DWDM multi-channel multiplexer /demultiplexer (Mux /DeMux)modules are available on ITU channel spacing of 200GHz. They demonstrate low loss, temperature insensitivity and reliable performance in any system application.Mux/DeMux modules offer low-cost wavelength management solutions that are suitable for long haul, metro, and access application
UT-King’s DWDM technology is an extension of optical networking. DWDM devices (multiplexer, or Mux for short) combine the output from several optical transmitters for transmission across a single optical fiber. At the receiving end, another DWDM device (demultiplexer, or Demux for short) separates the combined optical signals and passes each channel to an optical receiver. Only one optical fiber is used between DWDM devices (per transmission direction). Instead of requiring one optical fiber per transmitter and receiver pair, DWDM allows several optical channels to occupy a single fiber optic cable. As shown below, by adopting high-quality AAWG Gaussian technology, UT-King DWDM Mux/Demux provides low insertion loss (3.5dB typical), and high reliability. With the upgraded structure, these DWDM multiplexers and demultiplexers can offer easier installation.
