Telecom Test Equipment
Test operationality of high-speed coherent communications for Cloud infrastructure and data and telecom networks
Telecom and datacom solutions deliver high-speed optical connectivity within and between large-scale data centers, forming the backbone of modern digital infrastructure. DAYY Photonics’ advanced light sources enable high-speed coherent communications—the preferred technology for data transmission across cloud infrastructure, data networks, and telecommunications systems.
Our light sources span all relevant telecommunication bands, offering low coherence length and single-mode fiber output, making them ideal for use in telecommunication test equipment and other high-performance optical applications.

Our output stability maintains a high percentage of the maximum current.
Our light sources exhibit high spectral density and low unevenness to allow measurement of more attenuated devices over a wider band.
