What Kind of Switches and Patch Cables Should I Choose for SFP Transceiver?

Gigabit Ethernet has supplanted Fast Ethernet in wired local networks and becomes ubiquitous throughout the world, serving as one of the most prevalent enterprise communication standard. The Gigabit Ethernet standard supports a maximum data rate of 1 gigabit per second (Gbps)(1000 Mbps), 10 times faster than Fast Ethernet, yet is compatible with existing Ethernet. To link your switches and routers to a Gigabit Ethernet network, you need a Gigabit Ethernet transceiver as a transmission medium. This article intends to introduce the most commonly used one—SFP transceivers.


What Is SFP Transceiver?

SFP, short for small form-factor pluggable is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. SFP transceiver can be regarded as the upgrade version of GBIC module. Unlike GBIC with SC fiber optic interface, SFP module is with LC interface and the main body size of SFP is only about half of GBIC so that it can save more space. SFP interfaces a network device mother board (for a router, switch, media converter or similar devices) to a fiber optic or copper networking cable. It is designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards.

Types & Applications of SFP transceivers

SFP transceivers are available with various transmitter and receiver types, which facilitates users to select the appropriate optical transceiver for different optical reach and optical fiber type (single-mode fiber or multimode fiber) required by different link. SFP transceiver modules can be divided into several different categories:

TypesTransmission MediumWavelengthDistance

1000BASE-BX10 SFPSingle mode fiber1480-1500 nm downstream, 1260-1,360 nm upstream10 km

SFP transceivers are found in Ethernet switches, routers, firewalls and network interface cards. Storage interface cards, also called HBAs or Fibre Channel storage switches, also make use of these modules. Because of their low cost, low profile, and ability to provide a connection to different types of optical fiber, SFP transceiver provides such equipment with enhanced flexibility.
