Consider an optical communication system operating at \[\lambda \approx 800\] nm. Suppose, only 1% of the optical source frequency is the available channel bandwidth for optical communication. How many channels can be accommodated for transmitting audio signals requiring a bandwidth of 8 kHz?

• A. \[4.8\times {{10}^{8}}\]          
• B. 48
• C. \[6.2\times {{10}^{8}}\]          
• D. \[4.8\times {{10}^{5}}\]
