Fibra Optica Multi Mode

TKF multimode fibres are produced with the MCVD process enabling low loss and high bandwidth to serve in most advanced data communication systems. The specially designed primary coating provides a low level of microbending sensitivity.

TKF multimode fibres comply with ISO 11801, IEC 60793 A1a and A1b standards and can be used in various applications like:

 • OM1 and OM2 grades of 50/125µm fibre and enhanced versions

 • GigaBand 150, GigaBand 300 (OM3) and GigaBand 500 fibre, laser optimised 50/125 µm types for 10 Gbit/s transmission at 850 nm over 150, 300 and 500 metres
 • OM1 and OM2 grades of 62.5/125 µm fibre and enhanced versions
 • GigaBand 300 and GigaBand 500 fibre, laser optimised 62.5/125 µm types for 1 Gbit/s transmission at 850 nm over 300 and 500 metres
