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 0.75mm, 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.
|Core material||Polymethyl Methacrylate|
|Cladding material||Fluorinated Polymer|
|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.
