Mini Tube PLS Splitter
Mini Tube PLS Splitter
C-LIGHT Mini Tube PLC Splitter is an ultra-compact, tube-packaged planar lightwave circuit (PLC) splitter designed for high-density fiber-optic networks. Utilizing PLC technology, it splits input optical signals into multiple outputs (e.g., 1×8, 1×16) via a miniaturized waveguide structure, supporting wavelengths of 1310/1490/1550 nm with low insertion loss (≤0.3 dB), high uniformity (≤0.8 dB), and robust environmental stability. Its compact tubular design (e.g., Φ2.0×54 mm) eliminates the need for additional enclosures, enabling direct integration into fiber patch panels, junction boxes, or terminal equipment for space-saving and simplified cabling. Ideal for FTTH (Fiber to the Home), 5G fronthaul networks, and dense data centers, it ensures flexible and efficient fiber resource management.
