Calibration Services

Minimum Downtime, Maximum Performance

In keeping with accepted international standards, EXFO is committed to delivering high-quality services. Therefore, our definition of calibration is the one specified by the International Office of Weights and Standards, which states that calibration is a “set of operations that establish, under specified conditions, the relationship between values of quantities indicated by a measuring instrument and the corresponding values realized by standards”.

Calibration vs. Verification

Verification performed by independent calibration labs will only check if your unit is still within the manufacturer’s specifications. Unless the lab is equipped with instruments provided by EXFO, no adjustment can be performed.

When a unit is sent to EXFO for calibration, our process not only includes the comparison between the unit and the reference standard, but it also guarantees the best possible performance. After verifying the performance of the unit, as received by the customer, we will also make any necessary adjustments to ensure that, once it is returned, the unit will perform according to guaranteed specifications.
