Performance Comparison of Low Insertion Loss Splitter Remote Monitoring Type and Selection Guide
This guide focuses on two critical aspects of optical splitters that define FTTH performance: split ratios (how signals are divided) and splitting architectures (how splitters are deployed). In fiber-optic networks like FTTx and PON, PLC splitters are key components for distributing optical signals to multiple users. However, each splitter has complex parameters, including insertion loss, return loss, polarization-dependent loss, and uniformity. They have been used since the 1980s to create networks and provide the technology for today's passive optical networks used in fiber to the home. Planar Lightwave Circuit (PLC) splitters are essential passive devices in modern fiber-to-the-home (FTTH) networks. Although often viewed as a simple passive device, the choice of splitter type, split ratio, and connector interface has a direct impact on network performance, scalability, installation efficiency, and long-term operational cost.
