The PLC fiber optic splitter is based on planar Lightwave circuit technology and precision aligning process, dividing optical inputs into multiple outputs uniformly (1*N or 2*N).
Fabricated using silica optical waveguide technology for efficient optical power management.
Features small size, high reliability, wide operating wavelength range, and excellent channel-to-channel uniformity.
Widely used in PON networks to realize optical signal power splitting with high stability.
1x8 PLC splitter comes with 1 input and 8 outputs; cable lengths (0.6m, 1.0m, 1.5m) or customization available.
Available with SC/UPC, SC/APC, LC/UPC, LC/APC connector types.
Ideal for 8-port rack mount boxes, distribution frames, and outdoor fiber optic distribution boxes.

Frequently Asked Questions (FAQ)
What is a PLC fiber optic splitter?
A Planar Lightwave Circuit (PLC) splitter is an optical power management device that uses silica optical waveguide technology to distribute optical signals from one or two input ports to multiple output ports uniformly.
What are the common applications for 1x8 PLC splitters?
They are widely used in PON (Passive Optical Networks), FTTX deployments, CATV links, and general optical signal distribution in telecommunication environments.
Can the cable length and connector types be customized?
Yes. While standard lengths are 0.6m, 1.0m, and 1.5m, they can be customized. Connector options include SC/UPC, SC/APC, LC/UPC, LC/APC, and FC.
How does temperature affect the performance of the splitter?
These splitters are designed for high stability with an operating temperature range of -40°C to +85°C, featuring a very low temperature-dependent loss (typically ≤0.4dB).
What is the difference between splitters with and without connectors?
Splitters without connectors (bare fiber) generally have slightly lower insertion loss (e.g., 10.5dB vs 10.7dB for 1x8) because the loss from the connector mating is not included.
Are these products compliant with environmental standards?
Yes, all splitters follow strict curing and quality control methods and are fully ROHS compliant for environmental protection.
