CSoP (Channelized SONET/SDH over Packet) Smart SFP™ converts a fully channelized SONET/SDH signal to a packet stream using RFC4553 SAToP TDM over packet pseudowire technology.

Designed in conformance with the Small Form Factor Pluggable 20-pin Multi-Source Agreement (MSA), CSoP Smart SFP™ can replace an existing SFP in a router or a switch and transport E1/DS1 traffic across a packet network. CSoP Smart SFP™ aggregates single E1/DS1 or low fill SONET/SDH links and enables each E1 or DS1 channel to be processed individually to provide a high density Gateway between a SONET/SDH network and a TDM over packet ethernet or IP/MPLS network.

The integration of CSoP into an SFP greatly reduces system and network complexity, and offers lower carbon footprint while generating CAPEX and OPEX savings. CSoP capabilities are complemented with a Gigabit Ethernet system interface. The Smart SFP™ serves a wide range of optical and reach applications: OC-3/STM-1 duplex fiber with reaches up to 80 km at industrial temperature range.

Optionally, an API and SNMP MIBs are available to facilitate the integration in existing equipment and management systems. This management interface allows for configuration and monitoring of relevant parameters.
