LK-NYC04D DML DFB Transmitter
- DML DFB Laser Technology
- High-Dynamic-Range
- Bandwide better than 4GHz
- CWDM Wavelength Compatibility
- Low power consumption
- Low cost
Product Description
LK-NYC04D DML Transmitter is primarily comprised of DML DFB laser, automatic optical power control circuit, voltage stabilizing conversion circuit, and monitoring indication circuit. This transmitter features DML laser wavelengths that align with the CWDM standard, specifically at 1270nm, 1290nm, 1310nm, 1330nm, 1350nm, and 1370nm.
It offers a modulation bandwidth that exceeds 4GHz and can deliver an output power surpassing 2mW. The module operates on a single positive power supply and is designed to function reliably within a voltage range from +7V to +36V. Additionally, the module is equipped with an indicator that confirms the normalcy of both the power supply and the optical power output, facilitating ease of monitoring and maintenance.
