The QSFP-100G-B20U4-I and QSFP-100G-B20D4-I operate in pairs, with one required at each end of the optical fiber. In the vast ecosystem of network infrastructure, the humble 100M optical transceiver (or 100M SFP module) remains a critical workhorse for enterprise access layers, industrial networks, and legacy system upgrades. Choosing the right one, however, can be a complex puzzle of compatibility, fiber. The Cisco 100GBASE Quad Small Form-Factor Pluggable (QSFP) portfolio offers customers a wide variety of high-density and low-power 100 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider. This may immediately raise concerns about the need to install extra fiber cables, as the IEEE Std 802. Unlike traditional transceivers, which require two fibers, BIDI SFPs use Wavelength Division. 3bm 100GBASE-SR4 Ethernet transport protocol, with optional multi-rate versions compatible with 100G Ethernet, OTN OTU4 and 128GFC.
