Model 401 / 402 Fiber Optic Swivel

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

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

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

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

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