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.
Today’s metrology capabilities of Metrosert include:
- Nominal wavelengths: 380 nm… 1100 nm, 1310 nm and 1550 nm
- Measurement range: 1 nW…4 mW (-60 dBm…6 dBm; accuracy 0.5 dBm), depending on wavelength
- Measurable parameters of the sources: optical output power over wavelengths from 250 nm to 20000 nm (accuracy 5%)
- For LED sources: spectral response over wavelengths from 380…1100 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.
