FIBER IN METAL TUBES
Thin Wall Alu Layered
- 0.25 mm up to 0.3 mm aluminum wall
- Unique manufacturing
- Moisture tested
ACT
Some applications, especially OPGW cables requires a thin covering sheath which is made from aluminum material. Such tube designs are used to Increase the short time temperature of an OGWG or to protect the FIMT cable near the sea. The aluminum covering around a FIMT is also used for OPGW cables without grease. NBG is the only FIMT manufacturer which is able to provide a thin wall aluminum layer in the well-tried laser welding method. The aluminum layer, as well as all other components included in this product are produced according to the highest quality standards in the industry. The metal tube itself and also the outer aluminum layer protects the integrated optical fibers against mechanical stress, hydrogen and other environmental influence in order to provide maximum optical lifetime for their application. All dimensions of the product can be adapted to meet the requirements and needs to offer great performances in the field.
