The 1G SFP BX transceiver 20 km
The 1000Base-BX SFP optical module is designed for data transmission using a single single-mode (SM) fiber. It transmits data at speeds of up to 1.25 Gbps, over distances of up to 20 km. The transceivers operate using WDM (Bi-Di) technology to provide bidirectional transmission over a single single-mode fiber. The built-in DFP laser transmits data at the TX 1310 nm transmitter wavelength, while the PIN photodetector receives the RX 1490 nm wavelength. The transceiver has an LC/UPC duplex optical connector type. The modules are compatible with MSA's SFP standards and compatible with devices from various manufacturers, making them an ideal choice for stable and reliable network connections.
Before shipping, the modules are individually coded to ensure full compatibility. If you did not find the manufacturer's name in the list, please select the "Other" option at the end of the list.
Example application of SFP BiDi 1000BASE-BX
BiDi transceivers always work in a pair, where the wavelengths are matched crosswise so that the wavelength of the insert's TX transmitter on one side corresponds to the transceiver's RX receiver on the other side, analogous to the picture above. The matching transceiver for LO-SF-1G-3S4-20L is: LO-SF-1G-4S3-20L.
