Chapter 4 Optical Cards
4.14 OC192 LR/STM64 LH ITU 15xx.xx Card
Note Longer distances are possible in an amplified system using dispersion compensation.
Note The optics thresholds for this card are not retained after it is reset. As a result, the optics thresholds must
be configured every time this card is reset, or any time the TCC/TCC2 card is reset. See DLP-D109 in
the Cisco ONS 15454 SDH Procedure Guide, R7.0 for instructions on setting the optics thresholds.
Warning
The laser is on when the optical card is booted. The port does not have to be in service for the laser
to be on.
The card supports concatenated or nonconcatenated payloads on a VC-4 basis, as well as VC-4, VC-3,
and VC-12 payloads. Figure 4-14 shows the OC192 LR/STM64 LH ITU 15xx.xx faceplate.
