The OTU‑5000 Compact Fiber Test Head enables remote fiber testing and automated monitoring using OTDR and optical‑switch technology. It continuously monitors multiple fibers anywhere in the network, supporting up to 48 fibers of 100 km or more while occupying only one‑third of a rack unit. The system scales up to 2304 switch ports, provides secure HTTPS web access, and runs on a ruggedized Linux OS. With dual power feeds, low power consumption, and in‑service monitoring capability, the OTU‑5000 helps service providers accelerate service delivery, reduce costs, and ensure rapid fault detection across compact, space‑constrained deployments.
