Core and principle of test environment construction:
1. Check whether the optical power exists
Generally use optical power to test whether there is optical power; And the optical power of some ophthalmograms is -2dbm, -3dbm, etc.
2. Whether the clock is accurate
The clock is the reference information that displays the eye map. Loss, loss state: there is a signal in the eye map, but it is confused and fuzzy, and it cannot be formed.
3. Setting of eye map
Transmission rate selection; Filter selection; Display of extinction ratio and other information
4: Principles
The light is controlled within a certain range, input to the eye map instrument, and the clock of the light is input to the eye map instrument.
Test environment simulation and practice:
The above is the introduction article about the construction of test environment brought by Shenzhen HDV Phoeletron Technology LTD., and our company is a specialized manufacturer of optical network, the products involved are ONU series ( OLT ONU/AC ONU/CATV ONU/GPON ONU/XPON ONU). Optical module series (optical fiber module/Ethernet optical fiber module /SFP optical module), OLT series ( OLT equipment / OLT switch/optical cat OLT), etc., There are various specifications of communication products for the needs of different scenarios for network support, welcome to consult.
