The QSFP28-BIDI-100G transceiver has a duplex LC interface suitable for short distance wiring connections in data centers, with a maximum connection distance of up to 150m; The QSFP28-SR4-100G has an MTP interface suitable for short distance cabling connections in data centers, with a maximum connection distance of up to 100m.
If the network requirements are upgraded from the original 10G or 25G to 100G, because 10G or 25G network cabling is mainly based on LC duplex multimode fiber, if you use a conventional 100G QSFP28 SR4 optical module, you need to use MPO 8-core or 12-core multimode fiber. On the basis of the original wiring, major adjustments have been made, and the cost is extremely high. 100G BIDI can effectively save the cost of fiber optic infrastructure and is widely used in the field of data centers. 2023年4月24日にFS.comより発表された
