Twentsche (Nanjing) Fibre Optics Ltd has two types of high-performance optical fibre in its product portfolio: single mode fibre for long-distance transmission and multimode fibres for use in local area networks.

TFO utilises the best processes available to produce the different fibre types. A preform made in the VAD process (Vapour Axial Deposition) guarantees a single mode fibre with excellent optical and geometrical properties, an appropriate telecommunication medium for the coming decades, suitable for use in all existing cable concepts.

Multimode fibres are made with the versatile MCVD process (Modified Chemical Vapour Deposition) enabling low loss and high bandwidth to serve in the most advanced data communication systems.

TFO's multimode fibres are protected with a dual layer coating of UV curable acrylate, especially designed to provide a low level of sensitivity to microbending.

An extensive quality inspection programme performed both during as well as after the production process guarantees the high quality of TFO optical fibres. The production process is governed by a certified quality management system conforming to ISO 9001.

A logistical system coupled to the quality inspection database ensures each fibre is matched to specific customer requirements.

TFO gives full technical support to help successful processing and application of its fibres.
