Overview

The ACCESS Master MT9085B-053 is the general-purpose 1310/1550 nm single-mode configuration of the Enhanced Dynamic Range MT9085B model in the Anritsu MT9085 series. The series is a compact handheld all-in-one tester for optical pulse (OTDR) tests, optical loss and power measurements, and optical fiber end-face inspection, used for installation and maintenance of metro, long-haul and PON-based FTTx networks.

OTDR measurement

The OTDR measures fiber transmission loss and length and detects events such as splices, connectors, splitters and breaks. The Fiber Visualizer function displays events as schematic icons with distance, loss and reflectance Pass/Fail evaluation. Two realtime sweep modes, high-speed and high S/N, help locate fiber bends and check connections while the waveform is monitored. PON networks with up to 1 × 128 branches can be analyzed.

Power, loss and end-face inspection

A stabilized light source and an optical power meter are built in as standard through the OTDR port. Optional dedicated power meter ports support optical loss measurements with a single tester, and a visual fault locator option shows light leaking at fiber breaks. Connected to the external G0306C Video Inspection Probe, the unit inspects connector end faces with automatic Pass/Fail evaluation to IEC61300-3-35.

Operation and data handling

The 8-inch touchscreen works together with a rotary knob and dedicated hard keys, and the pressure-sensitive screen accepts input while wearing work gloves. Measurement data can be saved in original formats (.sor, .vipi), as .csv files or as PDF reports, and shared with a PC over USB, WLAN or Ethernet using external adapters.
