ZS1000-B
5-IN-1 MINI OTDR
The Signal Fire ZS1000-B OTDR is a compact, handheld optical tester designed for fast and accurate fiber diagnostics. It combines five essential functions in one device: OTDR, optical power meter, stable light source, VFL (red light source), and an LED flashlight. It supports live testing. With a test range from 100m to 80km, an attenuation dead zone of 12m, and an event dead zone of less than 3m, it delivers precise measurements for fault location, fiber length, and loss analysis. Its one-click auto test function makes it easy to operate, even for beginners. The device supports 8000 sampling points and features a USB-C port and intelligent OTDR simulation software for detailed event visualization. Ideal for field technicians handling maintenance, construction, or small-scale fiber projects.
Professional in fast rapair
An ZS1000-B OTDR helps quickly find where a fiber signal problem is. It shows the exact point of loss or break and makes it easy to locate which splicing box has the issue. This saves a lot of time and avoids checking every connection manually.
Support live test
Even with live test, it will not caise damage to the optical components and strictly protect its own precision part.
