Can optical modules only transmit over 10 kilometers
Single-mode optical modules are used for long-range transmission, typically 10 km, 40 km, and 80 km. At a wavelength of 850nm, a 100M optical module can transmit up to 2km, a 1G can transmit up to 550m, a 10G can transmit up to 300m, a 40G can transmit up to 400m, and 100G and 400G can transmit up to 100m. 1310nm: The attenuation of optical fiber at 1310nm is approximately 0. Unlike general optical modules with two ports (Tx and Rx), BiDi optical modules have only one optical port and use wavelength division multiplexing (WDM) technology to transmit and receive optical. There are three wavelength windows for 10G optical module communication applications, namely the 850nm window, 1310nm window, and 1550nm window. In practical single-mode. 10GBASE-LR is a 10-gigabit Ethernet optical standard that operates at 1310 nm over single-mode fiber (SMF), supporting link distances of up to 10 km. It is typically implemented using SFP+ transceivers and defined under IEEE 802. 1310 nm (with MMF): 1310 nm (commonly with SMF): 1550 nm (with SMF): According to ITU-T.
