10G-SR は OM3 で 300m <ref>[https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/datasheet-c78-736282.html#FeaturesandbenefitsofCiscoQSFPmodules Cisco SFP-10G-SR-S module (S-Class)]
The Cisco 10GBASE-SR module supports a link length of 26 meters on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). Using 2000 MHz<sup>*</sup>km MMF (OM3), up to 300-meter link lengths are possible</ref> だが、100G-SR は OM3 で 70m <ref>[[Cisco QSFP-100G-SR4-S]]
The Cisco 100GBASE-SR4-S QSFP Module supports link lengths of up to 70m over OM3 and 100m over OM4 Multimode Fiber with MPO connectors. It primarily enables high-bandwidth 100G optical links over 12-fiber parallel fiber terminated with MPO multifiber connectors. QSFP-100G-SR4-S supports 100GBase Ethernet rate.</ref> までとかなり短くなっているため、要注意。
