Product Details
1.25G MM 850nm SFP Fiber Module With Duplex LC Connector
Product Characteristic:
1. Small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver.
2. The form factor and electrical interface are specified by a multi-source agreement (MSA).
3. It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable.
4. It is a popular industry format jointly developed and supported by many network component vendors.
5. SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards.
6. Simultaneously comply with 1.25Gb/s 1000Base-SX Ethernet and1.063Gb/s Fiber Channel.
