1.25G SFP optical transceiver is a compact and small form-factor pluggable transceiver module for telecommunications and data communication applications. The SFP transceiver usually use to connects the network equipment motherboard (router, switch, media converter or similar device) to the optical fiber or copper cable network. UnitekFiber as a professional fiber transceiver manufacture, we provide a series of SFP transceiver modules with 10km, 20km to 120km distance of SFP transceivers.
SFP transceiver is a compact and small form-factor pluggable transceiver module for telecommunications and data communication applications. The SFP fiber transceiver can be regarded as an upgraded version of the GBIC module. Different from GBIC with SC optical fiber interface, SFP has LC interface, and the main body size of SFP is only half of GBIC, and SFP has a higher density of use. SFP optical transceiver connects the network equipment motherboard (router, switch, media converter or similar device) to the optical fiber or copper cable network. At the same time, SFP is an industry standard supported by major telecom equipment suppliers. The SFP optic transceiver is designed to support SONET (Synchronous Optical Network), Gigabit Ethernet, Fibre Channel and other communication standards.
The 1.25G SFP transceiver type can include various variations based on specific requirements and technologies. Here are some common types of 1.25G SFP fiber module:
BIDI: BIDI SFP optical transceivers use a single fiber strand for both transmitting and receiving data. They are available in different wavelengths, such as 1310nm/1490nm or 1310nm/1550nm, allowing bidirectional communication over a single fiber. BIDI fiber transceiver must be used in pairs.
Dual Fiber: Dual fiber SFP optical transceivers utilize separate fiber strands for transmitting and receiving data. They are commonly used in applications where dedicated fibers are available for both directions of communication.
CWDM: CWDM SFP optical transceivers support multiple wavelengths of light transmission, allowing for the simultaneous transfer of data over a single fiber. They typically operate within the CWDM wavelength range of 1270nm to 1610nm and offer cost-effective solutions for expanding network capacity.
DWDM: DWDM SFP optical transceivers also enable multiple wavelengths of light transmission, but with a higher density and narrower wavelength spacing compared to CWDM. DWDM technology allows for increased data capacity over long-distance fiber optic links by utilizing different wavelengths for different data channels.
