Fiber Optic Transceivers

There are types of fiber optic transceivers to choose from, and there are some specifications of fiber optic transceivers that can help us to select.

1.Fiber mode: according to diameters or characteristics of fiber optic,fiber mode can be categorized into single-mode fiber transceiver and multimode fiber transceiver. The multimode fiber transceivers are usually used to transmit optical signals over short distances because the inter-mode dispersion is greater even the core diameters are larger. On the contrary, a single-mode fiber transceiver can transmit optical signals over long distances due to its small dispersion, but it can only transmit light in one mode. 

2. Sensitivity: the power at which the receiver of an optical transceiver module can receive optical signals within a range of bit error rate (BER = 10-12), in dBm.

3. Central wavelength:  there are mainly three central wavelengths for optical transceiver modules: 850 nm, 1310 nm, and 1550 nm.
