QLM716 Directly Modulated DWDM DFB Laser Module Digital transmission up to 2.5 Gb/s 5 mW rated output power Wavelength-selectable from 1526 to 1602 nm Fiber span lengths of 100 km Pr el im in ar y Description Corning Lasertron QLM716 DFB modules are designed for use in dense wavelength division multiplexing (DWDM) systems with transmission rates up to 2.5 Gb/s and fiber span lengths of 100 km. Standard products are defined at the ITU 100 GHz channel spacings. Modules are also available with any wavelength from 1526 to 1602 nm. These modules feature the same "miniature optical bench" construction as Corning Lasertron single-channel QLM3S700, QLM5S710 and WDM QLM715 DFB laser modules for extremely stable performance over temperature and module lifetime.
