The high port density optical switch family is designed for remote fiber testing in networks with large fiber counts or numerous FTTP service points, including PON, DAA, and DWDM systems. Scalable and high‑capacity, it enables rapid test port expansion for growing networks and supports remote testing, troubleshooting, and monitoring when paired with a VIAVI Remote Fiber Test System or Fiber Test Head. Available in 36, 48, 96, 144, or 192 ports within a compact 1/3‑width, 1RU form factor, the switches can also be cascaded, allowing a 192‑port unit to provide even greater expansion for large‑scale fiber infrastructures.
