Description
1×2 DWDM
1×2 Dense Wavelength Division Mulitplexer (DWDM) is a fiber component built with thin-film filter technology, it allows one specific DWDM wavelength to pass and reflect the other, it’s widely used in WDM access network and fiber amplifier systems, the high isolation type is available upon request.
