FIBER TO THE CURB AND FIBER TO THE NEIGHBORHOOD POWER ARCHITECTURE
First Claim
1. A system for powering a fiber optic communication network which transmits communication data between a telephone company central office and a remote user device, the system comprising:
- a digital subscriber line access multiplexer for converting the communication data from a digital optical state to a digital electrical state;
a fiber optic communication medium configured to transfer the communication data between the telephone central office and the digital subscriber line access multiplexer;
a power source configured to supply an electrical supply voltage to power the digital subscriber line access multiplexer, the power source having an AC power feed for providing power to the digital subscriber line access multiplexer and a DC power feed for providing power to the digital subscriber line access multiplexer when the AC power feed is not supplying power to the digital subscriber line access multiplexer; and
an electrical conducting medium configured to conduct the electrical supply voltage and the communication data from the digital subscriber line access multiplexer to a network interface device in electrical communication with the remote user device.

Abstract
A system and method of powering a fiber optic communication network are provided which transmits communication data between a telephone company central office and remote user device. The system includes a power source configured to provide an electrical supply voltage to a digital subscriber line access multiplexer. The power source having an AC power feed for providing power to the digital subscriber line access multiplexer and a DC power feed for providing power to the digital subscriber line access multiplexer when the AC power feed is not supplying power. Further, an electrical conducting medium configured to conduct the electrical supply voltage and the communication data from the digital subscriber line access multiplexer to the remote user device is provided. Therefore, the present invention provides a system and method for reliably powering a fiber optic communication network with AC power under normal operating conditions and DC backup power when the AC power is interrupted, thus providing lifeline telephony service while, reducing maintenance costs by having a limited number of centralized remote power sites.
