC connector on the trunk side and SFP connectors on the client side for optical cable
termination.
