High-Reliability Applications (Submarine)

Best in class reliability, performance, and product breadth

Components for undersea cable deployment must adhere to stringent quality and reliability requirements to ensure that they operate, without failure, for a minimum lifespan of 25 years. With the broadest product portfolio and largest installed base in the industry, Lumentum is a longtime leader in supplying high-reliability, erbium-doped fiber amplifier (EDFA) components for undersea repeater modules situated every 50-100 km along the cable.

  • Wet-plant EDFA components for undersea repeaters include:
    • 980 nm pump lasers — industry-leading 450 mW rated operating power
    • Dual-stage isolators — industry-leading insertion loss and isolation
    • PIN detectors — designed for high performance, including high responsivity and low sensitivity to back-reflection and polarization

Lumentum also provides the broadest portfolio of terrestrial dry-land fiber optic components for undersea network transmission terminal applications including:

  • Modulators — the industry’s broadest range of amplitude and phase modulators for 2.5, 10, and 40G
  • Pump lasers — industry leading 980 nm and Raman pump portfolio featuring high output power and <3 FIT field failure rate
  • Tunable lasers and transponders — high-reliability tunable transmission modules for custom channel plans
  • Passive components and modules — broad range of component and module level solutions with industry leading performance and reliability
