Abstract
Alternative methods and apparatus for introducing narrowcast transmission signals into a fiber optic broadcast network utilizing rare-earth-doped fiber amplifier technology are disclosed. The methods and apparatus include utilizing an existing 1480 nm pumping laser in an erbium-doped fiber amplifier to transmit a narrowcast signal into a 1550 nm broadcast transport fiber. The 1480 nm narrowcast signal is split off from the amplified 1550 nm broadcast signal(s) in order to bypass a 1550 nm optical isolator located at the output of the amplifier and then recombined with the broadcast signal(s) after the isolator.
