- 詳細技術說明
- The novel technology provides an effective all-optical solution for upconverting baseband data to the microwave band, while performing AM-to-FM transformation simultaneously. This simplifies the design of the central office by combining the functionality of signal conversion and an optical source into a single device, eliminating the need for separate and expensive microwave components and high-speed optical modulation electronics. Furthermore, the optical conversion rates of this technology can exceed the bandwidth constraints of conventional high-speed electronic conversion equipment.

Background
Wireless communication technology has increased demand for data transmission between wireless devices and base stations. Base stations communicate via radio-over-fiber with a central office, which manages data flow conversion between the base stations and the conventional optical communication network. The central office requires expensive and complex electronic microwave conversion equipment to allow communication between the base stations and the conventional optical communication network. The central office conversion is inefficient and bandwidth limited.
