The SFP EX 1G transceiver
The 1000Base-EX SFP module is designed for data transmission using two single-mode (SM) fibers. It transmits data at speeds of up to 1.25 Gbps, over distances of up to 40 km. It operates at a TX wavelength of 1550 nm and has an LC/UPC duplex optical connector type. Compatible with the SFP MSA standard. Commonly known as miniGBIC.
Digital Diagnostic Monitoring (DDM) function enables real-time monitoring of optical parameters such as output power, input power, temperature and supply voltage to help manage and optimize network performance.
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.
