| Core material | Polymethyl Methacrylate |
| Cladding material | Fluorinated Polymer |
| Sheathing Material | 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. |
| Core Refractive index | 1.49 |
| Refractive index profile | Step index |
| Numerical aperture | 0.5 |
| 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. |
| 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 |
