One Optical Fiber Carries All Services? This Device Holds the Secret to Broadband Upgrades
Sep 19 , 2025
When you upload work files via gigabit broadband while smoothly streaming 4K IPTV programs, you may not realize that behind these "simultaneous online" high-speed experiences lies an "intelligent dispatcher of optical signals" — the PON Coexistence Wavelength Division Multiplexer (CEx-WDM). It not only makes "one optical fiber for all services" a reality but also serves as the core driver fo...

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...

What is an APD detector?
Dec 03 , 2025
The full name of an APD detector is Avalanche Photodiode detector. It is a high-sensitivity photoelectric detection device whose core function is to convert weak optical signals into measurable electrical signals. It is widely used in fields such as optical communication, laser ranging, and low-light imaging. Compared with ordinary photodiodes, its biggest advantage lies in its signal am...
