WAVELENGTH DIVISION MULTIPLEXING PASSIVE OPTICAL NETWORK ARCHITECTURE WITH SOURCE-FREE OPTICAL NETWORK UNITS |
摘要 |
An optical system and method includes a source-free optical network unit coupled to an optical fiber for receiving an original carrier signal with downstream data over the optical fiber. The optical network unit includes a modulator configured to remodulate the original carrier signal with upstream data to produce an upstream data signal for transmission back down the optical fiber in a direction opposite to a direction in which that original carrier signal was received.
