The SFP optical fiber module product is a relatively late optical module, but it is also the most widely used optical module product at present. The size of the SFP optical fiber module is at least half that of the GBIC optical module, and more than double the number of ports can be configured on the same panel. Since the SFP module is basically the same as the GBIC in function, it is also called miniaturized GBIC (Mini-GBIC) by some switch manufacturers.
As a company dealing with China qsfp transceiver, we remind you that SFP fiber modules are sold on the market in a variety of transmitter and receiver types, allowing users to choose the appropriate optical module for each link to achieve on available fiber types (such as: multi-mode fiber or single-mode fiber) light transmission.
SFP fiber module 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 module 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.
SFP optical fiber modules are expected to operate at data transfer rates of 5 gigabits per second (5Gbps) or higher. SFP optical fiber modules can be easily interchanged. Therefore, compared with traditional soldering modules, SFP optical fiber modules 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 module can provide great cost savings, whether for maintenance or upgrades. The Huawei SFP compatibility matrix provides a comprehensive list of supported SFP modules, enabling users to select compatible modules for their networking needs. The sfp+ transceiver module is also important.
There are multi-mode fiber SFP fiber modules and single-mode fiber SFP fiber modules on the market, allowing users to choose the appropriate optical module for each link to achieve optical transmission on the available fiber types. In addition, there are electrical port SFP optical fiber modules, which allow host devices designed for fiber optic communication to communicate over unshielded twisted pair network cables. The new SFP optical fiber module 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 modules, such as: optical output power, optical input power, temperature, laser bias current, and optical module supply voltage.
