B.5.1 TXP_MR_10G Card Specifications
The TXP_MR_10G card has the following specifications:
• Line (trunk side)
– Bit rate:
9.95328 Gbps for OC-192/STM-64
10.70923 Gbps with ITU-T G.709 Digital Wrapper/forward error correction (FEC)
10.3125 Gbps for 10 Gigabit Ethernet (GE)
11.095 Gbps with ITU-T G.709 Digital Wrapper/FEC over 10 GE
– Code: Scrambled NRZ
– Fiber: 1550-nm single-mode
– Maximum chromatic dispersion allowance: 1000 ps/nm
– Loopback modes: Terminal and facility
Caution 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
– Compliance Telcordia GR-253-CORE, ITU-T G.707, ITU-T G.691
• Transmitter (trunk side)
– Maximum transmitter output power: +3.5 dBm
– Minimum transmitter output power: +2.5 dBm
– Transmitter: Lithium Niobate (LN) external modulator transmitter
– Wavelength stability (drift): +/– 25 picometers (pm)
Note An optical device on the card keeps the laser wavelength locked as closely as possible to the ITU
nominal value. The allowed drift is +/– 25 pm.
• Currently available wavelengths and versions of TXP_MR_10G (16 card versions, each covering
two wavelengths):
– 1530.33 to 1531.12 nm (two wavelengths)
– 1531.90 to 1532.68 nm (two wavelengths)
– 1534.25 to 1535.04 nm (two wavelengths)
– 1535.82 to 1536.61 nm (two wavelengths)
– 1538.19 to 1538.98 nm (two wavelengths)
– 1539.77 to 1540.56 nm (two wavelengths)
