ACCESS Master MT9085 系列是一款紧凑型手持式一体化测试仪，用于执行光脉冲测试、光损耗/功率测量和光纤端面检测。它具有多种应用，从主干光纤（核心、城域、移动前传、移动回传）的安装和维护 （I&M） 到接入网络故障排除，例如引入电缆中断。
MT9085 除了保持以前型号使用硬键和旋钮的直观操作性外，还升级了 8 英寸彩色宽大的 LCD 触摸屏。Fiber Visualizer 功能也已进入下一阶段，一目了然地确认光纤传输路径。
光脉冲测试 （OTDR）
光脉冲测试可测量光纤传输损耗和光纤长度，并检测事件，例如光纤连续性中断。支持单模和多模光纤，并且该产品线包括对与测量环境匹配的各种波长的支持。易于使用的 Fiber Visualizer 功能使用两种类型的实时扫描（高速、高信噪比）来检查光纤连接和弯曲的状态，同时监控波形;以高精度（最大 46 dB 动态范围，0.8 m 盲区）检测光纤上的事件并测量损耗。出色的波形质量支持短距离到长距离的光学测量，包括 PON 和实时测量。
光功率/损耗测量
一体式 MT9085 系列具有内置光源以及功率和损耗测量功能，非常适合确认光纤安装状态和故障情况。
光纤端面检测
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)
The 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.
