The EXFO FTB-5500B PMD Analyzer module is designed for ultra-long-haul and 40 Gbit/s applications. It provides you with the speed, accuracy and high performance you need to ensure high-quality network services. Particularly important in multichannel transmission and as rates reach 40 Gbit/s and higher, second-order PMD is derived from the measured PMD value. EXFO’s software provides second-order PMD delay and coefficient values for telecom fibers. These values allow you to characterize fibers and cables more precisely than simple PMD and better control the transmission quality of high-speed systems. The Exfo FTB-5500B has unique technology that allows for both the auto-correlation and cross-correlation to be known. Therefore, any spectral shape of source can be used. The auto-correlation peak is thus removed, and higher accuracy and resolution are obtained. PMD of 0 ps can be measured. In addition, a signal transmitted through EDFAs can be analyzed for total link PMD. Specifications. Wavelength range: 1260 to 1675 nm (O to U band). Measurement range: 0 to 115 ps. Sensitivity (Typical, for C band. May be increased with averaging. With the FLS-5800, the typical dynamic range is 47 dB.): –45 dBm. Measuring time: 4.5 s (for any PMD value). Absolute uncertainty (strong mode coupling), (ps) ± (0.020 + 2 % of PMD). Allows measurement through EDFA Yes (above 120 EDFAs).
