Abstract

Optical signals generated from customer premise equipment (CPE) at the edges of the metro domain networks are facilitated. The CPEs connect to extension terminals that transform the optical signal originating at the CPE into a format for long haul transmission. The optical signal then propagates to a primary terminal where the signal is multiplexed with other optical signals from other extension terminals. The multiplexed signals are then transmitted to a second primary terminal. The signal is then demultiplexed from other optical signals and transmitted to the proper extension terminal. At the extension terminal, the demultiplexed optical signal is transformed from its LH format back into a format suitable for inter-connection to a CPE. The signal undergoes optical-to-electrical conversion only at the extension terminals or end points, which can be located at lessee's facility. The only equipment located in lessor's facility is the primary terminal containing line amplifiers and add/drop nodes.
