Abstract
Abstract Disclosed is a method for making the transition from a hybrid network into an all fiber network. In the preferred embodiment, the first step is to replace an existing fiber optic/coaxial cable conversion device located at a remote node with an optic distribution device. Secondly, a house optical network unit is installed in a living unit. Finally, a downstream optic fiber is installed between the optic distribution device and the house optical network unit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
63 words
A method for upgrading an hybrid fiber-coax cable network into an all fiber network, comprising the steps of: replacing a first optic fiber/coaxial cable conversion device located at a remote node with an optic distribution device; installing a house optical network unit in a living unit; and installing a downstream optic fiber between said optic distribution device and said house optical network unit.
Claim 2
Independent Claim
63 words
A method for upgrading an hybrid fiber-coax cable network into an all fiber network, comprising the steps of: replacing a first optic fiber/coaxial cable conversion device located at a remote node with an optic distribution device; installing a house optical network unit in a living unit; and installing a downstream optic fiber between said optic distribution device and said house optical network unit.
Claim 3
Dependent Claim
71 words
The method of claim 1, wherein said step of replacing a first optic fiber/coaxial cable conversion device located at a remote node with an optic distribution device further comprises the steps of: removing an upstream fiber optic cable from said first optic fiber/coaxial cable conversion device; removing a downstream coaxial cable from said first optic fiber/coaxial cable conversion device; and connecting said upstream fiber optic cable to said optic distribution device.
Claim 4
Dependent Claim
41 words
The method of claim 2, wherein said step of installing said downstream fiber optic cable further comprises: connecting said downstream fiber optic cable to said optic distribution device; and connecting said downstream fiber optic cable to said house optical network unit.
Claim 5
Dependent Claim
41 words
The method of claim 3, wherein said step of installing a second fiber optic/coaxial cable conversion device in a living unit further comprises the step of connecting said house optical network unit to an existing coaxial cable in said living unit.
Claim 6
Dependent Claim
27 words
The method of claim 1, wherein said step of installing said downstream fiber optic cable further comprises the installation of a plurality of downstream fiber optic cables.
Claim 7
Independent Claim
103 words
A method for upgrading an hybrid fiber-coax cable network into an all fiber network, comprising the steps of: placing an optic distribution device proximate to a first optic fiber/coaxial conversion device; placing a house optical network unit in a living unit; installing an optic fiber between said optic distribution device and said house optical network unit; transferring a second optic fiber from said first optic fiber/coaxial cable conversion device to said optic distribution device, said second optic fiber extending from an initial optic distribution device; and establishing a connection between said house optical network unit and a coaxial cable in said living unit.
Claim 8
Independent Claim
103 words
A method for upgrading an hybrid fiber-coax cable network into an all fiber network, comprising the steps of: placing an optic distribution device proximate to a first optic fiber/coaxial conversion device; placing a house optical network unit in a living unit; installing an optic fiber between said optic distribution device and said house optical network unit; transferring a second optic fiber from said first optic fiber/coaxial cable conversion device to said optic distribution device, said second optic fiber extending from an initial optic distribution device; and establishing a connection between said house optical network unit and a coaxial cable in said living unit.
Claim 9
Independent Claim
70 words
A method for upgrading an hybrid fiber-coax cable network into an all fiber network, comprising the steps of: replacing an optic network unit with a power-splitting (PS)/wavelength division multiplexing (WDM) device; connecting living units to said PS/WDM device with a bi-directional fiber optic cable; and installing a house optical network unit in the living units to interface between coaxial cable in the living unit and said bi-directional fiber optic cable.
Claim 10
Independent Claim
