Lumentum’s integrable tunable laser assemblies (ITLAs) deliver ultra-stable, tunable carriers across the C, L, and C+L bands for DWDM networks. With sub-MHz linewidth and integrated wavelength and power control, they maintain precise phase and frequency stability over temperature and distance—critical for higher-order modulation formats.
The portfolio includes high-power variants for amplified and subsea spans, industrial-temperature models for edge and access environments, and ZR-optimized designs for coherent pluggable transceivers. Built on Lumentum’s proven indium phosphide (InP) platform, these ITLAs underpin metro, long-haul, and data center interconnect (DCI) links and serve as local oscillators inside coherent modules.
