Ordering Information

NY55D Series High Power DWDM DFB laser


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