Cleaved-MPO Connector

The conventional APC MPO/MT connector relies on a polished end face so that 12 or more fibers in the connector are polished to an optical finish. 2 such connectors are pushed together so that each of the 12 polished fibers in the ribbon makes physical contact with fibers in the other connector.

In practice, these connectors must be cleaned and used with extreme care.  Any dust or contamination on the end of the connector will prevent physical contact between one or more of the fiber pairs, seriously degrading the optical performance of the connector.

Oxford Fiber has developed a Cleaved-MPO connector. A ribbon of 12 optical fibers are angle cleaved at 8 degrees from perpendicular. They are inserted into a pre-angled ferrule and accurately glued into position so that the fibers are recessed from the end of the ferrule. They are then anti-reflection coated. When MPO connectors are connected together, there is therefore an air-gap between the end of the mating fibers. The optical loss is acceptably small with little back-reflection due to the anti-reflection coating.

The Cleaved-MPO connection is designed to have a gap between mating fibers and so the presence of dust or contamination does not have a significant effect. Therefore the connection is dust-insensitive and the connector ends can be simply cleaned. Consequently, the Cleaved-MPO connector massively increases the reliability of the optical network.

These connectors are used in:

  • Networks requiring reliable connections
  • Outside plant
  • MDU-FTTP cabling
  • Radio Access Networks
  • Cable TV
  • Optical backplane interconnects

The connectors are fusion-spliced onto field fibers to allow the installers to configure the optical network with a connector with performance equivalent to a factory-pre-polished jumper lead. The connector is packaged in a bubble pack and can be spliced with a range of industry-standard ribbon fusion splicers. The connector can be attached to a variety of different cable types.

Angle Cleaving

Telecommunications uses light travelling in an optical fiber and fundamental to this technology is the ability to produce a cleaved end face so that the light can get in and out of the optical fiber. Oxford produces angled cleaved ends so that the back-reflection from the cleaved end face is removed, avoiding optical noise in the telecoms system.

The Ox-SAC-08 angle cleaves a single optical fiber. Typically it is used in the field for installation of pre-terminated optical connectors. The angled end ensures that the FAST connectors work across the full operating temperature range.   Alternatively, the Ox-SAC-08 is used to eliminate reflections in fiber sensor arrays such fiber Bragg gratings used in monitoring wind turbine blades. These cleavers are protected by European and US patents.

The Ox-RAC-08 angle cleaves multiple optical fibers in a ribbon. This ability is truly unique and of great use to customers who want to connect optical fibers to planar optical waveguides such as laser, detectors and splitters.
