Description
The GVIS 300 and GVIS 400 provide an easy-to-use video
ber 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 (eld 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
denition probe that has an FOV of 860 µm by 640 µm. The
GVIS400 probe can be plugged into the USB port of a per-
sonal computer for use with the GVIS software. The probe can
also be plugged into the GPAD 250 portable access device.
The GPAD 250 generates a wireless hotspot that can be used
to interface to smart phones.
The GVIS 300 and GVIS 400 are supplied with a universal
2.5mm tip and a SC bulkhead adapter. Optional adapters for
most commonly used connectors are available.

GVIS 300 Probe and GVIS 400-HDP Probe
1. Adapter Tip Ring – Adapter tips allow the GVIS 300 and
GVIS 400 to access either the bulkhead panel connec-
tor or the actual connector end if access is available. The
GVIS 300 and GVIS 400 are supplied with two adapters,
the SC bulkhead adapter and a 2.5 mm universal adapter
tip to allow inspection of any 2.5 mm ferrule connector
(SC, ST, or FC).
To connect the appropriate adapter tip, place the tip on
the end of the probe, being careful to screw the adapter
to the adapter tip ring completely and nger tight only.
Do not hold or turn the focus ring while attaching the
adapter tip. For bulkhead adapters it is helpful to align
the key of the adapter tip to the center position facing the
user.
2. Focus Ring – Two focus methods are used to adjust the
image while using the GVIS 300 and GVIS 400. The rst
technique is used when using any of the universal tips for
direct connector inspection. To focus, insert the connec-
tor into the adapter tip and adjust the image by turning
the focus ring with your thumb.
To focus on the bulkhead connector surface, these probes
use a unique focus system by using specially equipped
adapter tips. These bulkhead tips include keyway devices
to lock the GVIS probe into the bulkhead under inspec-
tion. To focus on the bulkhead, simply insert the bulkhead
adapter tip into the bulkhead and rotate the probe slightly
in either direction for full focus control. The probe may be
held anywhere while rotating, allowing for much easier
focus control.
3. Probe Body – The probe body houses the optical inter-
face, camera system, and lighting system. The probe
body contains no user-serviceable devices inside the
housing. Refer to the maintenance section for proper care
of the optical interface at the tip of the probe.
GVIS 300 Monitor
4. Display Case – The display case includes the 3.5 inch
LCD display, battery, and control features to display the
required image. No user serviceable components are
found inside.
5. Conn/Probe – This control button is for possible future
functionality only. If the button is inadvertently pushed,
push it again so that the display toggles back to the active
probe display.
6. Probe Input – Insert the probe connector to the connec-
tor port located on the side of the GVIS 300 display case.
Power to the probe is automatic and will remain powered
while connected. To conserve battery use, remove the
probe from the display case during periods of inactivity.
7. Brightness Control – Adjust brightness with the up/down
arrow buttons. (The GVIS 300 has a default position of
two positions below the brightest possible image.) This
brightness control allows the user to discern defects with
greater ease.
8. AC Charger input – If the GVIS 300 display does not
illuminate the screen when powered on, then the battery
must be charged. To charge the battery and simultane-
ously use the GVIS 300, insert the AC charger connector
into the port on the lower left side of the display case.
Total charge time is approximately 3 hours. A green LED
on the charger indicates a fully charged battery. While
charging, this LED remains red.
9. Power On – This green LED indicates that power is avail-
able to the LCD and probe. During low battery conditions
this LED remains in the off position.
10. USB Port – Connect the accessory USB cable to the USB
port on the GVIS 300 monitor and then to a USB port on a
personal computer to view the image in the GVIS soft-
ware. An image can then be viewed and saved within the
GVIS application.
11. Power – Enable power to the GVIS 300 display by press-
ing the power control button. Pressing this button while
the unit is on powers the unit OFF.

GVIS Overview
Grading the Fiber End
GVIS allows you to grade a ber end face in two ways, automatic grading and technician (manual) grading.
Automatic grading requires a Greenlee GVIS 400-HDP probe. To perform automatic grading, the technician
connects the ber to the GVIS 400-HDP, focuses the image, and presses the Analyze button. The Greenlee
software performs and reports the analysis by comparing defects to the IEC 61300-3-35 2009 specication.
See “Automatic Analysis” in the “Performing a Test” section for more information.
A GVIS 400-HDP or GVIS 300 can be used for the manual graded method. For manual grading the technician
connects the ber to the probe, focuses the image, and grades the ber end by visually inspecting the image.
See “Manual Grading” in the “Performing a Test” section for more information.

Focus Bar
The blue focus bar is located below the ber end image on the Main tab. It is visible when a live image is
displayed and the image is not totally blurred. It is an aid to help focus the image. When the focus ring on the
Greenlee probe is rotated and the image becomes more focused, the red peak bar stays at the best focus
achieved. Each time a new peak is reached, the image associated with the peak is saved in a temporary buffer.
If the image becomes unfocused again after a peak is reached, the peak focused image is still saved. When the
Analyze button is pressed, the best focused image is used – not the image displayed at the time the Analyze
button was pressed. This helps to ensure the best focused image is used for the analysis.
