The FD440 is fully field-portable and lightweight measurement systems. Separate transmit and receive units permit fast characterization of installed cables enabling optical networks to be efficiently mapped and upgrade options to be considered. The spectral loss option is particularly applicable for DWDM upgrade work.

Overview
The FD440 portable test instrument has been designed by PE.fiberoptics to provide accurate in-system chromatic dispersion measurement. It is the only field portable measurement system to measure chromatic dispersion and spectral attenuation using fully programmable wavelengths. The FD440 is the only field portable measurement system for chromatic dispersion and spectral attenuation using fully programmable wavelengths. The differential phase shift technique used by the FD440 allows direct dispersion measurements at user defined points throughout the full range of 1250nm to 1650nm. Ideally suited for dispersion characterization prior to upgrading a network the FD440 also is useful in implementing DWDM networks and dispersion mapping of installed fiber links. Expandable: The FD440 offers several broadband source options including extra high power (XHP) sources and sources specifically designed for testing in the 1620 nm range. A tunable laser source version, the CHROMOS11 is also available.
