Communications
From Component Characterization to Transceiver Testing and Free Space Photonics to Quantum Developments, Calmar Lasers are enabling the Communications World
The optical fiber networks of modern telecommunication systems all utilize laser sources for high-speed, reliable transmission of digital data to support internet, video conferencing, cloud computing, etc., applications. With the increase in cloud infrastructure to support artificial intelligence (AI)-driven applications and the adoption of 5G cellular networks, data centers are migrating to 400G and up data rates to meet the demand for higher bandwidth, faster speed and lower latency performance. These new developments are putting increased demands on component test and measurement equipment.
This is the area where Calmar began its journey back in 1996 by providing the first ultrafast fiber lasers to Hewlett Packard and subsequently Agilent and Keysight. Today, its latest innovations continue to keep pace with the requirements of the higher performance infrastructure. Benchtop Mendocino ultrafast fiber lasers offering output wavelengths of 780, 850, 1310 and 1550 nm, pulse widths of < 0.3 ps and GHz synchronization signals with persistent timing jitter as low as 200 fs, are the perfect sources for next generation telecommunication component testing, high speed transceiver conformance testing and photodiode characterization. For higher frequency systems, the Eureka offers a C-band (1530-1565 nm) source with a stable optical clock up to 40 GHz, or even 640 GHz with an accessory module.
For low dispersion, low distortion, C-band channel amplification of short pulses, the Coronado series of erbium-doped fiber amplifiers (EDFA) provides a “plug and play” capability. Offered as both benchtop and module versions, these systems offer high gain (saturated power levels up to 37 dBm) and low noise (down to 5 dB) for network development.
Looking out further to future communication solutions, such as 6G cellular networks, free-space and quantum communications, Calmar lasers will continue to play an enabling role. In combination with a photoconductive emitter, the Mendocino provides a reliable source of terahertz radiation for the characterization of materials that could be deployed in 6G wireless communications. Similarly, Mendocino lasers are facilitating the development of platforms for quantum key distribution (QKD), which will be critical in ensuring secure communications in the future age of quantum computers.
Whether it is a low-jitter benchtop Mendocino, an OEM Mendocino module, a Eureka or a Coronado EDFA, Calmar offers an ultrafast fiber laser solution for your communications applications.
