## What is GVIS?

The GVIS 300 and GVIS 400 provide an easy-to-use video fiber connector inspection system. Their unique focus system eliminates the need for users to place their hands in the same position each time for effective focus control. To inspect the backplane connector, the user simply inserts the probe into the connector adapter. To focus, turn the entire probe 1/4 to 1/2 turn for complete focus range. No longer is it necessary for the user to keep one hand on a focus wheel.
The GVIS 300 includes a bright 3.5 inch LCD with precision optics to provide a FOV (field of view) of 630 μm by 440 μm. Extended use lithium-ion batteries provide 8 to 10 hours of continuous use. When charging is necessary, the included “smart AC charger” charges the battery in 3 hours and allows the unit to continue to operate during the charging cycle.

The GVIS 300 monitor is supplied in a padded nylon case. Both the probe and monitor are transported in a hard carry case that also includes the charger, extra adapter tips, and cleaning aids.

The GVIS 400 system consists of a GVIS 400-HDP high definition probe that has an FOV of 860 μm by 640 μm. The GVIS 400 probe can be plugged into the USB port of a personal computer for use with the GVIS software. The probe can also be plugged into the GPAD 250 portable access device. This industry leading field of view capability allows the user to identify contamination outside of the contact zone that may migrate to critical zones due to vibration and other environmental conditions.

The GPAD 250 generates a wireless hotspot that can be used to interface to smart phones.
