Product Description - Handheld OSA

Optoplex’s handheld optical spectrum analyzer (OSA) is the first “smart” – inspired by Android smart-device – handheld OSA in the industry. The OSA is equipped with an Android tablet for data processing, analysis, display and communications.

The Android tablet is a detachable unit which is click-mounted on the base (optical engine). The Android tablet communicates with the optical engine via Bluetooth when it de-attached from the handheld base. This feature provides the users a great flexibility when working on field or in an environment where the point of the network to be monitored/serviced has limited access.

Optoplex’s OSA is based on tunable-filter technology that offers high performance, fast scanning speed and compact in size. A wide selection of the OSAs is available with different performance specifications and wavelength coverage to meet your demanding applications.

In addition to the standard OSAs, as shown in the Specification-tab, a high spectral resolution design will be released soon. The high resolution OSA provides a spectral resolution as small as 15pm in C-band or C+L band. High spectral resolution designs for other wavelength coverage, such as O-Band, Full-Band, please contact Optoplex for details.

Key end-users of the handheld OSA in FOTE market include telecommunication companies and carriers, enterprises, cable television service providers, government and defense, fiber optic component and cable manufacturers, and independent research laboratories.
