Why Couldn’t We Just Use Multi-Mode Fiber in OCS? (Part 2: 2D FAUs and Architecture Fiber Counts)
In Part 1 of this technical deep dive, we explored the physical constraints of Optical Circuit Switches (OCS) and why multi-mode fiber (MMF) causes unacceptable insertion loss (5-10dB). As established, single-mode fiber (SMF) is non-negotiable for OCS. But how are these micron-scale single-mode fibers physically arranged, aligned, and integrated into high-density OCS hardware? In Part […]
