Infrared communication in space over 15 foot distance

Infrared communication in space over 15 foot distance

Infrared communication in space over 15 foot distance

(OP)
I am designing a space based antenna array and would like to talk from one part of the antenna to the other part using simple infrared transmitters and receivers, similar to your remote control on the television, i.e. something cheap for our high quantity. The receivers will often be hit with direct sunlight. Tranceiver units would be best so there is two way communication. Is there any way to use IR or other filtered light to send simple digital codes for a distant of 10 to 15 feet in space (MEO orbit)? Our present discussion is to use fiber optic cables to distribute commands, but it would be much simpler, cheaper and better for testability if light was used.
Any hardware suggestions?

You have posted this in the wrong forum.  This forum deals with thermal infrared imagging, not IR communications.

Direct sunlight in space is very wideband and strong signal. I would use HF -- first guess << 1 MHz with a  narrow band subcarrier.
