Is DWDM and OTN the same?
Jul 24 , 2024
DWDM and OTN are two different technologies in the field of optical communication. DWDM is an optical transmission technology used to simultaneously transmit multiple wavelengths of optical signals in optical fibers, thereby expanding the transmission capacity of optical fibers, increasing network bandwidth, and supporting long-distance transmission. OTN is a network transmission tec...

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...
