Engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA says that its manufacturing operations have reached two shipment milestones: 3 million pump laser modules and half a million erbium-doped fiber amplifiers (EDFAs).
Advances in DWDM technology over the last two decades have enabled rapid scaling of optical communications infrastructure by several orders of magnitude, notes II-VI. The firm’s pump lasers and EDFAs boost the power of optical signals at regular intervals along fiber-optic transmission lines.
“II-VI’s high-performance gallium arsenide semiconductor lasers and differentiated EDFA design and manufacturing capabilities enable as much as 50% of all global internet traffic running through the optical transport network,” reckons Sunny Sun, president of the firm’s Photonics Segment. “Our pump lasers have stood the test of time and demonstrated decades of reliable operation, even on the ocean floor,” he adds. “By leveraging our own pump lasers, thermoelectric coolers, micro-optics and leading-edge amplifier control electronics, our EDFAs reflect our expertise in vertical integration.”
II-VI says that its GaAs lasers and EDFAs trace their intellectual property, technology and reliability heritage to industry pioneers. The lasers are designed and manufactured in Zurich, Switzerland, leveraging a legacy that spans more than 20 years. The laser chips are assembled on ceramic sub-mounts in Calamba, Philippines, and packaged on automated assembly lines in Shenzhen, China.
