Planar Lightwave Circuit (PLC) optical splitter is an integrated waveguide optical power distribution device based on quartz substrate. It is one of the most important passive devices in fiber optic links, a fiber optic convergence device with multiple input ends and multiple output ends, especially suitable for connecting central office and terminal equipment in passive optical networks (EPON, GPON, BPON, etc.) and realizing optical signal splitting. The micro steel tube type splitter is the primary packaging of the splitter, which may be re-packaged into subrack type, plug-in type, tray type, etc., or used in any optical network termination box.
Loss is insensitive to the transmitted light wavelength, meeting the transmission needs of different wavelengths
Uniform light splitting, enabling even distribution of signals to users
Compact structure and small size, allowing direct installation in various existing cross-connect cabinets
No need for special design to reserve large installation space
A single device has many splitting channels, up to more than 32 channels
Low cost for multiple channels; the more splitting channels, the more obvious the cost advantage

Notes: 1. Applicable to devices with all integrated components;
2. All parameters are tested including connectors, under the condition of λ=1310/1550nm.
3. The test wavelengths for splitting uniformity are 1310nm, 1490nm, and 1550nm. For the wavelength ranges of 1260nm-1300nm and 1600nm-1650nm, the splitting uniformity index is increased by 0.5dB on the basis of the above indicators.
