Description
Overview
GAOTek fiber fusion splicers are type of optical power management device that is fabricated using Fused Biconical Tape technology. It features small size, high reliability, cheap cost and good channel-to-channel uniformity and is widely used in PON networks to realize optical signal power splitting. Rollball provides whole series of 1xN and 2xN splitter products that are tailored for specific applications. All products meet GR-1209-CORE and GR-1221-CORE. Rollball offers both tree and star type inline couplers/splitters. They provide a reliable solution to split/combine signals. The splitting ratio ranges from 1×2 to 1×4 ports for tree couplers, and from 2x2up to 4×4 for star couplers. Available in single, dual, and triple wavelength windows (1310 nm or 1490 nm or 1550 nm).Â
