Task for today
Today is the 5th year I came to Sweden, Stockholm. I hope I can become better and better in myself and my everything. Some tasks for today.
- Understand Optical power, average and peak power. And corresponding calculation.
- Verify the code for RRU2217, check the code for set rx and set tx as well.
- Meeting at 12:00 with Carl for DSX-5000.
Go to gym for training.
Optical Power
Total power, average power, peak power, what is the meaning for them? How to calculate and the relationship between them
Question from ResearchGate How to count total power from OSA
1. Peak power and Average power
In general speaking, Average power is the laser output power from the light souce. The value depend on the souce, e.x, LED souce or other different source. See introduction
2. Optical spectral power
Optical spectrum analysis is the measurement of optical power as a function of wavelength. See description here
3. RJ45 Standards
ISO/IEC 11801:1995
- define the channel and permanent link
- Channel excludes the connections at application-specific equipment
- Permanent link is the transmission path includes connections at the ends of linstalled cabling.
- No define for patch cord cable
ANSI/TIA/EIA-568:A
- clause 6.6, define cord cable,
IL,RL - clause 6.8, define connectors,
IL,RL,NEXT,FEXT - clause 6.9, define cable assembles (patch cord, work area cables),
RL,NEXT
