Indicator measurement precision of the SSE1MCA board

Question:
What is the precision of values measured by the SSE1MCA board in a BWS 1600G system (DWDM system)?
Answer:
1. The power monitoring precision reaches ±1 dB.
2. The OSNR under 100 GHz wavelength spacing must reach 25 dB, and the OSNR under 50 GHz wavelength spacing must reach 20 dB.
Precision requirements:
Under 100 GHz wavelength spacing, the OSNR measurement range is 10 dB to 25 dB.
a. When the input optical power is -10 dBm to -30 dBm, the OSNR test precision is ±1.5 dB.
b. When the input optical power is greater than -30 dBm and smaller than -40 dBm, the OSNR test precision is ±2.5 dB.
Under 50 GHz wavelength spacing, the OSNR measurement range is 10 dB to 20 dB.
a. When the input optical power is -10 dBm to -30 dBm, the OSNR test precision is ±1.5 dB.
b. When the input optical power is -30 dBm to -40 dBm, the OSNR test precision is ±3.0 dB.
Suggestion and conclusion:
None
