Isolated DFB Lasers, 1625

Isolated DFB Lasers 1625 We offer the PD-LD DFB series of coaxial style laser diodes with integral single stage optical isolators. The addition of these isolators ensures a minimum optical isolation of 33dB at either 1625 or 1650nm at 25°C. Optical isolation is temperature dependent and is specified as 20dB minimum over the entire operating temperature range of –40 to +85°C. These units are available in ready-to-use, fiber-pigtailed packages and are available with FC, SC and LC style optical connectors. The PD-LD InGaAsP DFB laser diodes are available in standard wavelengths centered at 1625 and 1650nm. Fiber-coupled CW (continuous-wavelength) output powers range from 0.1 – 2 mW, depending on the desired performance level. The highly stable YAG Laser welded packaging ensures a low tracking error of +/- 1.0 dB maximum over OTR -40 to +85C.
