Compact DFB Laser Module, Compact, Polarization Maintaining (DFB-C-PM-M)

Data Sheet

Product Overview

The Optilab DFB-C-P-M is a Distributed Feedback (DFB) Polarization Maintaining (PM) laser source module designed to work with Optilab Compact Modulator w/ Bias Control (CMB) for RFoF applications. The DFB-C-P-M can be ordered from more than 20 wavelengths in 1310 nm and 1550 nm ranges. The DFB laser’s operating temperature and output power are precisely controlled to ensure constant wavelength stability and power stability. Using its USB interface, the user can control the laser drive current and wavelength via PC interface. Contact Optilab for more information.
