The Photonetics Osics DFB-1539.77-P13 is a Distributed Feedback (DFB) laser diode module engineered for precision optical applications requiring stable, single-frequency output. Operating at 1539.77 nm with output power greater than +13 dBm, this module integrates into the OSICS modular platform for DWDM and CWDM network testing, metrology, and sensor development. Its narrow linewidth, exceptional wavelength stability, and low relative intensity noise make it suitable for demanding telecommunications and measurement applications.
