Single-strand fiber WDM.
Traditional fiber optic media converters perform a useful
function but don’t really reduce the amount of cable needed
to send data on a fiber segment. They still require two strands
of glass to send transmit and receive signals for fiber media
communications. Wouldn’t it be better to combine these two
logical communication paths within one strand?
That’s exactly what single-strand fiber conversion does.
It compresses the transmit and receive wavelengths into one
single-mode fiber strand.
The conversion is done with Wave Division Multiplexing
(WDM) technology. WDM increases the information-carrying
capacity of optical fiber by transmitting two signals
simultaneously at different wavelengths on the same fiber.
The way it usually works is that one unit transmits at 1550 nm
and receives at 1310 nm. The other unit transmits at 1310 nm
and receives at 1550 nm. The two wavelengths operate
independently and don’t interfere with each other. This
bidirectional traffic flow effectively converts a single fiber
into a pair of “virtual fibers,“ each driven independently
at different wavelengths.
WDM on single-strand fiber is most often used for point-
to-point links on a long-distance network. It’s also used to
increase network capacity or relieve network congestion.
