Optical Components for Undersea Networks

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, JDSU 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

980 nm pump lasers—industry-leading 450 mW rated operating power Dual-stage isolators—industry-leading 50 dB optical isolation PIN detectors—designed for high performance, including high responsivity and low sensitivity to back-reflection and polarization Fused fiber components—advanced fused fiber technology yielding ultra low insertion loss

JDSU also provides the broadest portfolio of terrestrial dry-land fiber optic components for undersea network transmission terminal applications.

Fiber optic components for dry-land deployment
