Features
  • The 1MW-12MW 1270nm-1610nm CWDM DFB Butterfly Laser Diode uses a multi-quantum well chip, satisfying the requirements for high speed optical transmission systems with a specific wavelength.
  • The built-in TEC ensures the normal operation in various environments.
  • Our high-power laser module has a low threshold current, high optical power output and large spectral width, resulting in high stability during operation.
  • It is encapsulated in a 14-pin butterfly package.
  • The butterfly packaged laser diode is applicable for modulating light sources in the communication of CATV, FTTH, GSM, and more.
