helping to make SDH SFP space-saving. Signal transmitting

SDH SFP is really a compact optical transceiver found in optical communications both for telecommunication and knowledge communications applications. Cisco Transceiver Modules support Ethernet, Sonet/SDH and Fibre Channel applications across all Cisco switching and routing platforms. Cisco pluggable transceivers give you a convenient and value effective solution for the adoption in data center, campus, metropolitan area access and ring networks, and utility area networks. Cisco portfolio of hot pluggable interfaces supplies a rich set of choices with regards to speeds, protocols, reaches and supported transmission media.

Cisco SFP can be regarded as the upgrade version gbic module, SFP is short for Small Form-factor Pluggables, unlike GBIC with SC fiber optic interfaces is by using LC interface and also the main body size of SFP is only about 50 % of GBIC, helping to make SDH SFP space-saving. Signal transmitting rate of such modules vary from as much as 4Gbps or maybe more, working distance of these SFP transceiver modules may be from 500 meters to 100 kilo meters, working wavelength of numerous SFP modules are usually 850nm, 1310nm and 1550nm, there’s also CWDM type SFP transceivers available.
