•
Caution
•
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.

You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the
MXP_MR_10DME_C card in a loopback on the trunk port. Do not use direct fiber loopbacks
with the MXP_MR_10DME_C cards. Using direct fiber loopbacks causes irreparable damage
to the MXP_MR_10DME_C cards.
