Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.

Notice
The EDFA slot module of FOTS system with built-in power booster EDFA module offers a special function that is able to change the optical signal amplification feature variously, which is followed by user’s driving embedded pump LD freely. The output power of eash pump LD can be controlled separately by the program that is set up by user. When an optimum optical signal amplification particularity is needed, it is made up so that it can be materialized by choosing the Default mode provided along with User mode. More stable application of EDFA is possible through the monitoring of the factors such as in/out signal power, gain, alarm status and pump LD enabled by the application of FPGA processor which makes high speed driving possible. It is also set up that user’s present-time monitoring and control through LCD monitor of system main frame or GUI display for remote control can be possible. Through optimization of amplifier gain, noise figure, and saturated output power, this EDFA module will expand test capabilities in systems, components or sub-assembly manufacturing.
