Mode Classification and Application of SFP Optical Fiber Transceiver

The SFP optical fiber transceiver product is a relatively late optical transceiver, but it is also the most widely used optical transceiver product at present. The size of the SFP optical fiber transceiver is at least half that of the GBIC optical transceiver, and more than double the number of ports can be configured on the same panel. Since the SFP transceiver is basically the same as the GBIC in function, it is also called miniaturized GBIC (Mini-GBIC) by some switch manufacturers.

1. Mode classification of SFP optical fiber transceiver

As a company dealing with China qsfp transceiver, we remind you that SFP fiber transceivers are sold on the market in a variety of transmitter and receiver types, allowing users to choose the appropriate optical transceiver for each link to achieve on available fiber types (such as: multi-mode fiber or single-mode fiber) light transmission.

SFP fiber transceiver multimode: Almost all multimode fibers are 50/125μm or 62.5/125μm in size, and the bandwidth (the information transmission amount of the fiber) is usually 200MHz to 2GHz. The multimode optical transceiver can transmit up to 5 kilometers through multimode optical fiber. Light-emitting diodes or lasers are used as light sources. The pull ring or outer body color is black.

SFP optical fiber transceiver single-mode: The size of single-mode fiber is 9-10/125μm, and it has unlimited bandwidth and lower loss than multimode fiber. The single-mode optical transceiver is mostly used for long-distance transmission, sometimes up to 150 to 200 kilometers. Use LD or LED with narrow spectral line as the light source.

2. Application of SFP optical fiber transceiver

SFP optical fiber transceivers are expected to operate at data transfer rates of 5 gigabits per second (5Gbps) or higher. SFP optical fiber transceivers can be easily interchanged. Therefore, compared with traditional soldering transceivers, SFP optical fiber transceivers can make the upgrade and maintenance of optoelectronic or fiber optic networks more convenient. Due to its low cost, small size and ability to connect to different fiber types, the SFP optical fiber transceiver can provide great cost savings, whether for maintenance or upgrades. The Huawei SFP compatibility matrix provides a comprehensive list of supported SFP transceivers, enabling users to select compatible transceivers for their networking needs. The sfp+ transceiver module is also important.

There are multi-mode fiber SFP fiber transceivers and single-mode fiber SFP fiber transceivers on the market, allowing users to choose the appropriate optical transceiver for each link to achieve optical transmission on the available fiber types. In addition, there are electrical port SFP optical fiber transceivers, which allow host devices designed for fiber optic communication to communicate over unshielded twisted pair network cables. The new SFP optical fiber transceiver supports DDM (Digital Diagnostic Monitoring) function, also known as DOM (Digital Optical Monitoring). This feature enables users to monitor real-time parameters of SFP optical fiber transceivers, such as: optical output power, optical input power, temperature, laser bias current, and optical transceiver supply voltage.
