ABS Box Splitter (PLC Splitter) is an integrated waveguide optical power distribution device based on quartz substrate. It has the characteristics of small size, wide operating wavelength range, high reliability and good uniformity of splitting. It is especially suitable for passive. It is one of the most important passive components in optical. A PLC splitter (Planar Lightwave Circuit splitter) is a device used in fiber-optic networks to split a single optical signal into multiple signals, allowing a single fiber-optic cable to serve multiple users or devices.
