Filling compound
In general, filling compounds for Fiber in Metal Tubes are used to protect the fibers from moisture and mechanical stress.
Optical fiber
Diameter, coating, bend resistance & coloring are all things that must be considered when choosing fiber a type.
We split fiber into two main categories:
Common Standard Fiber Types:
- G.652.D
- G.657.A1
- G.657.A2
- G.655
- etc.
Common Speciality Fiber Types:
- Copper Coated Fibers
- Aluminum Coated Fibers
- Gold Coated Fibers
- Buffered Fibers
- Polyimide Coated Fibers
- etc.
Single Layer Optical Core
Reinforced Optical Core
Special Sensing Core
Quality? We embody it.
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
How's FIMT made?
Peter Basic, our former head of R&D runs you through the FIMT production process.
Our latest FIMT insights
Why excess fiber length (EFL) matters?
For application, where a stainless-steel tube is needed to protect optical fibers against the surrounding influence, one abbreviation is catching one of the most important attention to consider. The so called “EFL”.
FIMT, FIST, SST? Deciphering the abbreviations.
When you work or deal with cables which contain optical fiber, you probably noticed designations like “FIMT”, “FIST”, “SST” or maybe other abbreviations which are related to a fiber optic cable. But what do those abbreviations stand for exactly and what is the meaning behind these terms?
