SFP optical modules are modules used to connect the module's circuitry with optical or copper networks and are widely used in telecommunication and data communication applications. Optical modules are not standardized by any official standards body, but rather are specified by a Multi-Source Agreement (MSA) between competing manufacturers.
SFP optical modules are designed after the GBIC interface, which allows greater port density (number of transceivers per cm along the edge of the motherboard) compared to GBIC, which is why SFP is also called mini-GBIC. SFP optical modules are expected to operate at data speeds of up to 5 gigabits per second (5G bps), and possibly even higher. Since the optical module SFP can be easily interchanged, it is more convenient to upgrade and maintain the electro-optical or fiber optic network compared to the traditional welded module. Instead of replacing the entire board containing multiple soldered modules, individual modules can be removed and replaced for repairs or upgrades. This can save a lot of money in maintenance and upgrade work. 100g optical modules are popular in this field.
As a professional and reliable optical module supplier, we remind you that SFP optical modules have a wide range of multi-mode/single-mode fiber detachable interfaces, allowing users to select the appropriate transceiver based on the optical range required by the network. SFP optical modules are of different types, operate at different wavelengths and are suitable for various distances. The signal transmission rate of these modules ranges from 100Mbps to 4Gbps or higher. The working distance of these SFP transceiver modules can be from 500 meters to 100 kilometers. The working wavelengths of different SFP modules are usually 850nm, 1310nm and 1550nm. There are also CWDM type SFP transceivers available. For example, SXSFP uses 850nm up to 550 meters, LX SFP uses 1310nm up to 10km, and ZX SFP can reach 80km. And if you are interested in sfp+ transceiver module, you can contact us.
There are also copper SFP optical modules with copper interfaces, which allow host devices primarily used for fiber-optic communications to also communicate over unshielded twisted-pair network cables. Modern optical SFP optical modules support Digital Diagnostic Monitoring (DDM) functionality, also known as Digital Optical Monitoring (DOM). This feature enables users to monitor real-time parameters of fiber SFPs such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage. The DOM function of SFP is optional, it helps users to detect the working status of SFP in real time.
SFP optical modules connect network device motherboards (for switches, routers, media converters or similar devices) to fiber optic or copper network cables. SFP optical modules support communication standards, including SONET, Gigabit Ethernet, Fibre Channel and other communication standards. They also allow the transmission of Fast Ethernet and Gigabit Ethernet LAN packets over time-division multiplex-based WANs, as well as the transmission of E1/T1 streams over packet-switched networks.
