4.11 OC192 SR/STM64 IO 1310 Card
Note For specifications, see the A.6.10 OC192 SR/STM64 IO 1310 Card Specifications” section on
page A-37.
The OC192 SR/STM64 IO 1310 card provides one intra-office haul, ITU-T G.707- and
G.957-compliant, SDH STM-64 port per card in the 1310-nm wavelength range. The port operates at
9.95328 Gbps over unamplified distances up to 2 km (1.24 miles). The card supports concatenated or
nonconcatenated payloads on a VC-4 basis, as well as VC-4, VC-3, and VC-12 payloads. Figure 4-10
shows the OC192 SR/STM64 IO 1310 faceplate and block diagram.
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.
