Overview

The ACCESS Master MT9085B-057 is the Enhanced Dynamic Range (B-type) model of the Anritsu MT9085 series configured with a three-wavelength single-mode OTDR module at 1310, 1550 and 1625 nm. Anritsu positions this wavelength set for maintenance work that uses macrobend analysis, with a typical dynamic range of 40/39/38 dB and an event dead zone of 0.8 m (typ.).

Like the rest of the MT9085 series, the unit is a compact handheld all-in-one tester for optical pulse tests, optical loss and power measurements, and fiber end-face inspection. It covers installation and maintenance of trunk fibers (core, metro, mobile fronthaul and backhaul) as well as troubleshooting of access networks, such as breaks in drop cables.

Operation

The instrument has an 8-inch color LCD touchscreen and keeps the rotary knob and dedicated hard keys of earlier ACCESS Master models. The Fiber Visualizer function shows fiber events such as splices, connectors and PON splitters as schematic icons, with Pass/Fail evaluation of loss and reflectance. Two realtime sweep modes, high-speed and high S/N, help locate fiber bends while watching the waveform. Manual analysis uses four markers with the two-point and LSA methods.

Power, loss and inspection

A stabilized light source and an optical power meter are built in as standard and share the OTDR port. Optional dedicated power meter ports (options 004, 005, 007) add optical loss test set measurements, and option 002 adds a visual fault locator. With the external G0306C Video Inspection Probe, the unit inspects connector end faces and evaluates Pass/Fail to IEC 61300-3-35.

Data handling

Traces are saved in Telcordia SR-4731 (.sor) format, up to 50,000 traces in 1 GB of internal memory. Data can be transferred over USB memory, USB cable, or WLAN or Ethernet through USB adapters. The unit can be controlled remotely through a web browser GUI or remote commands, and it produces PDF reports.
