Product Introduction

This is a CWDM 1270-1650nm DFB Laser Source with Built-in Drive Circuits adopting a DFB semiconductor laser chip, with output power over 10mW, SM/PM fiber, and excellent power & spectral stability. It supports benchtop and modular configurations with a communication interface or a monitoring software for systems integration. Suitable for nonlinear optics research, fiber laser pumping, and optical testing systems. Avoid frequent plugging/ unplugging of fiber connectors to prevent dust accumulation and end-face damage.

Operation Steps

Step1.Unpacking: Before assembly, check whether all accessories are complete, including laser source module, USB data cable, power adapter, test report, etc.

Step2.Power supply: Connected to a DC switching power supply or a regulated power supply that meets their power supply requirements. Use only the original matched power adapter (DC5V or DC12V). Improper power adapters may damage the light source. (Power adapter supplied according to local voltage standards.)

Step3.Connecting output fiber: Open the dust cap at the fiber connector or flange, check the fiber end face, and connect the fiber or splice the fiber to the device or power meter to be tested after confirming that there is no pollution and damage.

Setp4.Connect to the host computer: Use the USB-RS485 DB9 Data Cable to connect the DFB Laser Source and the computer; the computer must first install a dedicated serial port driver to identify the USB-RS485 serial port data cable, otherwise the host computer software and the light source module cannot be correctly connected and communicated. Please ask Box Optronics for the driver.

Step5.Control software: Box Optronics provides the serial command or PC software to control the LD current and LD temperature of the DFB Laser Source. Choose the correct port, set the current and temperature, then click the open button. (To prevent damage, ramp up the drive current slowly at initial operation. Do not apply full current immediately.)

Step6.After use, click the close button, turn off the power supply, and disconnect the fiber connection.

Operation Notes and Maintenance

● Avoid frequent plugging/ unplugging of fiber connectors to prevent dust accumulation and end-face damage.

● Clean fiber connectors with a lint-free wipe and inspect with a fiber end-face detector before connection. Always connect/disconnect fibers without power to avoid end-face burning. Cap unused connectors with dust caps.

● Store the equipment in a dry, moisture-free environment.

● When using the laser source module for a long time, remember to consider the heat dissipation and ventilation of the module and place the module on the heat sink.
