Giganet MTP/MPO 24 fiber ferrule cable assemblies are designed for cable infrastructures which are currently used for, or which are due to be upgraded to, parallel optics 40/100G protocols such as 100G BASE-SR10 or 40GBASE-SR4. The Assemblies are built using 24 fibre ferrule interface, MTP/MPO connectors, which can be used directly with CFP/CXP 100G transceivers or, when used together with transition modules/cables, can provide 40/100G parallel transceivers or legacy non-parallel optics 4/8/10/16G Ethernet/ fibre channel protocol networks.
