Description Alliance Fiber Optic Products (AFOP) unites with light. Communications equipment manufacturers incorporate AFOP's fiber-optic components into products used to build networks that connect cities, regions within cities, and telecommunications service providers with their individual customers. Its optical path integration and optical fiber amplifier components, which include attenuators, couplers, depolarizers, multiplexers, and splitters, account for most of sales. The company sells directly to telecom equipment makers, primarily in North America, where it gets about half of sales. AFOP has more than 200 customers.
