How much optical attenuation should a 10km optical module have

Home / How much optical attenuation should a 10km optical module have

The module with a transmission distance of 10km does not need to be attenuated, and there will be no receiving overload. 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. This document describes how to calculate the maximum attenuation for an optical fiber. Actual attenuation requirements will vary depending on the specific transmitter output power and receiver sensitivity of the optical modules in use. 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.

The relationship between wavelength and transmission

The commonly used wavelengths in optical fibers are 850nm, 1310nm, and 1550nm, which have longer waveforms and therefore have relatively less attenuation.
