As a step towards realigning its advanced fiber-optic business, 3M (St. Paul, MN) formed a new optical transport systems business unit focusing on fiber-optic solutions for bandwidth and wavelength management. The company`s Bloomfield, CT, operation, which designs and manufactures fiber-optic Bragg gratings will be consolidated into similar manufacturing facilities in Austin, TX. Administrative functions for 3M`s specialty optical-fiber business will also be centered at division headquarters offices in Austin from West Haven, CT.
