Details

The FOT-920 MaxTester Automated Loss Test Set is the unit of choice for field technicians in network installation and maintenance. This unit integrates a fully automated bidirectional loss test set (OLTS), a light source and the Ultra-High-Power™ power meter with useful options, including a full-duplex digital talk set,visual fault locator and optical return loss test set, to create versatile combinations.

High-Fiber-Count Installation

The FOT-920 gives you the edge when it comes to high-fiber-count installation. First, when doing a large volume of testing, the return on your investment takes less than a year. Second, the FOT-920 reduces the time you spend testing, training and in the field, making it ideal for outside plant applications.

OC-48 and OC-192 Systems

Due to their high modulation rates, lasers used to transmit at OC-48 and OC-192 speeds are highly sensitive to ackreflection. When installing networks designated to transmit at these speeds, measuring backreflection is a must to ensure proper stability of the lasers and their central wavelength.

Maximize your testing capacity with the FOT-920 MaxTester.

Bidirectional, Dual-Wavelength Testing and Professional Reports

EXFO understands that your time is valuable; that’s why the FOT-920 features the patented FasTesT system. FasTesT automatically measures single-fiber loss in both directions, at two wavelengths, in less than 30 seconds. To speed up the reporting process, the FOT-920 stores all test results in its non-volatile memory; later, you can file test data according to your own cable identification scheme. Create more extensive reports, including user and test location information, with ToolBox 6 software (included). Download, print or store results on a computer hard drive.

Optical Return Loss (ORL)

With widespread use of OC-48 and OC-192 transmission systems, bandwidth is essential. Flawless operation of high-data-rate systems depends on measurement and control of backreflection or optical return loss (ORL).

ORL can affect transmissions by

Destabilizing DFB laser sources
Interfering with high-frequency analog signals
Increasing the bit error rate in high-frequency digital signals

Simply measure ORL with the FOT-920 using the optical continuous wave reflectometer (OCWR) method.

Talk Set Communication and Visual Fault Location

Coordinate end-to-end testing between remote sites with a fiber-optic talk set. The FOT-920 features an optional, full-duplex digital talk set for crystal-clear voice transmission. If the talk set cannot be used, the unit can send preset or preprogrammed messages via the fiber under test.

Perform end-to-end identification or pinpoint breaks, bends, faulty connectors, splices and other causes of signal loss over a distance of up to 5 km. At the exact fault location, the visual fault locator (VFL) emits a red glow that is visible through most yellow jacketed fibers.

Maximizing Testing Efficiency

The FOT-920 MaxTester is a compact, portable test tool that stands up to virtually any field environment. It features a splashproof casing, durable shoulder strap and long-life rechargeable battery. The backlit alphanumeric display quickly and easily shows you results and messages under any light conditions.

Wide-Ranging Compatibility

FasTesT, a rapid, automated dual-wavelength, bidirectional loss test, can be carried out with the following products: the FOT-920 MaxTester, an automated loss/return loss test set, and the FTB-3920 MultiTest Module. Obtain crystal-clear voice communication using any two of the following products: talk set options for the FOT-920 MaxTester, the FTB-1400 and the FTB-3920 MultiTest Modules, as well as the VCS-20A Multi-Function Fiber-Optic Talk Set. The FCD-10B Clip-On Device can be attached to a non-terminated fiber for communication between two talk sets.

Data Management

With increasing fiber deployment in Telco and CATV networks, busy fiber installation companies sometimes hire subcontractors to perform installation jobs. But subcontractors need to provide test documentation to show that a job meets specifications.

Now, subcontractors who use the FOT-920 can produce quality documentation efficiently. Thanks to the data logging and management features of the FOT-920, users can archive results and download information through the RS-232 port to a PC for professional analysis and report generation.
