Fiber optic transceivers, also called optical module, are composed of optoelectronic devices, functional circuits, and optical interfaces. It includes transmitting and receiving parts.
The function of the optical module is photoelectric conversion. The transmitting end converts the electrical signal into an optical signal. After being transmitted through the optical fiber, the receiving end converts the optical signal into an electrical signal
According to different module packing , can be divided into qsfp, qsfp28, CFP, cfp2, cfp4, CXP, SFP, CSFP, SFP +, GBIC, XFP, xenpak, X2, SFF and other types.
As a professional optical transceiver manufacturer, PHXFIBER provides different modes of optical transceiver wholesale, such as multimode fiber transceiver, and single-mode fiber transceiver. The optical transceiver price is reasonable and attractive. Optical transceiver types are various, and there's always one for you.
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.
