Until now, installing and maintaining optical networks required technicians to carry a variety of equipment which was not only cumbersome, but also expensive. Hearing this common complaint, Anritsu engineers have developed their new line of MT9083 ACCESS Master OTDRs. The MT9083B test sets are designed to make your measurement experience simple and error-free with true one-button fault location, pass/fail classification, automated file saving and naming and even a macrobend detection feature for identifying installation issues.  They feature multiple wavelengths and options to satisfy any network testing requirement: access or metro, FTTx or LAN...all without straining your budget.

For customers installing and maintaining metro area or core networks, the ACCESS Master offers an automated fiber construction application and multiple wavelengths including specialty applications such as 1383 nm for certifying legacy fibers for CWDM upgrades.

For FTTx networks, the MT9083 series provides both optical testing for optical splits up to a 1x128, plus quality of service (QoS) verification via the IP testing option. With the IP option, continuity, download speed, throughput and frame loss of Gigabit Ethernet links can be verified up to full line rate. It also features a unique way to troubleshoot live PON based, FTTx networks without additional costly and complicated external filters.

Additional features include an integrated light source and power meter plus options to customize the unit including higher range power meters, visual fault locator (VFL) and connector inspection microscope to ensure complete network evaluation with a single tool.
