TXP_MR_10E_C and TXP_MR_10E_L Card Description
Client and Trunk Ports
The TXP_MR_10E card features a universal transponder 2 (UT2) 1550-nm tunable laser (C band) or a
UT2 1580-nm tunable laser (L band) for the trunk port and a separately orderable ONS-XC-10G-S1
1310-nm laser XFP module for the client port. On its faceplate, the TXP_MR_10E_C and
TXP_MR_10E_L cards contain two transmit and receive connector pairs, one for the trunk port and one
for the client port. Each connector pair is labeled.

DWDM Trunk Interface
On the trunk side, the TXP_MR_10E_C and TXP_MR_10E_L cards provide a 10-Gbps
STM-64/OC-192 interface. There are 80 tunable channels available in the 1550-nm C band or 82 tunable
channels available in the 1580-nm L band on the 50-GHz ITU grid for the DWDM interface. The
TXP_MR_10E_C and TXP_MR_10E_C cards provide 3R transponder functionality for this 10-Gbps
trunk interface. Therefore, the card is suited for use in long-range amplified systems. The DWDM
interface is compliant with ITU-T G.707, ITU-T G.709, and Telcordia GR-253-CORE standards.

The DWDM trunk port operates at a rate that is dependent on the input signal and the presence or absence
of the ITU-T G.709 Digital Wrapper/FEC. The possible trunk rates are:
of the ITU-T G.709 Digital Wrapper/FEC. The possible trunk rates are:
•
OC192 (9.95328 Gbps)
•
OTU2 (10.70923 Gbps)
•
10GE (10.3125 Gbps) or 10GE into OTU2 (nonstandard 10.0957 Gbps)
•
10G-FC (10.51875 Gbps) or 10G-FC into OTU2 (nonstandard 11.31764 Gbps)
The maximum system reach in filterless applications without the use of optical amplification or
regenerators is nominally rated at 23 dB over C-SMF fiber. This rating is not a product specification, but
is given for informational purposes. It is subject to change.

Client-to-Trunk Mapping
The TXP_MR_10E_C and TXP_MR_10E_L cards can perform ODU2-to-OCh mapping, which allows
operators to provision data payloads in a standard way across 10-Gbps optical links.

Digital wrappers that define client side interfaces are called ODU2 entities in ITU-T G.709. Digital
wrappers that define trunk side interfaces are called OCh in ITU-T G.709. ODU2 digital wrappers can
include G-MPLS signaling extensions to ITU-T G.709 (such as LSP and G-PID values) to define client
interfaces and payload protocols.
