3SAE Large Diameter Fiber Cleaver

LCC II-A (Liquid Clamp Cleaver II-Angled)

The 3SAE Liquid Clamp Cleaver II LDF, is the most advanced large diameter angled fiber cleaver for circular and shaped optical fibers from 125 μm to 1000 μm. Liquid Clamp Cleaver II-A (LCC II-A) features angle cleaving with rotation up to 30°.


The primary cause of bad cleave angles is torsional strain in the fiber, induced by torque from conventional clamps. This patented process features a completely torque-free clamping system, which uses a proprietary metal alloy ingot that melts at less than the boiling point of water. This is a lead-free, cadmium-free alloy ingot specially formulated to solidify tightly around the optical fiber when cooled, providing torque-free clamping, even on non-round fibers such as Octagonal shape. A solid-state temperature control system rapidly liquefies and solidifies the alloy as needed. When the alloy ingot is depleted by use, it can be easily replaced. These unique alloy ingots are available exclusively from 3SAE Technologies.


The LCC II-A optionally leverages an integrated manual backstop within the cleaver housing that provides enhanced cleave performance for structured fibers. Alignment of the blade, backstop, and fiber is achieved via the integrated side angle view vision system (requires PC connection). This perspective allows the user to easily verify the proper backstop and blade positioning for various fiber diameters prior to cleaving.


In addition to the best cleave quality obtainable, this LD cleaver has an on-board LCD that provides continuous status updates and instructs the operator in the proper loading and cleaving sequence. The menu system enables the operator to easily create, modify and use up to ten cleaving programs, allowing efficient transitions between different fiber diameters.
