Large-scale optical fiber wiring for 128 × 128 PLC switch system with fiber physical contact connectors and optical fiber circuits

摘要

The increasing number of channels in DWDM systems has led to the need for large-scale fiber wiring in the system racks. We have developed a novel optical wiring system with a fiber physical contact (FPC) connector for 16 fibers and an optical fiber circuit for 256 × 256 cross wiring. This optical fiber wiring system is designed to install fiber efficiently and without congestion. We used our optical fiber wiring system to construct a 128 × 128 switch system with 1 × 128 planar lightwave circuit (PLC) type thermo-optic switches (TOSW) that had to be capable of handling more than 10000 fibers while offering easy installation and an orderly layout.
