LK-NY55T High Power DWDM Transmitter
- Up to 100mw high power output
- Low Relative Intensity Noise (RIN)
- Highly integrated, module packaging
- High Reliability
- Optional ITU wavelength
Product Description
LK-NY55T Transmitter is primarily constructed with high power distributed feedback (DFB) laser, complemented by automatic optical power control circuit, automatic temperature control circuit, voltage-stabilizing conversion circuit, monitoring and indication circuit. The device is designed to span the ITU channel wavelength table for Dense Wavelength Division Multiplexing (DWDM) applications, ensuring broad-spectrum compatibility.
It can achieve a maximum output power of 100mW while maintaining low relative intensity noise, the module also exhibits excellent stability in its output wavelength, a critical parameter for reliable optical communication.. The transmitter operates on a single positive power supply and remains stable across a voltage range from +7V to +36V. Furthermore, LK-NY55T Transmitter is equipped with an indication function that signals the normal operation of both the power supply and the optical power output.
