  • Application

    • CWDM-PON system
    • WDM-PON system
    • DWDM-PON system
  • Features

    • Expandable to up to 36 channels
    • Sending/receiving a quantity of data at high speed
  • Description

    • CWDM wavelength used for (WCDMA(CCC), WCDMA(5/6FA), WiBro, LTE) by service will run out soon because of explosively increasing wireless traffic. Thus, the necessity to use new C-Band DWDM wavelength has been coming to the fore. CWDM products of Fiberpia can be expanded to 36 channels, twice as more than existing 18 channels. The filter in CWDM splits the wavelength with the error range of +/-2nm from the center wavelength. Thus, it can send or receive a large quantity of data at high speed by splitting the wavelength in 1270nm or 1610nm into 36 channels. The existing CWDM environment can be used for it without any change.
