Redondo Beach is a coastal city in Los Angeles County, California, situated in the South Bay region of the Greater Los Angeles area along the southern portion of Santa Monica Bay. Its position on the Pacific coast of the continental United States makes it a natural terminus for transpacific submarine cable systems. Two submarine cables land at Redondo Beach, connecting the United States directly to Japan across the Pacific Ocean.
Both cables landing here operate on the transpacific corridor, linking the California coast to Japan. The most prominent of these is Unity/EAC-Pacific, a published system that entered service in 2010 and spans 9,620 kilometres between the United States and Japan. The second cable, Unity, is a draft-status system also connecting Redondo Beach to Japan.
Unity/EAC-Pacific is a 9,620-kilometre submarine cable system that reached ready-for-service status in 2010. It connects Redondo Beach, California, to Japan, forming a direct transpacific link between the two countries.
Unity is a draft-status submarine cable system also connecting Redondo Beach, California, to Japan. As a draft system, full operational details remain subject to change, but its routing aligns with the transpacific corridor shared with Unity/EAC-Pacific.
Within the United States submarine cable network — which spans 113 cables across 160 landing points — Redondo Beach ranks among the upper tier, placing in the top 84% of landing points by cable count. Among California's landing points, Redondo Beach hosts fewer cables than nearby Hermosa Beach (5 cables) and Grover Beach (4 cables), though its two cables place it within the broader national footprint. Larger hubs such as Boca Raton, FL, and San Juan, PR, each host eight cables, illustrating the range of connectivity across United States landing points.
Redondo Beach functions as a focused transpacific terminus rather than a multi-corridor hub. Both of its cables connect the continental United States to Japan, meaning the landing point contributes specifically to the US–Japan segment of the Pacific submarine cable graph. The Unity/EAC-Pacific system, at 9,620 kilometres and in service since 2010, anchors this role as a published, operational transpacific route.
As one of several Southern California landing points along Santa Monica Bay and the broader Los Angeles coastline, Redondo Beach adds redundancy to the regional concentration of transpacific cable infrastructure, reinforcing the Los Angeles area's position as a key node in Pacific submarine cable connectivity.
