In today’s networking climate, there exist many users in multiple locations that need to be connected via fiber optic cable to achieve secure communication across vast distances. In most times, the physical space that they occupy is quite small, hence, compact devices are needed. Due to this specific requirement, there has been an increase in demand for SFP modules in recent years. What is an SFP module and what are the advantages of installing these modules in fiber optic networking switches?
Small Form Factor Pluggable (SFP) is basically a fiber optic module that fits into an SFP socket or port on an Ethernet switch or media converter. It facilitates seamless conversion of Ethernet signals into optical signals to transfer and receive data.
SFPs are mainly classified based on their speed capabilities. Some of the types are 100Base, 1000Base Gigabit, and 10Gig (SFP+). For most Fiber SFP modules , the transmission speed is 1 Gigabit, but the newer versions such as SFP+ have a higher speed of transmission, from 10 to 25 Gigabit.Commercially speaking, there are certain abbreviations on the modules, such as SX, LX, ZX, EX, and so on. SX indicates multimode short-wavelength of 850nm, while the others indicate single mode wavelengths of varying capacities.
Also known as mini Gigabit interface converter (GBIC), they are used in network interface cards (NICs), Ethernet switches, firewalls, and so on to act as an interface between a network device or a devices motherboard and the networking cable. With an SFP module, you can configure several ports on the same panel. Most companies use switches with at least two or more SFP ports making them a part of the network topology such as ring, star, bus, and so on.
Here are some factors you need to consider when choosing an SFP module:
