Introduction and Applications
The KI6600 Series FiberSafe Microscope is a robust handheld tool for visual inspection of a fiber optic connector end-face. It is
fitted with red and infrared safety filters, and high-quality glass lenses. Easy to operate and ergonomically shaped, this
microscope is ideal for field, QA or laboratory use.
Inspection and cleaning of fiber connectors should be performed every time an optical fiber connector is mated, so every
technician needs easy access to a microscope. Failure to ensure connector end-face cleanliness is the most common cause of
problems in fiber systems, and can cause permanent damage to fiber connectors.

Getting Started
•Install a single AAA (alkaline or NiMH) battery. A low battery (0.9 –0.65V) is indicated by intermittent illumination flicker.
Illumination level is unaffected by battery voltage. If a rechargeable battery is used, it must be removed for charging
elsewhere. Alternatively, power externally using the supplied USB cable. When powered via USB, illumination of the
microscope is on permanently.
•Select a screw-on connector adaptor to match your application. The adaptor must match both the connector polish type,
e.g. PC or APC, and ferrule diameter, typically 2.5 mm or 1.25 mm. The unit comes with a 2.5mm PC Universal Adaptor.
See Optional Interchangeable Connector Adaptors section on last page for other available adaptors.
•To inspect a fiber connector end-face, push the connector ferrule into the microscope adaptor, so that it is positioned
against the end stop. If inspecting an APC connector using a Universal Adaptor, rotate the connector, so that end-face is
flat, or focussing will be poor. However, it is recommended to use APC adapter with specific connector type as a better
solution where possible.
For the case of MPO adaptor, adjust the screw attached to the adaptor to move connector ferrule laterally to inspect all
fibers on the ferrule.
•Press the front switch of toggle button to select coaxial illumination (see below). To select (green) oblique illumination (see
below), press and hold the front switch of toggle button. Coaxial illumination uses a white LED on the side of the scope
body. Pressing rear switch of toggle button will turn off instrument. For convenience and battery saving, illumination stays
on for about 2 minutes; however, timer is disabled if using external power for bench use.
•To focus, while holding the rubber eye cup to your eye:
- adjust the focus knob to achieve a clear image of the connector tip. When image is in focus, the centre of XY-alignment
wheel (right) will typically be positioned near the white arrow on the right of focus knob.
- adjust the X–Y adjustment wheels to centre the image.
If you find it difficult to locate and centre the image, do the following (much easier with a very dirty connector!):
- loose X-Y adjustment wheels and move them to find the edge of the connector
- from the edge of the connector, project to the centre of the image, which will be the centre of the connector, and rotate
X-Y adjustment wheels to move the image along projection path to this point.
•To illuminate a patch lead core, position and hold ferrule tip (at the unconnected end of patch lead) onto the white LED
located at the side of microscope, and use the coaxial illumination mode. See sample image in Fig. 1 below.
•For convenience, the microscope can be mounted on a standard camera tripod (Fig. 2 below), or a wrist strap fitted to assist
carrying.
•It is good practice to use the microscope with both eyes open, to avoid eye strain. The rubber eye cup helps this.
•To view and/or save microscope images on a computer, replace the scope’s eyepiece with a digital camera (optional, see
Optional Accessories section on last page) connectable to a computer via USB.
Illumination Explanation
The microscope has triple illumination capability, each with different attributes:
•Coaxial: White LED light hits the fiber end-face at right angle, providing the highest level of image details.
•Oblique: Green LED light hits the fiber end-face at an acute angle, which makes the fiber core readily visible, but allows users
to see only major defects and contaminants, with minimal training.
•Core: White LED light travels up the fiber core to show continuity or sub-surface fiber core defects.

Laser Safety Summary
The microscope is fitted with safety filters, which greatly reduce the risk of eye damage due to accidental exposure to red or
infrared light. Always observe eye safety procedures compliant with your company policy, relevant laser safety standards, and
safety practices.
NOTE: It is accepted safety practice to avoid viewing active optical fiber signals. In potentially risky situations, always check for
the presence of light before viewing, using a Ge, InGaAs or high power optical power meter set to its least sensitive practical
setting (often 850 nm).
This microscope is 100% eye safety tested during
production using traceable instruments to the
maximum input power, according to IEC 60625-
2 Ed. 3.2:
640 - 680 nm: 60 mW / 18 dBm (visible red)
680 - 1700 nm: Class 3B (infrared)
The IEC 60825 eye-safe emission limit is either Class
1 or 2. Sometimes it may be desirable to check filters
integrity. There are two safety filters installed-red and infra-red. The infra-red filter is integral with the coaxial illumination, so if
it’s physically damaged, the illumination will not work. Red filter integrity can be easily checked by pulling off the eyepiece. A
further check would be to perform an attenuation test using a large area detector against the eyepiece.
Pass/fail Acceptance Guidelines
Proper guidance on pass/fail criteria is beyond the scope of this manual, since it is likely to vary significantly.
The Standard ISO/IEC14763-3 Testing of optical fibre cabling specifies requirements and visual standards for connector end
face inspection with a microscope.
The standard and common industry practices recommend the following pass/fail acceptance criteria:
•Markings on the core or damage to the cladding close to the core are unacceptable.
•Slight scratches and small pits on cladding, away from the core, are acceptable.
•Cracks are not permitted in either core or cladding.
Care of Your Instrument
This is a precision optical instrument. Keep it clean, dry and do not drop. Avoid exposure to moisture or excessive vibration.
Objective and eyepiece lenses should be cleaned with a microfiber cleaning cloth. During prolonged storage, remove battery
to eliminate the possibility of acid leakage.
