4.14 OC192 LR/STM64 LH ITU 15xx.xx Card
Sixteen distinct STM-64 ITU 100 GHz DWDM cards comprise the ONS 15454 SDH DWDM channel
plan. The OC192 LR/STM64 LH ITU 15xx.xx card provides one long-range SDH STM-64 port per card,
compliant with ITU-T G.707 and G.957, and Telcordia GR-253-CORE (except minimu m and maximum
transmit power, and minimum receive power). The port operates at 9.95328 Gbps over unamplified
distances up to 60 km with different types of fiber such as C-SMF or d ispersion compensated fiber
limited by loss and/or dispersion.
Note Longer distances are possible in an amplified system using dispersion compensation.
The card supports concatenated or nonconcatenated payloads on a VC-4 basis, as well as VC-4, VC-3,
and VC-12 payloads. Figure 4-23 shows the OC192 LR/STM64 LH ITU 15xx.xx faceplate.
