Coherent communications are the preferred technology for transmitting data at a high speed, primarily in telecom networks, but also in Cloud systems and connections between data centers.
Three major types of lasers are used in coherent systems: External Cavity Lasers (ECL), Distributed Feedback Lasers (DFB) and Distributed Bragg Reflector Lasers (DBR). DAYY offers an ECL that is best suited for wide tuning ranges.
Why use a DAYY Photonics source?
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.
DAYY's technology provides outstanding performance with a wavelength resolution and repeatability of 1pm each, and a one-hour wavelength stability of +2pm.
