Increasing demand for fiber capacity has placed stringent performance requirements on the diode lasers used both for transmitting signals and pumping fiber amplifiers. Economic fabrication of these high-performance components in volume has in turn necessitated development of more fully automated production test equipment. At Spectracom (White Bear Lake, MN), a producer of 980-nm output diode lasers, automated test equipment is improving performance, increasing yields, and lowering cost of the final product.
