DWDM - Hirundo Communication Equipment - Professional Manufacturer and Solution Provider

Dense wave division multiplexing uses the wavelength of the laser to transmit data within the fiber in parallel transmission of bitbits or string line transmission. It utilizes thin-film coating technology and the design of proprietary non-flux metal weldmicro optical packaging to achieve the upand and downlines of light within ITU wavelengths. DWDM is an important part of fiber optic network, which allows IP protocol, ATM and synchronous fiber optic network/synchronous digital sequence (SONET/SDH) protocol to carry the e-mail, video, multimedia, data and voice data are transmitted through a unified fiber layer.
