FIBER OPTIC ENCAPSULATION

Fiber in metal tube (FIMT)

Cables

Over 80.000 possible configurations, each suitable for multiple applications.

Cable layers

Stainless Steel Tubes can be combined with additional layers, which do not necessarily need to be a metal tube too.

Layer options

All our FIMT products are delivered with a test report

The reports are in accordance to EN 10204 /2.2 and include the following tests:

Actual tube length measurement
Actual tube diameter measurement
Welding depth measurement
Accurate EFL measurement
Optical Fiber attenuation measurement
Water penetration test, if applicable
