1~20 Channel 100G DWDM Mux or Demux
Description:
Huiyuan’s Dense wavelength division multiplexer (DWDM Mux/Demux) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It provides low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path.
We make full range of DWDM products, including 50Ghz, 100Ghz and 200Ghz. Due to our rich experience of manufacturing, we make DWDM with extremely low loss and high stability and reliability. Different packages and customized package can be offered with request. Common DWDM products package include: bare single DWDM device packed in glass tube or stainless steel tube,DWDM Mux Demux modules packed in ABS box up to 16-channel or even 20-channel Multiplexing on a single fiber or DWDM modules packed in standard 19” 1U rackmount. We can also take “Skip Component” in a DWDM Mux/Demux module to reduce the total IL as an option.
