The MPO chassis a.k.a. MPO fiber patch panel is designed to support the high-density optical network. With its compact structure, more space-saving is enabled as it can be deployed in the same server cabinet as the other optical equipment. The MPO chassis can be mounted on a 19-inch network cabinet and is available in 1U or 2U types. The 1U MPO chassis can support up to 5 MPO cassettes (these are loaded with either SC or LC adapters and a fanout cable with an MPO connector and branch out into SC or LC connectors) while the 2U MPO chassis can support up to 14 units of cassettes.
