DWDM (Mux-Demux) passive

  • The number of optic channels in these systems is more than 8 channels, the distance between the channels is very narrow and less than 1.6nm. Manufacturing such systems with precision, high wavelength and very narrow distance between channels requires high technology in supplying optical resources and equipment. Such systems with 16 to 40 channels and 1.6nm and 0.8 nm channel distance were made in mid 1990s.

    Building systems with more channels and consequently les distance has proceeded as at the end of 1990s, systems with 64 to 160 channels with 0.4nm and 0.2nm distance were tested.

    For the purpose of consistency and to determine the wavelength of the channels in these systems, the ITU-TG.694.1 recommendation has determined the central wavelengths per the inter-channel distance of 0.8nm, 0.8nm, 0.2nm and 0.1nm; and for the purpose of compatibility, the companies that produce the optical resources and apparatuses follow this standard.

    It should be noted that the 0.8nm distance is equivalent to 100GHz, 0.4nm equivalent to 50GHz, 0,2nm equivalent to 25GHz and 0.1nm is equivalent to 12.5GHz.

    In addition, in this recommendation, the 193.1 THZ frequency is equivalent to 1552.52nm. The range of using these systems has been divided into the two Bands C and Bands L; where Band C includes 1530~1565nm; and Band L includes 1620~1565 nm.

    Of course, the advantage of the DWEM systems is their capability in transporting very long distances on the fiber (several thousand kilometers), large number of channels (many hundred channels) as well as supporting big bit rates such as 10Gbs and 40Gbs.
