There are numerous different types of fiber optical transceivers available in telecommunication market that can be used for various applications. When you choose fiber optic transceivers for your fiber networks, do you know how they work? What are their specific applications? This article mainly contributes to answering those two questions.

Before we discuss the two important aspects, it’s necessary to know the structure of a fiber optical transceiver, so that a better understanding of its working principle can be obtained.

Just as its name show, a fiber optic transceiver contains a fiber optic transmitter and a fiber optic receiver in a single module. There are four types of source for the transmitter that can convert the electrical signals into optical signals.: LEDs(light emitting diode), fabry-perot (FP) lasers, distributed feedback (DFB) lasers and vertical cavity surface-emitting lasers (VCSELs). They are tiny semiconductor chips. In a fiber optic receiver, semiconductor detectors (photodiodes or photodetectors) are used to convert optical signals to electrical signals.

A fiber-optic transceiver is known for receiving information from one end of the optical fiber and sending it through another fiber. The transmitter and the receiver are arranged in parallel in a fiber optic transceiver, so they can operate independently. And both the receiver and the transmitter have their own circuitry and can handle transmissions in both directions. In the fiber optics, information is sent in the form of pulses of the light. The light pulses have to be converted into electrical ones in order to be utilized by an electronic device. This process is done by the fiber optic receiver. In its fiber optic data links, the transmitter converts an electrical signal into an optical signal, which is coupled with a connector and transmitted through a fiber optic cable. The light from the end of the cable is coupled to a receiver, where a detector converts the light back into an electrical signal.

Fiber optic transceivers are utilized in various applications. Networking applications and radio applications are the most common places that they are deployed. Other target applications include FTTH (fiber to the home), Base Station (3G SFP CPRI/ 6G SFP+ CPRI), Fibre Channel (4G SFP/ 8G SFP+) and Ethernet systems (from 100Mbps to 10Gbps with different form factor / SFF, SFP, XFP and SFP+).
