Fused tapered optical splitter 90 10 are primarily used in fiber optic communication systems, CATV, FTTH, and fiber optic sensors. They are manufactured by fusing and stretching multiple optical fibers, using a tapering process to monitor the splitting ratio in real time. This creates a single-input, multiple-output splitting structure, with a splitting ratio that can be flexibly adjusted between 1:99 and 50:50. Welcome OEM ODM 1×2 SC fiber optic couplers from Yingda.
Yingda’s 1×2 fiber optic splitters offer flexible splitting ratios, customizable to any ratio optical coupler types between 1:99 and 50:50, supporting both unequal and equal power splitting, making them suitable for asymmetrical power distribution scenarios. Their low insertion loss and polarization-dependent loss also reduce system optical power loss, ensuring signal transmission stability. With low raw material costs and short production cycles, they are particularly well-suited for large-scale customized orders. Furthermore, mass production and highly precise cost control, Yingda fused coupler are hot popular due to its lowest fiber optic coupler price based on the highest quality.
