Light-to-light trans-receiver and manufacturing and using methods thereof

Abstract

The invention discloses a light-to-light receiver and manufacturing and using methods thereof. The invention discloses a light-to-light (O2O) signal path, a O2O and hybrid trans-receiver which includes the path, a network system or apparatus which includes one or more than one trans-receiver, and manufacturing and using methods thereof. The O2O signal path includes a first port and a second port, and an optical amplifier which is intended for receiving an optical signal from a host or network via the first port and transmitting an optical amplifying signal to the host and the network via the second port. In some embodiments, the O2O signal path also includes one or more optoisolators and / or clock and data recovery function. Optical signals in the O2O signal path are completely processed in light domain. The trans-receiver includes an O2O signal path and a photoelectric signal path, a transmission connector, or a second O2O signal path.

Description

Technical field [0001] The invention relates to the field of optical transceivers. More specifically, the embodiments of the present invention are applicable to optical network equipment (such as optical switches and big data storage and / or transmission devices) that can receive and / or transmit optical data signals in both directions, including such transceivers, and their manufacture and use method. Background technique [0002] The demand for network and communication bandwidth is constantly increasing. Since optical signals can transmit farther than electrical signals at the data rate required by the current network, optical networks have realized that the network can operate at higher bandwidth and speed. [0003] Although data is transmitted in the form of light through optical fibers in the optical network, the electrical domain is still used to process data in network devices, such as data center switches and servers, optical network units (ONU), optical network terminals ...

AI Technical Summary

Problems solved by technology

However, the data transmission paths inside and outside the electrical signal processing circuits operate in the electrical domain, thus increasing the complexity of the transceiver and the power consumption associated with the circuitry required in the OEO converter
