A new series of collimators are designed to focus/collimate light exiting a fiber to a desired beam diameter or spot size. Available in either short- or long-focus models with FC or SMA connectors and molded aspheric glass lenses with an AR coating. They are available in one of three wavelength ranges: visible (488 to 633 nm), visible-NIR (650 to 870 nm), and IR (1064 to 1550 nm). Housed in 303 stainless steel, the diffraction-limited lenses allow users to reach spot size down to a few microns.

A new 980-nm pump laser product line for EDFAs utilizes a proprietary facet design and coating process for reliable, kink-free powers of >700 mW. They are designed to increase the threshold at which catastrophic optical damage (COD) at the laser facet can occur. Values of 20 MW/cm2 are achieved, compared to typical industry values of 12 MW/cm2. Three grades of devices are available: 150+ mW for uncooled, low-cost, metro pump applications; 300+ mW for mid- to low-power pump modules; and 500+ mW for high-power applications.
