Optical Coupler

optics

i have two modems, each modem Tx signal is converted to fiber optics.

can I combine the two Tx signals (signal A and signal B) with an optical coupler?
At each time data is transmitted by only on one of the modem Tx
so that when :

A transmitting data and B doesn't transmit anything at the output of the coupler I'll receive A?
and vice versa.

Absolutely, but I suggest you do a bit of really elementary Googling before you ask this sort of question. Using "fiber optic splitter" or "fiber optic coupler will get you lots candidates. Newport, for instance has just what you need.
