End Lit PMMA Harnesses

Our range of standard PMMA end lit harnesses are available in either single or multi-strand configurations. We can also make custom harnesses with larger diameter fiber if required.

Our PMMA fiber products are manufactured from Mitsubishi / ESKA raw fiber. We are an officially authorized supplier of Mitsubishi fiber products.

End lit PMMA fiber comes in two configurations – single sheathed or unsheathed strands of 0.75mm, 1mm, 1.5mm or 2mm diameter fiber, or as multiple sheathed strands of 0.75mm fiber.

Single strands of fiber give starry points of light and normally require no termination, whilst multi-stranded varieties are normally terminated with a ferrule to allow the attachment of an end fitting.

Larger diameters are available on request with soft silicone at the ends of the tails for use when articulated fittings are used in a tight space for the fiber bend radius.
