1×4 PLC Splitter
A 1×4 PLC Splitter (Planar Lightwave Circuit Splitter) is a passive optical component designed to divide one optical signal into four equal output signals while maintaining excellent optical performance and reliability. Widely used in FTTH networks, PON systems, CATV, data centers, telecommunications infrastructure, and optical distribution networks, the 1×4 PLC splitter enables efficient signal distribution with low insertion loss and high uniformity.
As a professional 1×4 PLC splitter supplier, we provide high-quality PLC splitters that comply with international standards and are suitable for indoor and outdoor fiber optic applications. Our PLC splitters are available in multiple package types, including bare fiber, mini module, ABS box, LGX cassette, rack-mounted, and customized configurations.
What is a 1×4 PLC Splitter?
A 1×4 PLC splitter is an optical power management device fabricated using silica optical waveguide technology. It accepts one optical input and distributes the optical signal evenly to four output ports.
Unlike FBT splitters, PLC splitters offer:
- Wider operating wavelength range
- Better channel uniformity
- Lower polarization dependent loss
- Higher reliability
- Compact structure
- Superior performance in PON networks
These advantages make the 1×4 PLC splitter the preferred solution for modern fiber optic communication systems.
