Product details for Dense Wavelength Division Multiplexer

DWDM Mux/Demux(Dense Wavelength devision multiplexer) and Optical Add Drop Multiplexer (OADM) units to suit all kinds applications and network solutions, such as: Gigabit & 10G Ethernet, SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV.

Dense Wavelength Division Multiplexer (DWDM)series are designed and manufactured to Telcordial standard and ITU standard. The devices use environmentally stable Thin Film Filters and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation and excellent environmental stability. They can be used individualy to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in DWDM systems.

Dense wavelength division multiplexing (DWDM) is a technology that puts data from different sources together on an optical fiber, with each signal carried at the same time on its own separate light wavelength. Using DWDM, up to 80 (and theoretically more) separate wavelengths or channels of data can be multiplexed into a lightstream transmitted on a single optical fiber. Each channel carries a time division multiplexed (TDM) signal. In a system with each channel carrying 2.5 Gbps (billion bits per second), up to 200 billion bits can be delivered a second by the optical fiber. DWDM is also sometimes called wave division multiplexing (WDM).

DWDM component is based on proven thin-film technology, it can be used in multi-channel DWDM module and other optical system. And DWDM module has been widely used in CATV system, FTTH system etc.
