Description

Description
F-tone Networks’stabilized DFB lasers are high output power, narrow linewidth light sources with high side mode suppression ratios. They are available at any customer-specified wavelengths and any ITU wavelength in the S, C, L bands at  for optical sensing applications. DFB Laser are available in benchtop or OEM module. In the benchtop unit, the output power , alarms and driving current values are shown on the LCD display. Output power can be adjusted by tuning the front panel control knob. Also active emission button is used to enhance operation safety. 1MHz intensity modulation is also available. The OEM module version is an ideal building block for OEM system integrators, especially in fiber optic sensing applications. It requires only a single +5V power supply with low power consumption.
