Chapter 4 Optical Cards
4.17 4.17 OC192 LR/STM64 LH ITU 15xx.xx Card
Sixteen distinct OC-192/STM-64 ITU 100 GHz DWDM cards comprise the ONS 15454 DWDM channel
plan. Each OC192 LR/STM64 LH ITU 15xx.xx card provides one long-reach STM-64/OC-192 port per
card, compliant with ITU-T G.707, ITU-T G.957, and Telcordia GR-253-CORE (except minimum and
maximum transmit power, and minimum receive power). The port operates at 9.95328 Gbps over
unamplified distances up to 60 km (37 miles) with different types of fiber such as C-SMF or dispersion
compensated fiber limited by loss and/or dispersion.
Note Longer distances are possible in an amplified system using dispersion compensation.
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.
Statement 293
The card supports VT, nonconcatenated (STS-1), or concatenated payloads. Figure 4-19 shows the
OC192 LR/STM64 LH ITU 15xx.xx faceplate.
