Hardware Specifications

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.

Transmitter (trunk side)

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:

ITU grid blue band:

ITU grid red band:

Receiver (trunk side)

Line (client side)

Loopback modes: Terminal and facility

Connectors: LC

Compliance: ITU-T G.707, ITU-T G.709, ITU-T G.957, and Telcordia GR-253-CORE

Maximum transmitter output power: +6 dBm
