2×2 Double-Clad Fiber Couplers

SKU: DCFC

Agiltron’ s double-clad 2×2 fiber coupler is made by fusing a large core fiber (200 µm) to the outer cladding layer of a double-clad fiber (single mode core surrounded by an inner cladding and an outer thick cladding). Light in the double-clad fiber’s (DCF) single-mode core propagates through the coupler with little loss. While the reflected lights are collected mainly by the thick outer cladding of the DCF and transferred to the 200 µm large core output fiber with ≥60% coupling efficiency. It forms a miniature fiber optical sensor head for various applications.

We offer one of the industry’s most comprehensive selections of fused fiber couplers and splitters, designed for a wide range of application scenarios. Backed by over 25 years of production and engineering expertise, our products deliver industry-leading performance, reliability, and cost-effectiveness.
