Innofiber

What Innofiber does

Innofiber is a U.S.-based OEM design and manufacturing partner specializing in custom fiber optic cables, sub-assemblies, and optic light guides for mission-critical applications. Founded in 1989 and headquartered in Sterling, Massachusetts, the company operates an 18,000 sq ft facility that includes in-house optical fiber draw towers, multi-axis CNC machining, and a certified 1,200 sq ft Class 7 Clean Room for sterile medical builds. Its technical scope spans borosilicate, fused silica, PMMA, and quartz fibers with sheathing options ranging from chemical-resistant jackets to stainless steel and exotic metals, supporting operating temperatures up to 900°F.

The company serves five vertical markets — medical devices (its primary segment), analytical instruments, industrial automation, aerospace & defense, and semiconductor capital equipment — by integrating fiber optic solutions into OEM end-products such as surgical illumination instruments, endoscopes, wafer-mapping tools, UAV/LIDAR systems, and spectroscopy instruments. Its commercial model is project-based custom manufacturing, executed through a five-stage integrated service platform covering Conceptualize, Design, Commercialize, Manufacture, and Fulfill, with documented outcomes including $350K in first-year savings for a global medical device OEM and 99.5%+ on-time delivery on a surgical illumination replacement cable program. Innofiber holds ISO 13485:2016, ISO 9001:2015, FDA facility registration, CE marking, and RoHS/REACH compliance, and serves as a sole-source supplier to several major OEMs.

In April 2025 Innofiber merged with Acrolite, and in December 2025 PAVE Technology Co. joined, forming Connexis Group Inc. — a three-location U.S. manufacturing platform combining fiber optics, micro optics, and hermetic sealing capabilities. Innofiber continues to operate under its established brand as a subsidiary of Connexis Group.
