The number of channels or wavelengths that a Wavelength Division Multiplexing (WDM) Mux Demux can support depends on the specific type of WDM technology being used. There are two main categories: Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM). CWDM (Coarse Wavelength Division Multiplexing): CWDM typically supports a smaller number of channels compa...

In today's digital society, high-speed broadband connection has become an indispensable part of people's daily life and work. The broadband PON network transmits the broadband signal to the end user through the optical fiber to realize the high-speed and stable network connection. Traditional PON networks usually use a single-line single-access structure, that is, a single fiber to connect on...

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...

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...

Scheme Overview   This scheme is designed for the chain cascading transmission scenario from the central equipment room to multiple pole-mounted sites. Leveraging CWDM/DWDM wavelength division multiplexing technology, it enables multi-site and multi-service signal transmission over a single fiber or a pair of fibers through the coordinated deployment of passive multiplexer/demultiplexer devic...
