The 1G SFP BX transceiver 20 km
The 1000Base-BX SFP optical module is designed for data transmission using a single single-mode (SMF) fiber. It transmits data at speeds of up to 1.25 Gbps, over distances of up to 20 km. It operates at TX 1310 nm/ RX 1550 nm wavelength and has LC/UPC simplex optical connector type. Compatible with SFP MSA standard.
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 TX transmitter on one side corresponds to the RX receiver of the module on the other side, analogous to the picture above. The transceiver matching LO-SF-1G-325-20L is: LO-SF-1G-5S3-20L.
