Proton™ Field And FTTX Polisher For Portable Fiber Optic Connector Polishing

Portable fiber optic connector polishing requires a system that can combine mobility, repeatability, and dependable endface quality in a compact format. KrellTech’s Proton™ Field and FTTX Polisher was developed for applications where technicians need the flexibility to polish connectors in the field, in tight workspaces, or in environments where larger benchtop systems are not practical.

Proton™ is a handheld, battery-operated fiber optic polisher designed to achieve Telcordia-compliant singlemode UPC and APC finishes. Its portability makes it especially useful for field service, repair, and installation work, while its polishing design helps maintain the process control needed for consistent results.

One of Proton™’s key advantages is its ability to polish in almost any orientation, including sideways. This makes it a strong fit for work in confined spaces such as telecom cabinets, wire closets, LAN cross-connects, CATV nodes, and other installations where access can be limited and maneuverability is important.

The system incorporates the same Independent Suspension and optically aligned workholder design found in KrellTech’s larger polishing platforms. Independent Suspension helps promote controlled polishing pressure at the connector, while optically aligned polishing helps support consistent endface geometry. Adjustable pressure gives operators added control during processing, and random orbital motion contributes to a uniform polishing action.

Proton™ also features interchangeable connector workholders, helping users adapt the system to a variety of connector styles and application requirements. In addition to industry standard connectors, Proton™ can support mil-spec components and termini including M29504, ARINC 801, ELIO LuxCis, and others. This flexibility makes it useful across a wide range of markets, from telecom and data centers to aerospace, defense, and R&D environments.

For organizations working in field deployment, maintenance, or repair, Proton™ offers a practical combination of portability and performance. Whether the job involves servicing installed networks, supporting ruggedized applications, or polishing connectors where space is limited, Proton™ provides a compact solution designed around real-world fiber optic polishing needs.

KrellTech also backs its equipment with technical support, application knowledge, and more than 30 years of experience manufacturing fiber optic polishing equipment. That combination of product capability and process expertise helps customers approach field polishing with greater confidence.
