With the advantages of large bandwidth, strong parallel processing ability and low transmission loss, microwave photonic technology has the potential to break the technical bottleneck of traditional microwave systems and improve the performance of military electronic information equipment such as radar, electronic warfare, communications, measurement and control. The microwave photonic system constructed by discrete devices has the problems of large volume, heavy weight and poor stability, which seriously restrict the application of microwave photonic technology in spaceborne and airborne platforms. Therefore, the integrated microwave photonic technology is becoming an important support to break the application of microwave photons in military electronic information systems and give full play to the advantages of microwave photonic technology.

Fiber optic connectors, that is, fiber optic connectors for accessing optical modules, also have many kinds, and they cannot be interused with each other. People who do not often touch optical fibers may mistakenly think that the optical fiber connectors of GBIC and SFP modules are the same, but they are not. The SFP module is connected to the LC fiber optic connector, while the GBIC is connected to the SC fiber optic connector.

A semiconductor optical amplifier is an optical amplifier based on a semiconductor gain medium. It is essentially like a fiber-coupled semiconductor laser tube, the end mirror has been replaced by an AR coating; a tilted waveguide can be used to further reduce the end reflectivity. The signal light is typically transmitted through a semiconductor single-mode waveguide with lateral dimensions of 1-2 μm and a length of about 0.5-2mm. The waveguide mode has significant overlap with the active (amplified) region, which is pumped by the current. The injection current generates a certain carrier density in the conduction band, allowing an optical transition from the conduction band to the valence band. The gain maximum occurs at photon energies slightly above the bandgap energy.

12/13/2023, Optical Fiber Online News, November 20-December 1, 2023, the third plenary session of the 2022-2024 research period of Study Group 15 (SG15) of the International Telecommunication Union Standardization Sector (ITU-T) was held in Geneva, Switzerland. A total of 230 representatives from 17 national members, 38 sector members and 13 sector associate members attended the meeting. A total of nearly 70 experts from 12 member units of the Chinese delegation attended the meeting on the spot and submitted 148 technical proposals, which promoted the deliberation, approval and adoption of 25 standard suggestions and 4 technical supplement documents with Chinese experts as editors. Among the 45 new proposals, china's 32 experts served as editors of 3 new standard recommendations, 18 existing standard recommendations and 6 technical additions.
