A.9.12 TXP_MR_10E_L Card Specifications
Caution 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
• Transmitter (trunk side)
– Maximum transmitter output power: +6 dBm
– Minimum transmitter output power: +2 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 TXP_MR_10E_L card:
There is a single version of the TXP_MR_10E_L card. It is tunable across 80 wavelengths in the
L band frequency plan, with channels on the ITU 50-GHz grid, as shown in Table A-44.
