Plastic Cladded

Optical Fiber Cladding Material: Plastic

We often combine Fiber in Metal Tube (FIMT) cables with additional plastic layers to solve particular challenges. The plastic optical fiber cladding material options fall into two main categories: standard polymers and high-performance polymers.

The plastic sheath gives the cable an increased resistance to impact and mechanical stress. In addition, it allows for greater elasticity and lower weight than extra metallic layers. The plastic also serves as an excellent rodent deterrent, making the custom fiber optic cables perfect for direct-buried applications.
