For information on safety labels for the cards, see the “8.2.2 Class 1M Laser Product Cards” section on
page 8-6.
Caution You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the cards in a loopback on the
trunk port. Do not use direct fiber loopbacks with the cards. Using direct fiber loopbacks causes
irreparable damage to the MXP_MR_10DME_C and MXP_MR_10DME_L cards.
8.10.3 Wavelength Identification
The card uses trunk lasers that are wavelocked, which allows the trunk transmitter to operate on the ITU
grid effectively. Both the MXP_MR_10DME_C and MXP_MR_10DME_L cards implement the UT2
module. The MXP_MR_10DME_C card uses a C-band version of the UT2 and the
MXP_MR_10DME_L card uses an L-band version.
