General Description

S The VSC7166 is used to interface between OC-192 Framers and Parallel Optical Modules.

In the Serializer, 16-bit OC-192 data from the Framer is mapped and encoded onto twelve 1.244 Gb/s, 8b/10b outputs, with 1 of the twelve outputs being used for XOR protection and another of the twelve for EDC.

In the Deserializer, the twelve 1.244 Gb/s www.DataSheet4U.com inputs are decoded and remapped to SFI-4 OC-192 data for Expanding use of the Internet has caused very high volumes of data traffic to become concentrated at places such as central offices (CO’s), points of presence (POP) and portal sites.
