When building and inspecting optical communication networks, a measurement system consisting of a light source and optical level meter (or power meter) is used to evaluate fiber condition and proper connections.
The light source is placed at one end of the communication channel being tested, and the signal transmission is evaluated from the other end.
Metrosert’s current calibration range for level or power meters includes:
Nominal wavelengths: 640 nm, 850 nm, 1300 nm, 1310 nm, and 1550 nm
Measurement range: 1 nW to 4 mW (-60 dBm to 6 dBm), depending on wavelength
Accuracy: 0.5 dBm
- For sources, the measured parameter is output power at wavelengths from 250 nm to 20000 nm (accuracy 5%)
- For LED sources, spectral shape is also measured in the wavelength range of (400 to 1000) nm
Optical Time Domain Reflectometers (OTDRs) are also used for communication network testing. These devices combine a light source and meter, allowing analysis of reflected light to check connections, detect defects, and determine their location in optical cables.
The creation of OTDR calibration services requires equipment acquisition and service development; once we have gathered sufficient interest, we can proceed with this service.
