FiberFin

What FiberFin does

FiberFin, Inc. is a privately held distributor and custom assembly manufacturer of polymer optical fiber (POF) products, headquartered in Yorkville, Illinois. Founded around 2002 and led by founder/CEO Paul Mulligan, the company operates as a one-stop shop for POF, carrying over 1,500 stock-keeping units spanning bare fiber, jacketed cables, connectors, active components, cable assemblies, termination tools, and specialty medical-grade fiber. Its technology stack centers on plastic optical fiber—a short-distance, EMI-immune, cost-effective alternative to glass fiber used in industrial control links, automotive networks, medical illumination, sensing, and decorative lighting. Proprietary capabilities include POF termination automation, custom cable and splitter assembly manufacturing, and online Custom Cable Builder and Splitter Builder configurators with real-time pricing, supported by an advanced fiber search tool and hourly-updated inventory feeds.

The company's business model is primarily transactional product sales through its own e-commerce storefront (store.fiberfin.com), augmented by direct phone/email sales for larger and international orders, with bulk-tiered unit pricing (volume discounts of 1-75% across product lines), net-30 terms for domestic accounts ($100 minimum), and higher minimums ($500) for international orders. Revenue is split across POF product resale (one-time sale) and custom assembly manufacturing (cut-to-length, final-sale bespoke builds). It serves five primary verticals—medical (e.g., Ondine as a named 2020 Supplier-of-the-Year customer, CAT/MRI manufacturers, minimally invasive surgery), industrial manufacturing (factory automation, robotics, sensor links), automotive (infotainment/MOST bus), military/biometrics, and lighting. FiberFin is the exclusive U.S. distributor for Toray RAYTELA PQE medical fiber, the primary U.S. distributor for Mitsubishi's ESKA line (20+ year relationship), and the worldwide distributor for Optimedia's OM-Giga graded-index POF. Channel partners include Firecomms (transceivers) and Rennsteig (termination tools), with go-to-market supplemented by the FiberCast educational platform and a presence at industry tradeshows (OFC, ICPOF, SEMA, Electric & Hybrid Vehicle Technology Expo).

Scaling context: FiberFin operates with a small (1-10 employee) single-facility footprint, ships globally under U.S. export controls, holds no disclosed institutional funding, and reports no acquisition or restructuring activity; revenue is not publicly disclosed. Its competitive position rests on distribution scale (largest POF catalog globally per company claim), long-tenured OEM partnerships, and custom-assembly manufacturing capability rather than on software or AI platforms.
