Ring of Fire: New Lensed Fiber Offering

July 31, 2025

Moog is now offering services to manufacture fiber optic cables with lenses formed at the end of the fiber cable. This technique optimizes the coupling efficiency by carefully managing the spot size and placement from an emitter or into a detector. This technology is fast becoming a requirement for the aerospace industry utilizing optical sensing at Ultraviolet, near infrared, or other application defined wavelengths. By integrating cutting-edge technology in our manufacturing processes, COTSWORKS offers very high-quality solutions tailored for harsh environments.

Current equipment utilizes the “Ring of Fire” which is fusion splicing technology developed by 3SAE Technologies. It is designed to perform high-quality splicing of specialty optical fibers including those with large cladding diameters or non-standard coatings which are challenging to process with standard fusion splicers. The “Ring of Fire” technology produces a ring-shaped plasma arc. This results in uniform heating around the fiber tip which minimizes loss and accommodates specialty fiber coatings. It also achieves a higher temperature than standard fusion splice equipment supporting the specialty fiber use and improved end face control.

Cables can be of bare, buffered, coated, jacketed types and made with multimode glass in multiple diameters. Endface images and IL and RL testing are available along with OTDR or OBR traces as well if required. Cables can be processed in or along with media processed within the FORCE clean room for applications ranging from imaging sensors, targeting spots, or space applications.
