Unity is a linear 9620km Trans-Pacific submarine cable system connecting Chikura, Japan and Los Angeles, USA. Unity cable system was ready for service on April 1, 2010. 

Unity cable lands at Hermosa Beach in Los Angeles, with its SLTE housing at Coresite LA1 - One Wilshire carrier neutral data center, offering PoP-PoP connectivity.

Unity cable system consists of eight fiber pairs, initially designed with 96x10G DWDM system and design capacity of 7.68 Tbps.

Unity Consortium (Joint Builder) comprises Bharti Airtel (10%), Global Transit(10%), Google(20%), KDDI Corp.(10%), Pacnet (now Telstra, 40%), and SingTel (10%), which executed a Joint Building Agreement in February 2008. Unity Consortium represents a new type of consortium, Joint Build, born out of potentially competing systems, to emerge as a system within a system, offering ownership and management of individual fiber pairs for each consortium member.

Pacnet (now Telstra) owns two dedicated fiber pairs in the Unity cable system, and rebranded it as EAC Pacific.

Unity Consortium demonstrated Google's first investment in an international submarine cable system as the landing party in the United State for Unity.  Google owns one dedicated fiber pair in the Unity cable system.

Unity cable system was jointly supplied by NEC and Tyco (now SubCom). The initial construction cost of Unity cable system is approximately $300 million.

In October 2013, Pacnet (now Telstra) upgraded the EAC Pacific (Unity) with 100G DWDM technology.

In January 2023, the Unity cable system was upgraded to 7.4Tbps per FP with Infinera's ICE6 800G coherent optical solution.
