Abstract: A coherent optical communication system is disclosed comprising, a first transceiver, a second transceiver, and an optical transport medium coupling the first transceiver with the second transceiver. The first transceiver is configured to (i) receive a laser signal from a master laser source as at least one phase synchronized pair of coherent tones, and (ii) modulate data onto a first tone of the at least one phase synchronized pair of coherent tones for transport as a first data signal to the second transceiver over the optical transport medium. It is also configured to (iii) transmit a second tone of the at least one phase synchronized pair of coherent tones over the optical transport medium as an unmodulated first local oscillator signal to the second transceiver.

Abstract: An optical network communication system includes an optical hub, an optical distribution center, at least one fiber segment, and at least two end users. The optical hub includes an intelligent configuration unit configured to monitor and multiplex at least two different optical signals into a single multiplexed heterogeneous signal. The optical distribution center is configured to individually separate the at least two different optical signals from the multiplexed heterogeneous signal. The at least one fiber segment connects the optical hub and the optical distribution center, and is configured to receive the multiplexed heterogeneous signal from the optical hub and distribute the multiplexed heterogeneous signal to the optical distribution center. The at least two end users each include a downstream receiver configured to receive one of the respective separated optical signals from the optical distribution center.

Abstract: A multiple-input multiple-output (MIMO) capable system is contemplated. The communication system may include a signal processor configured to separate an input stream into multiple signal paths to facilitate simultaneous transport through a communication medium. The capability to simultaneously transmit multiples signal paths may be beneficial in order to maximize throughput and/or minimize expense.

Abstract: A method for transmitting data through a multi-media communication network includes converting transmission entities into data symbols at a first communication device, transmitting the data symbols from the first communication device to a second communication device through at least two different types of communication media using only lower PHY layers of the at least two different types of communication media, and converting the data symbols into transmission entities at the second communication device. A network implementing a universal data link includes a first communication device configured to convert transmission entities into data symbols, a second communication device configured to convert the data symbols into transmission entities, at least a first communication medium and a second communication medium communicatively coupled between the first communication device and the second communication device, and a first physical-layer translator configured to translate data symbols without converting the data symbols into transmission entities. In order to reduce processing time and end-to-end latency, the physical-layer translator only performs demodulation and modulation operations, optionally also equalization.
