The Photonetics OM 3646HE1540 is a tunable laser source module engineered for optical communication systems and precision spectral testing. It delivers stable, narrow-linewidth output across the C-band with mode-hop-free operation and internal wavelength referencing, eliminating external measurement dependencies. The patented TUNICS external cavity design uses Invar construction for thermal stability without active temperature control, making it ideal for DWDM applications and integrated multi-wavelength test platforms.
