Another model takes a IO Gb/s signal, demultiplexes it electrically to generate four 2.5 Gb/s signals which are then multiplexed optically using CWDM onto one fiber. After traveling 140 km and passing through an amplifier, it is optically de-multiplexed into four 2.5 Gb/s signals and electrically multiplexed into a IO Gb/s signal. Finally, it is demultiplexed electrically. The cost savings in this model is also in the 20% to 25% range.
