–
An optical device on the card keeps the laser wavelength locked as closely as possible to the ITU nominal
Note
value. The allowed drift is +/– 25 pm.
Currently available wavelengths and versions of TXP_MR_10E_L card:

A-76
You must use a 15-dB fiber attenuator (10 to 20 dB) when working with the TXP_MR_10E_L
card in a loopback on the trunk port. Do not use direct fiber loopbacks with the
TXP_MR_10E_L card. Using direct fiber loopbacks causes irreparable damage to the
TXP_MR_10E_L card.
Connectors: LC
Maximum transmitter output power: +6 dBm
Minimum transmitter output power: +2 dBm
Transmitter: LN external modulator transmitter
Wavelength stability (drift): +/– 25 picometers (pm)
