The ACCESS Master MT9085 series is a compact handheld all-in-one tester for performing optical pulse tests, optical loss/power measurements, and optical fiber end-face inspections. It has a wide variety of applications, ranging from installation and maintenance (I&M) of trunk fibers (Core, Metro, Mobile Fronthaul, Mobile Backhaul) to troubleshooting Access networks, such as breaks in drop cables.
As well as keeping the intuitive operability of previous models using hard keys and rotary knob, the MT9085 has been upgraded with a wide, 8-inch, color, LCD touchscreen. The Fiber Visualizer function has also been taken to the next stage with at-a-glance confirmation of the optical fiber transmission path.
Optical Pulse Test (OTDR)
he optical pulse test measures the optical fiber transmission loss and fiber length as well as detects events, such as breaks in the fiber continuity. Both single mode and multimode fibers are supported, and the product line includes support for various wavelengths matching the measurement environment. The easy-to-use Fiber Visualizer function uses two types of realtime sweep (high-speed, high S/N) to check the status of fiber connections and bends while monitoring the waveform; events on the fiber are detected with high accuracy (46 dB dynamic range max., 0.8 m dead zone) and loss is measured. The excellent waveform quality supports short to long distance optical measurements, including PON and realtime measurement.
Optical Power/Loss Measurement
With a built-in light source and power and loss measurement functions, the all-in-one MT9085 series is ideal for confirming the status of optical fiber installations and fault conditions.
Optical Fiber End-Face Inspection
Optical fiber end-face inspection uses an external fiberscope option (sold separately) to display the condition of the optical connector ferrule end face on the screen of the MT9085 main unit. Optical fiber end-face inspection is important because not only do dirt and scratches on the ferrule face have a major impact on optical fiber circuit transmission quality, but they also prevent accurate optical pulse tests and measurement of optical loss and power.
