The worldwide spread of mobile devices, such as smartphones and tablets using SNS, video streaming, etc., is causing an explosive increase in data traffic volumes. Mobile network base stations are configured using various methods, but the antenna radio section uses an optical fiber to connect the BBU an RRH passing via a general interface called the CPRI/OBSAI. The need for optical fiber fault finding and transport quality tests increases as the Mobile network environment becomes more advanced. Installing the 10G Multirate Module MU100010A/100G Multirate Module MU100011A and OTDR Module MU100020A/21A/22A/23A in the Network Master Pro MT1000A supports all-in-one optical fiber fault finding and transport quality tests. Using the MU100020A/21A/22A/23A, scratched or dirty connectors at fiber cable connections can be detected as fault locations from the excessive optical reflections to support fault finding and troubleshooting of Mobile optical networks. Additionally, work efficiency is greatly improved using the Fiber Visualizer function supporting Easy-to-Use/Easy-to-Report testing.
Generally, depending on the optical fiber measurement environment, OTDR measurements require multiple settings such as distance range, pulse width, measurement time, etc., making work difficult for technicians who do not generally use an OTDR. When performing Pass/Fail evaluation of an optical circuit for a report, a simple intuitive GUI is key to improving work efficiency.
The MU100020A/21A/22A/23A emphasizes easy-to-understand operability using three application measurement modes: OTDR Measurement, FTTA Measurement, and OLTS Measurement.

The MT9083 delivers full featured OTDR performance plus loss test set and quality of service measurement in a surprisingly small and lightweight package. At only 28.4cm wide x 20cm tall x 7.7cm deep and 2.6kg (5.7lbs), it is field portable, yet rugged enough to withstand the outside plant environment. When equipped with power meter and visual light source options, it replaces several, larger pieces of test equipment.
