A.9.2    MXP_2.5G_10G Card Specifications
 –
Bit rate: 
9.95328 Gbps for OC-192/STM-64 
10.70923 Gbps with ITU-T G.709 Digital Wrapper/FEC
 –
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 20-dB fiber attenuator (15 to 25 dB) when working with the MXP_2.5G_10G 
card in a loopback on the trunk port. Do not use direct fiber loopbacks with the 
MXP_2.5G_10G card. Using direct fiber loopbacks causes irreparable damage to the 
MXP_2.5G_10G card.
 –
Connectors: LC 
 • Transmitter (trunk side) 
 –
Maximum transmitter output power: +3.5 dBm 
 –
Minimum transmitter output power: +2.5 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.
