The optical fibre connects the light to the controller arm allowing the diver to remotely operate the lights when connected to a camera tray. You can control up to two lights simultaneously with one controller arm. For a longer cable length see the 2 meter option (2M Optical Fibre). The Optical Fibre cable can be used with the Remote Control units on the following lights:
