100G Transceivers

100G QSFP28 and SFP56 transceivers are the workhorse of modern data center leaf-spine architectures, service provider aggregation layers, and 100G Ethernet/OTU4 backbones. QSFP28 covers the standard four-lane deployments, while single-lane SFP56 fits higher-density, lower-power server and switch ports. They support reaches from under 100 meters to 80 kilometers depending on variant, over both multi-mode and single-mode fiber. IT teams standardize on 100G for server-to-spine and inter-switch links where 400G density isn't yet needed but 40G no longer has enough headroom.
