Items like Cisco SFP 1.25G Transceiver Module

C-Light transceivers family includes Cisco SFP 1.25G All products are compatible with MSA. They are suitable for Fast Ethernet, Gigabit Ethernet, SDH/STM and Fiber Channel network system. Data rate ranges from 155M to 10GB. Distance reach from 80m to 80km in MMF and SMF. These products can be compatibly used in brands devices of 3COM, Alcatel, Cisco, Extreme, Foundry, HP and Juniper. And the SFP module are from 1000Base to 4Gbase. The  are 2.5G.Price is different according the size of capacity. Cisco SFP Transceiver Module Cisco SFP 1.25G  GLC-LH-SM hot-pluggable module, the greatest rate up to 10G, multi-use LC interfaces. SFP(small form pluggable) can be understood since the upgrade version of GBIC. SFP module volume ratio reduced by half than GBIC module, the identical panel could be configured in additional than double of ports. Other functions of Cisco SFP 1.25G are do i think the GBIC basicly .

Ingellen's Cisco SFP 1.25G optical module is Small Form Factor Pluggable (SFP) optical transceiver which are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). 1.25G SFP module is a compact optical transceiver and all equipped with the industry standard LC optical connector.  Our Cisco SFP 1.25G module interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. The capacity data rate of SFP module is 1.25 GigaBit.  Ingellen manufactures Multi-Rate 100Mb/1.25G for up to 200km distances.GLC-SX-MM Custom service for Cisco compatible 1.25G SFP like GLC-SX-MM, GLC-LH-SM, GLC-EX-SM are also avalible at Ingellen.com.Items like Cisco SFP Modules(cisco mini gbic) tend to be smaller and so are just about half the dimensions of GBIC optics. These modules send speeds that range between 100Mbps to about 4+Gbps. Their transmission length begins at pproximately 500 meters and goes up to 120+ kilometers.
