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.
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.
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.
