B.5.1 TXP_MR_10G Card Specifications
The TXP_MR_10G card has the following specifications:
•
Caution
•
An optical device on the card keeps the laser wavelength locked as closely as possible to the ITU nominal
Note
value. The allowed drift is +/- 25 pm.

Line (trunk side)
– Bit rate:
9.95328 Gbps for OC-192/STM-64
10.70923 Gbps with ITU-T G.709 Digital Wrapper/FEC
10.3125 Gbps for 10 GE
11.095 Gbps with ITU-T G.709 Digital Wrapper/FEC over 10GE
Code: Scrambled NRZ
–
Fiber: 1550-nm single-mode
–
Maximum chromatic dispersion allowance: 1000 ps/nm
–
Loopback modes: Terminal and facility
–
You must use a 15-dB fiber attenuator (10 to 20 dB) when working with the TXP_MR_10G
card in a loopback on the trunk port. Do not use direct fiber loopbacks with the TXP_MR_10G
card. Using direct fiber loopbacks causes irreparable damage to the TXP_MR_10G card.
Connectors: LC
