Cisco SFP 1.25G without significant sensitivity

SFP Transceiver Modules - 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 SFP Module are do i think the GBIC basicly . 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 approximately 500 meters and goes up to 120+ kilometers.Divided by rate:155M/622M/1.25G/2.125G/4.25G/8G/10G,155M and Cisco SFP 1.25G market is used more, 10G technologies are maturing, demand is always to increase quickly.The Cisco SFP 1.25G optical module is Small Form Factor Pluggable (SFP) optical transceiver, used in optical communications for both telecommunication and data bidirectional communications applications. It interfaces a network device mother board (for a switch, router or similar device) to a fiber optic or unshielded twisted pair networking cable. They simultaneously comply with Gigabit Ethernet as specified in IEEE Std 802.31 and 1x and 2x Fiber Channel as defined in FC-PI 13.03. The SFP (Small Form Factor Pluggable ) transceivers is compliant with SFP MSA (Multi-Source Agreement ) and SFF-8472. All modules satisfy Class I Laser Safety requirements in accordance with the international IEC-825 standards.
