loopback on the trunk port. Do not use direct fiber loopbacks with the TXP_MR_10E card. Using direct
fiber loopbacks causes irreparable damage to the TXP_MR_10E card.
8.4.3 Client Interface
The client interface is implemented with a separately orderable XFP module. The module is a tri-rate
transceiver, providing a single port that can be configured in the field to support an OC-192 SR-1
(Telcordia GR-253-CORE) or STM-64 I-64.1 (ITU-T G.691) optical interface, as well as 10GE LAN
PHY (10GBASE-LR), 10GE WAN PHY (10GBASE-LW), or 10G FC signals.
The client side XFP pluggable module supports LC connectors and is equipped with a 1310-nm laser.
8.4.4 DWDM Trunk Interface
On the trunk side, the TXP_MR_10E card provides a 10-Gbps STM-64/OC-192 interface. There are four
tunable channels available in the 1550-nm band or eight tunable channels available in the 1580-nm band
on the 50-GHz ITU grid for the DWDM interface. The TXP_MR_10E card provides 3R (retime, reshape,
