B.5.5 MXP_2.5G_10E Card Specifications
The MXP_2.5G_10E card has the following specifications:
• Line (trunk side)
– Bit rate: 10.70923 Gbps (in ITU-T G.709 Digital Wrapper/FEC mode)
– Code: Scrambled NRZ
– Fiber: 1550-nm single-mode
– Maximum chromatic dispersion allowance: +/– 1200 ps/nm (specified penalty)
– Loopback modes: Terminal and facility
Caution You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the MXP_2.5G_10E card in a
loopback on the trunk port. Do not use direct fiber loopbacks with the MXP_2.5G_10E card. Using
direct fiber loopbacks causes irreparable damage to the MXP_2.5G_10E card.
– Connectors: LC
– Compliance: ITU-T G.707, ITU-T G.709, ITU-T G.957, and Telcordia GR-253-CORE
• Transmitter (trunk side)
– Maximum transmitter output power: +6 dBm
– Minimum transmitter output power: +3 dBm
– Transmitter: 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 MXP_2.5G_10E (eight card versions):
ITU grid blue band:
– 1530.33 to 1533.07 nm (four channels)
– 1534.25 to 1537.00 nm (four channels)
– 1538.19 to 1540.95 nm (four channels)
– 1542.14 to 1544.92 nm (four channels)
ITU grid red band:
– 1546.12 to 1548.92 nm (four channels)
