Request InfoKVH Industries Inc.E*Core fiber from KVH Industries offers polarization-maintaining ability of >40 dBm and low sensitivity to stress and temperature. It is suitable for fiber splicing and for pigtailing to other optical components in applications where the state of light polarization must be preserved for the device to operate. An elliptically shaped core region within the fiber has a higher index than the surrounding cladding, creating the geometric birefringence necessary for light polarization. The fibers are made using silica materials and high-purity dopants.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 1/5/2024PAM4 Optical DSPsThe Perseus and Spica Gen2 from Marvell Technology, Inc. are optical PAM4 digital signal processors (DSPs) that can be used in AI, accelerated computing, and cloud services applications by optimizing...Promoted Content January 2024 IssueCO2 Laser Glass-ProcessingCO2 laser glass-processing is designed to produce high-power and sensitive photonic components and complex structures.
