The QSFP+ and QSFP28 series of modules include distances from 100m to 80km in CDWM/LAN-WDM and 850nm wavelengths.
QSFP modules converts input channels of 25G/10G electrical data into 4 separate optical signals and multiplexes them into a single channel for 100G/40G transmission. Reversely, on the receiver side the modules demux the channels signals.
