Underwater slip rings (FORJ)

Posted on By lily.yu

Underwater Slip rings, also called "FORJ" (“Fiber Optic Rotary Joints”),rotary joint or rotary connector, applied for connection of optic, signals and electrical transmission. with good performance of low loss, non-electromagnetic leak, anti-magnetic, non-contact transmission, non-resistance.
Main properties:

* Reliable signal transmission without interference;
* Insensitive to electromagnetic interference;
* Totally harmless;
* No earthing or galvanic isolation necessary;
* Extremely reliable security against eavesdropping;
* Wide ranges without intermediate amplification;
* High rates of transmission;

Really suitable for underwater application including: Subsea inspection and exploration, ROV, Diving system, Marine engineerings.
