TECS Hard-Clad Fiber
FT-200-DMT
Advantages
• Hard cladding increases fiber strength and reduces static fatigue in humid
environments. It also protects the fiber during buffer stripping to prevent fiber
breakage.
• Provides efficient light coupling and superior transmission in tight bends due to
high numerical aperture.
• High core-to-clad bonding prevents pistoning and provides more stable crimp-
and-cleave or epoxy terminations.
• Small overall fiber size for small size constraints.
• High concentricity and core-to-clad ratio for excellent connection alignment,
fiber core positioning and high transmission bundles.
• TECS cladding is removable with acetone, enabling low-cost, highly reliable,
custom end designs.
• Custom fiber sizes and coatings are available for specific applications.
• Low-OH¯ fibers for visible to near-IR transmission
