401/402 Fibre Optic Swivel

Medium voltage electrical swivel

The Model 401 Fiber Optic Swivel allows continuous rotation of an optical fiber system. The optical design is completely passive, so the FORJ can accommodate any data format at any of the standard transmission wavelengths.

It is configurable with a combination of multimode or singlemode channels up to a total of 31 passes. Up to 52 passes are available in singlemode only. Integral junction boxes are fitted with patch panels for easy connection of incoming cables. Any standard fiber connector type can be accommodated.

The Model 402 adds the option of up to 48 low power signals, Ethernet, or similar (50 V / 3 A). Both models can be fitted with either an incremental or absolute encoder.

The fiber optic swivel is certified as a flameproof (Ex d) enclosure. Ingress protection is IP66 / IP68-20 m.

All products can be modified to meet specific requirements. Installation, commissioning and service is available
