QSFP28 fiber transceivers are made to carry 100G Ethernet, EDR InfiniBand or Fibre Channel. Typical QSFP28 transceiver type is also used with direct-attach breakout cables to transfer one single 100GbE port to four independents 25 gigabit Ethernet ports (described as QSFP28-to-4x-SFP28).
QSFP28 transceivers are available in these types including 100G QSFP28 LR4 10km,100G QSFP28 LR Lite 4km,100G QSFP28 LR4 DML OTU4,100G QSFP28 SR4 OM4 100m,100G QSFP28 CWDM4 2KM,100G QSFP28 PSM4 2KM. 100GBASE-LR4 QSFP28 works on single mode, 100GBASE-SR4 QSFP28 works on multimode OM3/OM4/OM5,100GBASE-CWDM4 QSFP28 is for long distance transmission, 100GBASE-PSM4 QSFP28 is for high speed and low power consumption.
The 100G-QSFP28-SR4 is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP28 Transceiver for IEEE 802.3bm, 100GBASE SR4 Applications,or 40 Gigabit Ethernet and Infiniband FDR/EDR Applications.
The module converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission.
