Sheathed PMMA Fiber
Universal Fiber Optic Lighting manufactures high quality multi-stranded sheathed fiber on reels. These typically consist of 0.75mmm (0.03") PMMA fibers in multiples to create a fiber of larger active diameter.
These can be used for many lighting applications and we supply many manufacturers of fiber optic lighting with standard and custom fiber configurations.
Pricing is dependant on shipping quantity - please contact us for details. Minimum order quantity for this product is one reel.

Other Information
Stranded fiber cables using 1mm (0.04") and 1.5mm (0.06") fiber can be made to order as can mixed diameter bundles.
We can supply blank common ends and sized ferrules for installers to cut and fit the fiber on site.
Though making harnesses on site does not produce as good or even light output as properly factory terminated harnesses, sometimes it can be necessary to terminate the fiber on site and Universal Fiber Optic Lighting can supply suitably experienced fitters with the raw materials to do this.
These fibers can also be stripped back at one end to make starry effects through ceilings.
