Abstract:
1. A primary terminal of an optical transport system, the primary terminal comprising: a transponder coupled to a customer premise equipment, wherein the transponder is configured to convert a first optical signal from the customer premise equipment into a first individual long-haul optical signal, and wherein the first optical signal is in a format suitable for use by the customer premise equipment; a coarse multiplexer coupled to the transponder, wherein the coarse multiplexer is configured to multiplex the first individual long-haul optical signal into a first mux group of long-haul optical signals; and a fine multiplexer coupled to the coarse multiplexer and to an extension terminal via a metro fiber, wherein the fine multiplexer is configured to receive a second mux group of long-haul optical signals from the extension terminal, wherein the fine multiplexer is configured to multiplex the first mux group from the coarse multiplexer and the second mux group from the extension terminal into a third mux group of long-haul optical signals, and wherein the primary terminal is configured to transmit the third mux group over a long-haul network.
