A.9.6 MXP_2.5G_10E_C Card Specifications
–
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_C card in
a loopback on the trunk port. Do not use direct fiber loopbacks with the MXP_2.5G_10E_C card. Using
direct fiber loopbacks causes irreparable damage to the 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.
• Currently available wavelengths and versions of MXP_2.5G_10E_C card:
There is a single version of the MXP_2.5G_10E_C card. It is tunable across 82 wavelengths in the
C-band frequency plan, with channels on the ITU 50-GHz grid, as shown in Table A-35.
