End Lit PMMA Fibre Optic Harnesses

The only UK manufacturer of raw fibre for fibre 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 fibre if required.

Our PMMA fibre products are manufactured from Mitsubishi / ESKA raw fibre. We are an offically authorised supplier of Mitsubishi fibre products.

End lit PMMA fibre comes in two configurations - single sheathed or unsheathed strands of 0.25mm, 0.50mm, 0.75mm, 1mm, 1.5mm or 2mm diameter fibre, or as multiple sheathed strands of 0.75mm fibre.

Single strands of fibre 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 fibre bend radius.

Fibre 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 in low humidity; <60°C at 95% RH (attenuation change is within 10% after 1000 hours except for that due to absorbed water). Please note that fibre can become brittle at lower temperatures.
Sheathing specifications Megolon S540 is a thermoplastic, halogen free cable sheathing compound which exhibits an excellent level of fire retardancy. This product is specifically aimed at designs of cables requiring a good degree of flexibility and the ability to meet the more stringent fire test specifications.
S540 Toxicity Index (DEF STAN 02-713) 0.4
S540 Halogen Acid Gas Evolution (IEC 60754-1) Zero
S540 Flammability Temperature Index (ISO 4589-3) 330°C
