Equipped with advanced fiber measurement software and high-resolution camera for real-time process viewing, Models GPX-3800 and GPX-3850 use proprietary filament fusion technology to create splices and fiber-based fused components such as combiners, tapers, mode converters, couplers, and end caps. GPX-3800 processes fibers with diameters as large as 1.25 mm, while GPX-3850 processes fibers up to 2 mm. In-situ cleaving on both models handles fiber diameters up to 400 microns.
