Abstract
A fiber-to-coax optical network unit for converting one or more Gigabit or Ethernet Passive Optical Network (GPON or EPON) fibers to one or more coaxial cable lines to connect a subscriber's premises to a Community Access Television (CATV) system.
Claims13
An apparatus, comprising:
- a housing,
- an optical network unit positioned in the housing, the optical network unit configured to convert a fiber optical signal into an electrical signal suitable for transmission via an Ethernet cable, and
- an adaptor positioned in the housing and connected to the optical network unit, the adaptor configured to convert the the electrical signal into an Ethernet-based RF signal, the adaptor including a port configured to receive a coaxial cable connector.
A system comprising:
- a signal conversion unit positioned at a pedestal remote from a plurality of subscriber's premises, the signal conversion unit comprising an optical network unit positioned in a housing, the optical network unit configured to convert a fiber optical signal into an electrical signal suitable for transmission via an Ethernet cable, and an adaptor positioned in the housing and connected to the optical network unit, the adaptor being configured to convert the electrical signal into an Ethernet-based RF signal, the adaptor including at least one port coupled to a coaxial cable, and
- an Ethernet over Coax (EoC) converter device positioned in each subscriber's premises that is coupled to at least one coaxial cable coupled to the signal conversion unit.
A method comprising:
- positioning a signal conversion unit at a pedestal remote from a plurality of subscriber's premises, the signal conversion unit comprising an optical network unit positioned in a housing, the optical network unit configured to convert a fiber optical signal into an electrical signal suitable for transmission via an Ethernet cable, and an adaptor positioned in the housing, the adaptor configured to convert the electrical signal from the optical network unit into an Ethernet-based RF signal, the adaptor including at least one port coupled to a coaxial cable, and
- coupling an Ethernet over Coax (EoC) converter device positioned in each subscriber's premises to at least one coaxial cable that is coupled to the signal conversion unit.
