With network hardware and data center equipment, size or cost does not correlate to what’s the most important or critical in your network. The largest server or the priciest router may not be the most critical to keeping your operation working properly. Many pieces of network hardware can be smaller than your watch, and will still determine the success or failure of a network. One particular product line that can act this way are Cisco SFP’s. There are many different models of  SFP‘s from Cisco that will meet your requirements- This blog will help to explain their functions and capabilities.

Base-T SFP for Copper Networks operates on a standard Cat-5 cabling of link lengths up to 100 meters. It supports 10/100/1000 auto negotiation and auto MDI/MDIX. Compatibility for Base-T SFP‘s include Catalyst 2960 series switch, Catalyst 3560 series switch, 3750 series switch, and 3850 series switch. For routers, Base-T is compatible with the 2900 series routers.

The Base-SX SFP for Multimode Fiber  operates on legacy 50 micrometer multimode fiber. It supports up to 1 Km distance. Compatibility for Base-SX SFP’s include Catalyst 2960 series switch, Catalyst 3560 series switch, 3750 series switch, 3850 series switch, and the 4500 series switches. For routers, Base-SX is compatible with the 2900 and 3900 series routers.

Base-LX/LH SFP for both Multimode and Single-Mode fiber, while operating on a standard single-mode fiber-optic link spans up to 10Km in distance and up to 550 meters on any multimode fibers.  Compatibility for Base-LX/LH SFP’s include:

Catalyst 2960 series switch
Catalyst 3560 series switch
3750 series switch, 3850 series switch
4500 series switches.
For routers, Base-LX/LH is compatible with the 2900 and 3900 series routers

Base-ZX SFP operates on a standard single-mode fiber-optic link spans of up to 70km in length. While the SFP provides an optical link budget of 21 dB, the precise link span length depends on multiple factors which include fiber quality, number of splices and connectors. Compatibility for Base-ZX SFP‘s include the following:

Catalyst 2960 series switch
Catalyst 3560 series switch
3750 series switch
3850 series switch
4500 series switches.
For routers, Base-ZX is compatible with the 2900 and 3900 series routers
