End Lit PMMA Fiber Optic Harnesses

The only UK manufacturer of raw fiber for fiber optic 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 offically authorised 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.

Fiber Specifications

Core material Polymethyl Methacrylate
Cladding material Fluorinated Polymer
Refractive index 1.49
Numerical aperture 0.5
Refractive index profile Step index
Operation temperature range -55°C to +70°C (-67°F to +158°F) in low humidity; <60°C (140°F) at 95% RH (attenuation change is within 10% after 1000 hours except for that due to absorbed water).
Please note that fiber can become brittle at lower temperatures.
Sheathing specifications Outer sheathing material TP519 is a thermoplastic low-smoke halogen-free flame retardant compound with low toxic fume emission.
TP519 toxicity index (NES713) 1.3
TP519 halogen acid gas evolution (BS EN 50267-2-1) <0.5%
TP519 smoke emission 3m cube test (BS 7622) Pass
