1000BASE-EX SFP 1550nm 40km DOM Duplex LC/UPC SMF Optical Transceiver Module
$18The 1000BASE-EX SFP 1550nm 40km Optical Transceiver Module is specifically designed for long-distance Gigabit Ethernet communication, utilizing a 1550nm wavelength to achieve stable and high-performance data transmission over single-mode fiber (SMF). Compared to the 1310nm wavelength, the 1550nm wavelength offers lower fiber attenuation, making it more efficient for long-haul optical transmission over 40km or more. The 1550nm wavelength is…
