The KSMA fiber optic connector system combines a new connector and diode housing design, which OMC describes as delivering the best of all worlds. Unlike the standard SMA connector, which can be inserted at any rotation around the ferrule axis, OMC's KSMA system incorporates a mechanical mechanism, thus eliminating rotational variation when a cable is mated to the transmitter or receiver. The connector still features the secure hex nut locking mechanism of OMC's standard SMA connector, ensuring maximum long-term connection integrity. OMC's Commercial Director, William Heath, explains: "Controlling rotational variation is important because if a cable is disconnected and then reconnected, traditional keyless SMA devices can rotate a full 360 degrees, introducing the potential for 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, steady performance.".

The industrial sector generally considers SMA (H22) type devices useful because the connector's locking nut, once tightened, ensures the fiber is firmly secured in place; other types, such as suspended devices, can allow the fiber to retract and change the link attenuation if tension is applied to the cable. The new KSMA diode housing also retains another important benefit of OMC's traditional PCB-mount SMA (H22 style) housing: its robust, all-metal design.

The new KSMA connector system is well-suited to industrial applications, particularly where cables need to be disconnected and reconnected, or where performance criteria are critical. Installation of the KSMA connector is simple: OMC states that, using new high-precision CNC machining capabilities, its keyway mechanism is designed for seamless engagement. As with its standard SMA connector, a small hex key is used to gently tighten the lock nut after installation. In addition to securing the connection, this reduces the likelihood of accidental or unintentional tampering. OMC's full range of transmitting (Tx) and receiving (Rx) devices can be incorporated into the KSMA housings.
