GPON vs XG-PON vs XGS-PON, What's the Difference?
Sep 25 , 2025
Passive Optical Network (PON) is the core technology for fiber-optic broadband. Leveraging the advantages of "passivity" (no power supply required for the Optical Distribution Network/ODN), low cost, high reliability, and wide coverage (up to 20 km), it has become the mainstream of broadband networks. GPON, XG-PON, and XGS-PON represent three key phases in the evolution of PON technology, with cor...

Understanding Biased Detectors: Principles and Applications
Oct 24 , 2025
In the field of optoelectronic devices, biased detectors are a widely used category of specialized detection equipment. They are not devices with a single structure, but a general term for optical detection devices operating on the "reverse bias" mode. Their core lies in improving detection performance through external voltage regulation to meet the demand for high-precision optical signal capture...
