?????????? ??? 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.
