A.9.5 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
• 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.
