Equipment Calibration & Maintenance

Stay compliant with industry standards by taking advantage of our full service calibration lab. All equipment is inspected, calibrated to NIST traceable standards, and verified to be in conformance with the manufacturers specifications. All calibration services include a calibration certificate. The turn around time is typically 7-10 days upon receipt of the equipment and payment for standard services.

Equipment that we currently calibrate and service

• OTDR’s
• Fusion Splicers
• Power Meters & Light Source
• Cleavers

*NIST TRACEABLE STANDARDS – What are they and why should I care?

It’s fairly simple but important. The NIST (National Institute of Standards and Technology) defines a measurement so that both the item being measured (your equipment) and their measurement is a match. In other words, your equipment is calibrated against the standards that are set by this federal agency. The calibration has been verified though an unbroken chain of documents.

What is an unbroken chain of documents? Your piece of equipment is compared to our piece of equipment which in turn was compared to a piece of equipment from the NIST which is within a stated tolerance. The NIST set the tolerance and it is correct. Our equipment was compared to the NIST equipment so we know ours is correct. Finally yours is compared to ours and found to be correct. That is an unbroken chain. This unbroken chain which is traced back NIST standard for accurate measurement is how uniformity is maintained.

Why should I care? You want to reduce the uncertainty in your measurements and increase your customer’s confidence in the information you provide them with in short the fiber you installed was installed correctly and has minimal loss.

Even better. We are ISO 9001-2015 Certified.
This important compliance indicates our company’s excellence in product quality and service. ISO (International Organization for Standardization) often calls for us to test instrumentation so we have a documented NIST certification. ISO is the world's largest non-governmental developer of standards.

All test equipment that makes a quantitative measurement requires periodic calibration!

A Good Fiber Optic Tool Makes the Difference

OTDR’s (Optical Time Domain Reflectometer) is an especially useful piece of test equipment used in the fiber optic industry. This particular piece of equipment will help you determine the quality of a fiber optic network. Integrity Quite simply, an OTDR tests the integrity of the cable. It will show you where there is an attenuation, splice loss or ad-ditional types of problems with your network. These problems could be anything from inadequate connections to a broken fiber. Send the Light This piece of test equipment has a laser that emits a pulse of light down the fiber. This light passes through the fiber and is reflected from different types of imperfections, splices, and also the end of the fiber itself. Detect A sensitive receiver in the OTDR detects the reflected/scattered light that has been sent back to the unit. The OTDR then detects the elapsed time from the launch of the initial optical pulse. An increase of scattered light means that the line is experiencing some attenuation. Reflections from the end of the fiber as well as a break or loss from connectors all contribute to this reading. Interpret As the light is reflected back it is shown as a function of dis-tance. The OTDR then gives you a record of the light that is reflected and backscattered against the time this has taken since the initial pulse. The unit interprets all this data which then tells you the location of any issues with the network. Calibrate Please remember your OTDR is an important piece of diagnostic equipment and must be calibrated at spe-cific intervals to ensure correct diagnostics.

POWER METER & LIGHT SOURCE is another important piece of test equipment in your arsenal. Determine This test allows you to determine optical loss. When you test the end to end performance of your optical fiber this equipment will get the job done. The way this is done is relatively simple. Light All you do is use your light source to send light down the cable. At the opposite end you have the power meter that reads the light you just sent. Loss The power me-ter then determines the amount of loss you have. The power meter and the light source can be purchased as a set or separately. When purchased as a single unit it is called an Optical Loss Test Set (OLTS). Dual Functionality This unit has a dual functionality, a power meter and a light source. When you attach one OLTS to each end of a fiber, the two units will perform a bi-directional, end to end loss measurements.

FUSION SPLICER When two ends of optical fiber are permanently welded together by an electrical arc this is known as fusion splicing. Avoid Reflection When you fuse these two ends together you want to do this in such a way that the light is not scattered or reflected back. If your splice is done correctly this will be minimized. When using heat shrink tubing, the splice and the immediate area surrounding the splice should be just about as strong as the untouched fi-ber itself. There are two important points to remember when dealing with a fusion splicer. Keep it Clean Always keep your equipment clean and calibrated. Keeping your fusion splicer clean and otherwise well maintained is vital to achieving a good splice. Electrodes, camera lenses and mirrors deserve special attention. Watch those Adjustments Just as important adjust your current and time parameters as little s possible. Adjust either the time or the current minimally and only one at a time. This will ensure the proper settings to make the best spice possible.

CLEAVERS Cleaving is the process of breaking or cutting of the fiber. Fusion splicing requires the use of a highly ac-curate cleaver. Precision The key word here is precision. Strong, low loss fusion splices begin with a good cleave. You always want to have a precise, perfectly flat end face. High end cleavers provide the end face required to prepare a fiber for fusion splicing. Perpendicular A good precision cleaver will produce a 90 degree cleave that is perpendicular to the fiber end face. It’s a pretty simple procedure. Here’s How Open the body, clamp the fiber into the cleaver, close the cover and slide the cleaver. You are done. Tip To further ensure accurate cleaves you may want to replace or ro-tate your blades ahead of the manufacturer’s recommended schedule.
