LDC-400 Large Diameter Fiber Cleaver


LDC-400 is a fully automated fiber cleaver that produces flat and angled cleaves on fibers ranging from 80 microns to 1.25 mm in diameter. This tension-and-scribe system marries the tensioning capabilities of our linear proof testers with precision diamond blade scribing technology to produce consistent low-angle cleaves with mirror-quality end-face finishes.

LDC-400 features programmable cleave tension, rotation angle and scribe conditions for cleaving circular fibers, polarization maintaining (PM) fibers and capillary tubes, and includes specialty processes for cleaving photonic crystal fiber (PCF). In addition, the system can be configured for cleaving non-circular fibers typically used in fiber laser systems. LDC-400 is an ideal companion to our GPX-3000 Series glass processing systems and our LFS-4000 large diameter fiber splicing system.
