OPTICAL RELAY APPARATUS, OPTICAL TRANSMISSION SYSTEM, AND OPTICAL RELAY METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18277732 titled 'OPTICAL RELAY APPARATUS, OPTICAL TRANSMISSION SYSTEM, AND OPTICAL RELAY METHOD

Simplified Explanation

The optical transceiver of an optical relay apparatus includes a coherent reception front-end unit, a coherent transmission front-end unit, and an analog compensation unit.

• The coherent reception front-end unit coherently detects an input optical signal based on local oscillation light and outputs the coherently detected first analog electric signal.
• The coherent transmission front-end unit coherently modulates a second analog electric signal acquired from the first analog electric signal based on transmission light and outputs the coherently modulated output optical signal.
• The analog compensation unit performs analog signal processing on the first analog electric signal to compensate for signal quality between the input and output of the coherent front-end units, generating the second analog electric signal.

Original Abstract Submitted

An optical transceiver () of an optical relay apparatus includes: a coherent reception front-end unit () that coherently detects an input optical signal to be input, based on local oscillation light, and outputs the coherently detected first analog electric signal; a coherent transmission front-end unit () that coherently modulates a second analog electric signal acquired by turning around the first analog electric signal, based on transmission light, and outputs the coherently modulated output optical signal; and an analog compensation unit () that performs analog signal processing on the first analog electric signal in such a way as to compensate for signal quality according to a signal characteristic between an input of the coherent reception front-end unit () and an output of the coherent transmission front-end unit (), and thereby generates the second analog electric signal.
