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 minimum 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 dispersion 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.
