View pageUS Patent:
20100226649, Sep 9, 2010
Filed:
Feb 22, 2010
Appl. No.:
12/709563
Inventors:
Ning Cheng - Sunnyvale CA, US
Zhishan Feng - Santa Clara CA, US

Frank Effenberger - Freehold NJ, US
Assignee:
FUTUREWEI TECHNOLOGIES, INC. - Plano TX
International Classification:
H04J 14/02
US Classification:
398 72, 398 82
Abstract:
An apparatus comprising a wavelength division multiplexing (WDM) coupler configured to couple an optical line terminal (OLT) comprising a transmitter and a receiver, wherein the WDM coupler is coupled to the transmitter via a first fiber and to the receiver via a second fiber. An apparatus comprising a WDM coupler for a passive optical network (PON) comprising a plurality of filters and a plurality of ports, wherein the WDM coupler comprises fewer filters than ports. A method comprising receiving a downstream optical signal intended for an optical network terminal (ONT) via a first fiber, and transmitting an upstream optical signal received from the ONT via a second fiber.

H03M 13/05
G06F 11/10
G06F 11/10
US Classification:
714752, 714E11032
Abstract:
A method for sending data from a transmitter to a receiver in a transmission network comprising receiving outgoing data that is eight-bits-ten-bits (8b10b) encoded at a Gigabit Ethernet (GE) line rate from a physical medium attachment (PMA) layer, 8b10b decoding the received outgoing data, 64-bits-to-66-bits (64b66b) encoding the 8b10b decoded outgoing data, forward error correction (FEC) encoding the 64b66b encoded outgoing data, and serializing and sending the 64b66b and FEC encoded outgoing data at the GE line rate to a physical medium dependent (PMD) layer.
