About Us
Mission
To deliver low-cost quality repairs and manufacturing in addition to thorough Fiber Characterization testing to ensure the integrity of optical networks.
Our History
Legacy Fiberoptics was formed in 2008 by the previous owner and a group of former Laser Precision, GN Nettest, and Anritsu employees with the goal of continuing service and support to thousands of loyal GN Nettest equipment customers after the Anritsu facility closed down. In 2021, Legacy Fiberoptics became a certified Service Center for Anritsu to service their RF equipment as well as optical equipment.
About Legacy Fiberoptics
In May of 2022, Gabriella Marchesani purchased Legacy Fiberoptics, Inc. from the previous owner, expanding the company’s USA-based services and continuing its excellence in providing service to the telecommunications industry. Legacy Fiberoptics maintains more than 3 million meters of characterized fiber on site. Our team takes the time to troubleshoot and repair fiber optics equipment to the component level, saving our customers time and money. Manufacturing our components in-house with OEM parts ensures quality repairs and quick turnaround times.
As the industry continues to grow, Legacy is dedicated to growing with it. We offer a range of other USA-based support in the telecommunication world like Fiber Characterization, Sales & Rentals, Trace Analysis & Training. We are committed to continuing to provide quality support to loyal GN Nettest equipment customers while growing our services to meet developing industry needs. In 2022, Legacy Fiberoptics acquired DOERS Assets and began serving all Corning Splicers and Cleavers. In August of 2024, we moved to a new facility in Utica, NY to continue to expand our service capabilities to meet growing customer needs.
As an authorized repair facility for Kingfisher, NTest, INNO Instrument, Anritsu, and a distributor for UCL Swift products, we have the experience and expertise to repair a wide variety of equipment from various manufacturers. Additionally, we have invested in new equipment to allow us the capability to service PIM and Cable Analyzers to better serve our customers.
