NY55D Series High Power DWDM DFB Laser

NY55D series laser component is characterized for use as a wavelength selected, high-power optical source in combination with an external modulator 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 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 pin-out compatible butterfly package with the optical isolator inside the package.

Precautions

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.
