Wavelength of a 25km optical module
This module is designed for single mode optical fiber and operates at a data rate of 100Gbps at the nominal DWDM wavelength from 1528. The Brocade® 32G extended long wavelength (ELWL) SFP+, part of the Brocade family of optical transceivers, is optimized for Brocade 32G director and. The common 100G optical standards, such as 100G SR4, 100G LR4, 100G CWDM4, 100G PSM4, and 100G ER4 optical modules, utilize four 25G optical channels for either parallel transmission or WDM transmission. Short-distance transmission usually refers to distances below 2km, medium distances range from 10-20km, and distances greater than or equal to 30km are considered long-distance.
