NY55D Series High Power DWDM DFB Fiber Coupled Laser Diode

  • NY55D series fiber-coupled laser diode is characterized for use as a wavelength selected source(CW optical source) in combination with the external modulators in CATV and DWDM networks, especially for super trunking and distribution. Selected wavelengths comply with ITU Grid recommendations, both in range and in channel definition.
  • NY55D series fiber-coupled laser is equipped with polarization maintaining (PM) fiber and dc-coupled with a built-in TEC, thermistor, and monitor photodiode. The device is mounted in a 14-pin, OC-48 pinout compatible butterfly package with the optical isolator inside the package.

Precautions

  • The fiber bending radius no less than 20 mm for avoiding fiber damaged.
  • Be sure the fiber coupling facet is clean before connecting it to Opto-circuit.
  • Suitable ESD protection is required in storage, transportation and use.
