Abstract
A method and system is disclosed to optically transport data at a data rate of about 5 Gbps without chromatic dispersion compensation. After receiving a first data stream at a data rate of about 2.5 Gbps and a second data stream at a data rate of about 2.5 Gbps, the first and second data streams are combined into a third data stream at a data rate of about 5 Gbps by interleaving the first data stream and the second data stream, wherein the third data stream is modulated for optically transporting the same from a transmission end.
Claims21
A method for optically transporting data without chromatic dispersion compensation, the method comprising:
- receiving a first data stream at a data rate of about 2.5 Gbps;
- receiving a second data stream at a data rate of about 2.5 Gbps;
- framing the first data stream into a first framed data stream;
- framing the second data stream into a second framed data stream;
- and
- combining the first and second framed data streams into a third data stream at a data rate of about 5 Gbps by interleaving the first framed data stream and the second framed data stream,
- wherein the combining is subsequent to the framing steps,
- wherein the third data stream is modulated for optically transporting the same from a transmission end.
A method for optically transporting data without chromatic dispersion compensation, the method comprising:
- receiving a plurality of incoming data streams at an original data rate lower than about 2.5 Gbps;
- framing the plurality of data streams into a plurality of framed data stream;
- and
- combining the plurality of framed data streams into an outgoing data stream at a data rate of about 5 Gbps by interleaving the framed data streams,
- wherein the combining is subsequent to the framing,
- wherein the outgoing data stream uses a non-SONET/SDH frame and is modulated for optically transporting the same over a long distance from a transmission end.
A system for optically transporting data using a 5 Gbps transport rate without chromatic dispersion compensation, the system comprising:
- a first framer for receiving and framing a first data stream;
- a first converter for transporting the framed first data stream at an original data rate of about 2.5 Gbps;
- a second framer for receiving and framing a second data stream;
- a second converter for transporting the framed second data stream at an original data rate of about 2.5 Gbps;
- and
- a 5 Gbps transceiver for combining the first and second framed data streams into a third data stream at a data rate of about 5 Gbps by interleaving the first framed data stream and the second framed data stream,
- an optical transmitter for modulating the third data stream for optically transporting the same over a long distance from a transmission end to a receiving end
- wherein the first and second data streams are framed before the first and second framed data streams are combined into the third data stream.
