Embodiment Construction

[0020] The following examples relate to providing a Passive Ethernet Optical Network over Coax (EPOC) network comprising communications between optical network equipment of the EPON and coaxial cable network equipment of the coaxial cable network. The term "coaxial" herein refers to a coaxial cable. EPOC enables established end users connected to coaxial cable networks to connect to EPON and take advantage of the high speed communications associated with EPON. EPON frames of data are transmitted between EPON and the coaxial cable network.

[0021] figure 1 An EPOC network 10 is shown. EPOC network 10 includes service provider's optical cable module (OLM) 12, optical network module 1-N (ONM)14 and Coaxial Network Module 1-M (CNM) 16. OLM 12 may be located in optical cable termination 17 and connected to ONM 14 via PON 18 and may be located at the service provider's central office. PON 18 may be an EPON and includes one or more passive optical splitters (a single passive ...

Abstract

A conversion module including a physical layer module and a control module and a first network module of an end-user device are disclosed. The physical layer module receives first data from a service provider via an optical network. The control module, via the coaxial cable network: transmits first data from the conversion module to the first network module via the subcarriers according to the first bitloading profile; requests from the first network module or the second network module to indicate the A report of channel conditions; receiving the report based on the request; updating the second bitloading profile based on the report; transmitting the updated second bitloading profile or the first bitloading profile and the first bitloading profile to the first network module or the second network module the difference between the updated second bitloading profile; The network module or the second network module transmits the second data.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 900,532, filed November 6, 2013. The entire disclosure of the above-mentioned application is incorporated herein by reference. technical field [0003] This disclosure relates to Ethernet Passive Optical Networks (EPON). Background technique [0004] A service provider may provide Internet access and telephony services to end-user devices such as televisions, computers, and telephones via telephone cables (eg, twisted pair cables) of a telephone network. Internet access and telephone service may be provided over the telephone network via a Digital Subscriber Line (DSL) connection. Alternatively, Internet access and telephone service may be provided via a coaxial cable network. A coaxial cable network connects a service provider's central office to end-user equipment via coaxial cables. The telephone network may include a power splitter and tr...
