Inter-satellite optical wireless communication
Hi Everyone,
I have designed a simple inter-satellite optical wireless communication link using on-off keying. As per the data sheet of OWC component, the received power is directly proportional to the square of operating wavelength. I have compared the performance of 850 nm and 1550 nm operating wavelength using same link and system parameters. As per the data sheet, 1550 nm would have performed better. But, the results show that 850 nm performs notably better than 1550 nm. Can someone please explain the reasons for better performance of 850 nm?

Dear Amit,
please check the datasheet of the OWC component and relate results to the effect of the wavelength to the TX and RX telescope gains.

Dear Ahmad,
thank you so much for clearing my doubts..
