The Cisco SFP (Little Kind-Issue Pluggable) Gigabit Interface Converter (Transceiver) could be the business normal option for Gigabit Ethernet purposes on Cisco switches, routers or modular blades with SFP slots. the SFP is often a sizzling swappable I/O gadget which inserts into a Gigabit Ethernet port or slot. The SFP gives an interface with hyperlinks the port with the community.
Cisco SFPs are flexible and interchangeable with numerous types of Cisco goods. They will also be Employed in mixed combinations together with 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis.
There are several different types of Cisco SFP relying upon your specific application.
1000BASE-T SFPs for Copper networks operate on garden wide range Category five mini engine unshielded twisted pair copper cabling. Cisco 1000BASE-T SFPs are able to nearly 100m (328 ft) connection lengths. Cisco 1000BASE-T SFP modules aid ten/100/a thousand autonegotiation and Automobile MDI/MDIX.
1000BASE-SX SFPs are meant for Multimode Fiber Utilized Only. The 1000BASE-SX SFP is entirely suitable While using the IEEE 802.3z 1000BASE-SX standard. 1000BASE-SX SFPs work on legacy fifty μm multimode fiber backlinks approximately 550 m and on sixty two.five μm Fiber Dispersed Information Interface (FDDI)-quality multimode fibers around 220 m.
1000BASE-LX/LH SFPs are meant for the two Multimode and Solitary Mode Fiber purposes. The 1000BASE-LX/LH SFP is suitable Together with the IEEE 802.3z 1000BASE-LX typical. These SFPs operate on standard one-method fiber-optic hyperlink spans of as much as ten km and up to 550 m on any multimode fibers. When made use of over legacy multimode fiber kind, the transmitter needs to be coupled through a manner conditioning patch cable.
1000BASE-EX SFPs are made for Extensive-Arrive at, Single-Manner Fiber applications of as much as 40 km in length. A 5-dB inline optical attenuator really should be inserted among the fiber-optic cable along with the getting port within the SFP at Just about every end with the backlink for back-to-back again connectivity.
1000BASE-ZX SFPs are supposed for Extended-Reach, Solitary Method Fiber programs as many as approximately 70 km in length. The SFP supplies an optical website link funds of 23 dB, but the precise backlink span size will depend on several variables for instance fiber good quality, quantity of splices, and connectors.
