10 2 Feature Overview The VFS 2 is a small extremely versatile Video Fiber Scope designed for the inspection of fiber optic connectors and couplers. The VFS 2 retains the superior image quality associated with Noyes inspection products. The unique optical-knuckle allows the user to orient the VFS 2 Probe head in virtually any direction. This feature allows the user to view connectors that may be located in tight or difficult locations. With a Probe head length of less than 8 cm (3.25 ), access into crowded/ cramped quarters becomes a reality. The VFS 2 resolves ¾ micron scratches keeping with our standard of quality end-face images. This unit is designed for one-handed operation and with the optical-knuckle feature, the unit is equally easy for both right and left handed individuals. The new precision adapter tips for the VFS 2 Inspection Probe ease getting fiber images in the viewing area. These tips ensure the optics will view into the alignment sleeve, thus simplifying centering the fiber. An adapter tip must be left on the Probe at all times to protect the objective lens. The VFS 2 Inspection Probe may be paired with the VFS 2 high-resolution 3.5 (diagonal) Display or the VCP 1 Video Capture Port. The VFS 2 Display is a compact, portable unit that provide hours of continuous operation as well as rechargeable battery. The VCP 1 Video Capture Port allows the user to inspect fiber optic end-faces and capture viewed images on a PC. The VCP 1 simply attaches via a standard USB A plug connector to a computer and offers plug and play installation. With the supplied easy-to-use software, fiber end images can be saved and organized for analyzing, printing, and archiving.

11 To ensure proper operation, it is important to keep all optical connections and surfaces free from dirt, oils, or other contaminants. Proper cleaning techniques must be performed on fiber connectors, connector adapters, and optical ports. Refer to the section on maintenance for more information on cleaning methods. Always replace protective dust caps. Required Accessories The VFS 2 Inspection Probe requires an adapter tip that matches the connector type to be inspected. Adapter tips for all standard connector types are available. For an up-to-date list of adapter tips contact Noyes, or visit our web site at (click on Products > Noyes Test & Inspection > Accessories & Services). A supply of cotton tipped swabs (single or double ended) and commercial lens cleaner is recommended for cleaning the optical port on the Probe. Also, a can of filtered compressed air is useful for blowing contaminates out of connector adapter tips. For cleaning connector end-faces on test jumpers and in fiber frames or adapters, Noyes recommends using our exclusive FCC2 non-hazardous cleaning fluid and CCT molded cleaning tips. CCT cleaning tips and FCC2 cleaning fluid may be combined into FCP1 fiber optic cleaning kits. Noyes offers a complete selection of FCP1 cleaning kits for field cleaning.

28 Section 4: General Care and Maintenance 20 General Care The VFS 2 Inspection Probe is a precision optical device. As such, there are certain parts of the Probe that cannot be protected from abuse due to the small geometry required to interface with modern fiber optic connectors. The VFS 2 should be protected from accidental drops at all times. A drop on the tip end of the Inspection Probe can cause damage, which would prevent use of the Probe. Drops in other areas can lead to misalignment or damage as well. If the fiber end-face image appears to be distorted or is off the display screen, the unit should be returned to the factory for repair and/or calibration. Lens Care Contact with the small lens at the end of the Probe lens tube should be avoided. Adapter tips should be installed by gently sliding over the end of the lens tube as mentioned earlier. This action will not harm the lens. If the face of the small lens becomes contaminated, the image quality will be degraded. The lens must be kept free from dirt or other contaminants. It should be cleaned as needed using the instructions on the following page.! CAUTION! Remove Probe power for the following procedures.

29 To inspect the lens 1 Hold the VFS 2 Probe at an angle to room lighting. 2 Examine the lens with a magnifying glass. 3 If the lens surface does not appear to be clean and free of fingerprints, dust, or other contaminants, it should be cleaned. To clean the lens To access the lens, first remove the adapter tip that may be installed. Lens removal is not recommended. 1 To remove the installed adapter tip, twist it with a counterclockwise motion as viewed from the adapter tip end. 2 Gently slip the adapter tip off the end of the internal lens tube. 3 Using a double ended cotton swab (such as a Q-tip) or two single ended swabs, apply a single drop of lens cleaner to one end of a swab. Touch it to the lens, apply gentle pressure and rotate gently several times. 4 Immediately, use the dry end of a swab to repeat the action. This cleans the lens and removes remaining moisture. 5 Using a can of filtered compressed air (held vertically), blow out any contaminants from the adapter tip 6 Once completed, replace the adapter tip over the internal lens tube being careful not to contact the small lens opening. Twist the adapter tip clockwise in order to screw it into the end of the VFS 2 Probe. Finger tighten only! 21
