Attenuator Calibration service



What is an Attenuator?

Attenuator is a specialized instrument to measure specifications about optical fiber such as: break point, weld point loss, full line loss, converter loss, connector loss, output power, fiber diameter, scattering, fiber identification, continuity measurement ...

When an Attenuator is used to identify faults, such as fractures and optical reflectance attenuation, It is going to transmit a light pulse into the fiber, which then travels through the fiber. When the pulse meets point of failure (broken point), It will be reflected back or partially lost. The reflected signal will suffer a change in amplitude. Based on the measured pulse volume, pulse wavelength and pulse duration, the attenuator will determine the attenuation parameters, as well as cable length.

Attenuator Calibration procedure
In order to best serve the customers, engineers at EMIN Vietnam have developed the Attenuator Calibration procedure as follow:
Step 1, Prepare for calibration. In this step, standard instrument and the Attenuator that requires calibration are needed.
Step 2, Begin the calibration
- Outside Check: Check for scratches, rust, buttons, labels (still or lost), ...
- Technical check: Start the instrument, check the function keys for errors, mismatches, running operation, speed/switching ability ...
- Measurement check: Switch the equipment to test mode, set the appropriate measurement configuration, check quality indicators related to the publication of the manufacturer ...
Step 3, General handling

In the calibration process of Attenuator, high-precision, low-error, highly specialized, ... calibration equipment is needed to ensure fast, accurate, quality calibration.
After calibration, the analytical accuracy of the Attenuator is brought to evaluation.
