This MPO/MTP fiber optic cable houses 12 fibers and lets you interface between different networking devices of varying speeds. For example, you can set up a one-to-one connection between two 40Gbps switches or servers. Alternatively, you can connect a 40Gbps switch and break out the 40Gbps into six duplex 10Gbps LC connections on a patch panel or network cassette, which then fans out to individual 10Gbps devices. The MTP connector provides twelve times the density of an SC connector and saves circuit card and rack space. Plus, the push-and-pull tabs optimize accessibility by letting you install or remove the connectors with one hand without needing additional tools. The MTP to MTP cable is housed in a plenum-rated jacket and is ideal for installations where CMP fire rating is required. Each OM3 fiber cable has been individually tested for insertion loss and return loss. The full test report is included in each cable bag. The MPO12PL3M from StarTech.com is backed by a lifetime warranty.
