Universal Connector Fixtures
KrellTech’s unique Universal Workholder supports all UPC connectors, ferrules, and Mil-spec termini in a single polishing jig. Components supported include SC, FC, ST, LC, MU, E2000, SMA 905, SMA906, M29504, LuxCis, ARINC 801, ELIO, MC5, RSC and many others.
High Capacity UPC Connector Workholders
Maximize production through-put with KrellTech's HiCap Workholders. Up to 28 UPC connectors can be quickly loaded and processed at a rate of 6 connector per second. An integrated pressure control mechanism guarantees positive contact across all connector endfaces.
Multi-Fiber Connector Fixtures
These fixtures are designed to meet the stringent endface geometries such as flatness and fiber protrusion required for multi-fiber ferrules. Connectors supported include MT, MTP, MTO, MTx and MT-RJ. Both UPC and angled fixture are available. Fixtures also available to support MMC connectors with TMT ferrules. All fixtures feature fast and positive "tool-less" ferrule loading. Simply (1) retract the clamp, (2) insert ferrule and (3) lock the clamp. Like all Krell workholders these fixtures feature independent suspension for equalized pressure distribution and optical aligned ferrule holders for superior endface geometry control.
Plastic Optical Fiber Workholder
Plastic optical fiber (POF) workkholders can polish over 500 fibers in less than 5 minutes. Adaptable bushing design can accommodate a large variety of fiber diameters. This fixture also features Krell's patented independent suspension design for superior pressure control.
Industry Standard and Custom Polishing Fixtures
Workholders are available for all industry standard optical connectors. These include SC, FC, ST, LC and many others. Both UPC and APC endface geometries are supported. Adapters can also be used for bare fiber polishing in these fixtures. KrellTech’s engineering team develops customized polishing equipment for all applications and optical requirements. We have designed fixtures for products ranging from cannula and illumination bundles, to waveguides and fiber arrays. When requesting a quotation please provide detailed application specifications and attach all relevant drawings and information.

Precision Rubber Pads, Glass Disks & Wear Liners
KrellTech offers precision-engineered rubber polishing pads, glass polishing disks, and wear liners designed for maintaining connector endface geometries, including apex offset, radius of curvature, and fiber protrusion/undercut. Our Telcordia-compliant rubber pads come in multiple durometers (hardness levels) to achieve the ideal finish for fiber optic connectors.
For flat surface processing, we provide glass disks, ideal for bare fibers, SMA connectors, and MT-style multifiber connectors.
Wear liners ensure smooth, controlled polishing across all KrellTech polishers, eliminating the need for messy lubricants. They are easily replaceable for both the base polisher and platen contact surfaces, improving system longevity and consistency.
Available Polishing Pads & Glass Disks
Our polishing pads and disks are available in 2”, 4”, and 5” diameters, with multiple durometer options:
🔹 40D Orange Pad – Flexible for controlled geometry adjustments
🔹 70D Purple Pad – Medium-hard for precision polishing
🔹 90D Black Pad – Firm support for maintaining surface integrity
🔹 Glass Disk – Ideal for flat surface processing
🔹 Hybrid Pads (Glass/Rubber) – Available in Black (60D) and Orange (70D)
🔹 Custom Requests – Enter specifications in the Custom Application Notes field
Wear Liners for KrellTech Polishers
Wear liners extend the life of KrellTech polishers and improve polishing consistency.

CleanTouch™
CleanTouch™ is an economic and ergonomic device for cleaning optical connectors and bare fibers. By merely touching a connector ferrule against the CleanTouch substrate, all contaminants are removed. Delicate bare fibers are easily cleaned without the possibility of breakage or damage to the endface surface.
SpecVision™ Video Inspection Scope
SpecVision™ is a video probe and fiberscope that engages directly with Krell polishing machines. This permits the viewing of polished optical surfaces while connectors or bare fibers are still loaded in the polisher. This in-line video inspection technique minimizes material handling and potential damage/contamination that may occur when transferring components from the polisher to a traditional microscope. SpecVision™ can interface with Scepter™, NOVA™, SpecPro™ and Rev™ Polishers.
NOVA™ Profile Inspection Module
NOVA™'s Profile Videoscope allows the real-time monitoring of component polishing. This videoscope aids with bare fiber/component positioning and confirms process completion. Teamed with measurement software, this system verifies the endface geometry of fibers, waveguides and arrays.
