New keyed SMA fibre optic system ensures consistent mated performance

OMC has launched a new, Keyed SMA (KSMA) connector and diode receptacle system for its wide range of fibre optic transmitters and receivers which offers the rotational consistency of a keyed connector alongside the security and reliability for which the SMA connector is renowned. The KSMA fibre optic connector system combines a new connector and diode housing design, which OMC describe as delivering the best of all worlds. Unlike the standard SMA connector, which can be inserted at any rotation about the ferrule axis, the company’s KSMA system incorporates a mechanical keyway mechanism, thus eliminating rotational variation when a cable is mated to the transmitter or receiver. The connector continues to feature the secure hexagonal lock-nut fixing of their standard SMA connector, ensuring maximum long-term integrity of the connection. OMC’s commercial director, William Heath explains: “Controlling rotational variation is important because if a cable is disconnected and then reconnected, traditional non-keyed SMA devices can rotate throughout the full 360 degrees, introducing the possibility of performance variations and limiting repeatability, which can be problematic in optically demanding applications. Our new KSMA connector system ensures that the link will always deliver consistent, repeatable performance.”
