Coherent communications are the technology of choice for high-speed data transmission in telecom networks, cloud infrastructure, and inter-data center connections.

Three primary laser types power coherent systems: External Cavity Lasers (ECL), Distributed Feedback Lasers (DFB), and Distributed Bragg Reflector Lasers (DBR). DAYY Photonics offers ECLs optimized for wide tuning ranges, delivering the performance and flexibility required for modern high-speed optical networks.

Why use a DAYY Photonics source?

  1. Our light sources exhibit mode-hop-free tuning with wavelength resolution of 0.1pm and absolute wavelength accuracy within +10pm. The highly stable output and quick tuning speed of our continuous tuning models allow the units to be tuned over their entire range in less than a second.

  2. DAYY's technology provides outstanding performance with a wavelength resolution and repeatability of 1pm each, and a one-hour wavelength stability of +2pm.
