GouMax’s small-form OSA modules with applications to test and measurement equipment are described below. The OSA product is designed and produced using GouMax’s proprietary micro-optics and voltage-controlled tunable filter technology. It measures optical spectrum of optical signals injected into the OSA device over the defined operating wavelength range. From the measured spectrum, critical channel parameters, such as channel power, wavelength, or OSNR, can be analyzed and reported.

GouMax single-band OSA modules support O-, E-, S-, C-, L-, and U-band operation within 1250~1650 nm range.

When used for test and measurement equipment, the embedded OSA module plays a role of OSA engine, integrated into customer's equipment. Customer will control the module and analyze the spectrum data using customer's algorithm.

The OSA module can be used as a standalone device. GouMax provides control software and GUI for data analysis.
