Optical Time Domain Reflectometer

This fully featured OTDR with tablet-inspired design combines singlemode and multimode fiber testing in a dedicated and compact quad unit to allow everyday field testing in access networks, data centers and private enterprise networks.

The lightweight and compact SmartOTDR speeds and optimizes field testing of metro and access networks—with a tailored OTDR interface and automatic analysis that any technician can understand. With SmartOTDR, generic or user-defined setup configurations eliminate setup errors and maintain results consistency. One-touch operation and a single results window ensure fast and easy measurements, while robust wireless connectivity options increase productivity anywhere.

Deviser AE3100A Single Mode OTDR Instrument's 4th generation OTDR, field-portable, a giant leap forward in fiber-optic measurement performance and utility.

From Deviser Instruments' 4th generation of OTDR, the fieldportable AE3100 marks a giant leap forward in fiber-optic measurement performance and utility. Single-mode models A through F can test the 1310nm and 1550nm wavelengths with dynamic range up to 45dB, while multimode models M through EM add quad-λ functionality at up to 43dB. Featuring intuitive touchscreen controls and real-time data analysis, the AE3100 is the ideal test instrument for constructing, deploying, maintaining, and authenticating FTTx networks - as well as verifying access networks. Multiple models and configuration options ensure your unique measurement needs are covered.

Testing FTTH network is similar to other OSP testing but the splitter and WDM add complexity. FTTP PON networks can be more complicated than simple OSP links, with WDM couplers, PON splitters, etc. in a single link, so complete testing can include some components and installation issues not familiar to the usual OSP tech. PON couplers add high loss, WDM couplers have different performance at different wavelengths and connector reflectance, not a problem in most systems, can be a problem in short links typical in FTTx. Many FTTx systems use APC (angled PC) connectors to reduce reflectance so test cables for both OLTS and OTDR need to have matching connectors.

    However, once installed,  users on a live network means testing cannot disrupt service. Thus testing may be as simple as checking power at the ONT on the subscriber’s house with a calibrated fiber optic power meter or just seeing if the ONT has a “green” connection light! The ONT at the home usually has some intelligence that can be accessed from a remote location, allowing a service tech to initiate a loopback test to verify connections at any user. If only one user has a problem, a service tech is then sent there, while if all users are down, the tech is sent to the central office.

   As with most fiber optic links, troubleshooting requires knowing the architecture of the system, expected link losses and optical signal levels and typical problems that may be encountered. As always, we emphasize the importance of having documentation on the system before testing and troubleshooting.

JDSU OTDR VIAVI OTDR New network architectures (PONs or passive optical networks) have been developed that allow sharing expensive components for FTTH. A passive splitter that takes one input and broadcasts it to as many as 32 users cuts the cost of the links substantially by sharing, for example, one expensive laser with up to 32 homes and only requiring an inexpensive laser at each home. However, this architecture changes the methodology of testing the complete installed cable plant and links for proper operation. Of course, individual links are tested as usual, it is the PON coupler that creates the difference.
