Bundle Options

Optional fiber: all TOP® fibers

Effective end-face geometries: round, semicircular, square, rectangular, linear, ring, segmented ring

Design: single-branch, dual-branch or multi-branch

Bundle type: bonded end or fused end

Fused end: the fusing process merges the fibers in the bundle, eliminating gaps to form a honeycomb structure. This structure reduces signal loss and improves uniformity within the bundle, significantly raising transmission efficiency.

TOP® Fiber Bundle End-face Processes

Bonding

Bonded bundles offer unrivalled flexibility and can be made in a wide range of diameters and geometries.

Sorting

Sorting the fibers distributes power evenly between bundle branches and improves measurement accuracy through spatial mapping of the fibers.

Fusing

In fused bundles, eliminating the gaps between fibers raises the fill factor and improves transmission by up to 20%.

Anti-reflective (AR) Coating

AR coatings effectively reduce back-reflection at fiber end faces, directly improving transmission by about 3.5% per end face.
