How to get the Different Frequency [Wavelength] Values for different Fix Channel Spacing in Optical?
In this Video we will learn how to get Different Frequency [Wavelength] Values for different Fix Channel Spacing [12.5 GHz , 25 GHz , 50 GHz and 100 GHz].
Comparison of all channel-spacing Frequency value.
The Formula for Calculating the Frequencies Values:-
Standard Formula:- 193.1+(n × Channel Spacing {in THz})
For channel spacing of 12.5 GHz
The allowed channel frequencies (in THz) are defined by: 193.1 + n × 0.0125 where n is a positive or negative integer including 0.
For channel spacing of 25 GHz
The allowed channel frequencies (in THz) are defined by: 193.1 + n × 0.025 where n is a positive or negative integer including 0.
For channel spacing of 50 GHz
The allowed channel frequencies (in THz) are defined by: 193.1 + n × 0.05 where n is a positive or negative integer including 0 .
For channel spacing of 100 GHz
The allowed channel frequencies (in THz) are defined by: 193.1 + n × 0.1 where n is a positive or negative integer including 0 .
