MPO is short for “Multi-fibre Push On”. MPO cables can only be manufactured in a factory and are not able to be assembled at site as some other connector types are.
The MPO connector uses tightly held tolerance stainless steel guide pin tips with an elliptical shape. The elliptical shaped guide pin tips improves guidance and reduces guide hole wear over time.
MTP/MPO connectorised ribbon fibre cable assemblies provide reliable high performance interconnects of up to 24 fibres in a small footprint. The MTP/MPO connectors utilize the precision moulded NTT compatible ferrule which connects four to 24 fibres using bare ribbon or ruggedized ribbon cable. Alignment between mating ferrules is accomplished using two precision guide pins that are pre-installed into the designated male connector.
MTP/MPO connectors are used with single-mode and multimode fibre-optic cables. The MTP/MPO is a connector manufactured specifically for a multifibre ribbon cable. The MTP/MPO single-mode connectors have an angled ferrule allowing for minimal back reflection, whereas the multimode connector ferrule is commonly flat. The ribbon cable is flat and appropriately named due to its flat ribbon-like structure, which houses fibres side by side in a jacket. The typical insertion loss for matched MTP/MPO connectors is 0.25 db. From a design perspective, it is recommended to use a loss margin of 0.5 dB or the vendor recommendation for MTP/MPO connectors.
