Electrical SFP transceiver interchangeable with optical modules

Designed to comply with the Small Form Factor Pluggable (SFP) industry-standard multi-source agreement (MSA), the new SFP-155E electrical transceiver from ITT Industries, Cannon delivers full duplex STM-1 electrical (155 Mbit/s) SDH transport over coaxial cables. The hot pluggable module is also fully interchangeable with STM-1 optical SFP modules.

Any system that already supports STM-1 optical can now support STM-1 electrical by using the SFP-155E. The company says a single card can now support both optical and electrical STM-1 interfaces to reduce system capital and operating costs. Typical applications include next generation SDH add/drop multiplexers, optical edge devices, MSPP and switching systems. Serial identification (EEPROM) in accordance with the SFP MSA is available.
