Price and availability check
The invisible infrastructure of global connectivity
The Jupiter submarine cable is an advanced trans-Pacific cable system connecting North America with Japan and the Philippines. A joint project between Amazon, Facebook, PCCW Global, SoftBank and Philippine Long Distance Telephone Company, Jupiter represents the growing importance of privately funded hyperscaler cables in the trans-Pacific region. Jupiter’s unique connectivity to the Philippines sets it apart from other trans-Pacific cable systems and provides direct access to one of the fastest growing digital markets in Southeast Asia. Submarine cables like Jupiter form the invisible foundation of global data traffic, with over 99% of international data flowing through them rather than satellites or the cloud.
Route & connection
Jupiter connects Harbor Pointe (Oregon, USA) with several landing points in Japan and Daet in the Philippines. This route makes Jupiter one of the few trans-Pacific cable systems to connect the Philippines directly with North America and Japan. With a total length of around 14,000 kilometers, Jupiter bridges the Pacific on one of the most strategically important data routes between North America and Southeast Asia.

What is the Jupiter cable?
Jupiter is a trans-Pacific submarine cable connecting Maruyama and Shima in Japan via a main trunk to Hermosa Beach, California, with additional branches to Pacific City, Oregon, and Daet in the Philippines. The cable spans around 14,000 kilometers; the main trunk entered service in May 2021, with the Philippines branch following in July 2022. Across five fiber pairs in the main trunk, Jupiter reaches a design capacity of more than 60 Tbit/s. It was built by TE SubCom and is funded and operated by a consortium comprising Amazon, Meta (formerly Facebook), NTT, PCCW Global, PLDT and SoftBank. Its direct connectivity to the Philippines sets Jupiter apart from most other trans-Pacific cables.

Jupiter submarine cable

Technology & capacity
Jupiter uses state-of-the-art fiber optic technology and offers a capacity of up to 60 Tbit/s, which meets the growing requirements of international companies with transpacific bandwidth needs. Essentially, these are the technological features:
- Open Cable Design: Jupiter is designed as an open cable system that offers the consortium partners maximum flexibility when using their own transmission technology.
- Multiple landing points: Connecting multiple Japanese landing points as well as the Philippines creates flexibility and real route options for users in the region.
- The latest generation of fiber optic technology for minimal signal loss and stable transmission quality across the entire transpacific route.
Provider Overview
SAVECALL as access to Jupiter
Jupiter’s direct connection to the Philippines makes it a particularly strategically valuable cable system for companies with a presence in Southeast Asia. The Philippines is one of the most dynamically growing digital markets in the region and is also one of the world’s leading countries in the field of business process outsourcing. A direct, low-latency connection via Jupiter is a decisive competitive advantage for companies in this environment. Access to capacity on Jupiter requires direct wholesale partnerships and deep market knowledge of the trans-Pacific cable landscape. This is exactly where SAVECALL comes in. We have direct market access, analyze your connectivity strategy and source capacity on Jupiter specifically for your requirements.
The result for our customers:
- Direct capacity access to Jupiter without reseller chains
- Transparent price benchmarking and market data
- Direct connection to the Philippines and Japan via a transpacific route
- Negotiation of IRU structures and leased capacity models
- Clear SLAs and ongoing capacity management

Jupiter compared
On the trans-Pacific route, Jupiter competes with other modern cable systems, each offering different landing points, capacities and ownership models. For procurement decisions, what matters most is whether direct Philippines connectivity is required, or whether an established Japan-US route or maximum failover reliability takes priority. The comparison below positions Jupiter against FASTER and Tata TGN-Pacific.
| Criterion | Jupiter | FASTER | Tata TGN-Pacific |
|---|---|---|---|
| Route | Japan (Maruyama, Shima), US (Hermosa Beach, Pacific City), Philippines (Daet) | US (Bandon, Oregon), Japan (Chikura, Shima), Taiwan (Tanshui) | US (Nedonna Beach OR, Hermosa Beach CA), Japan (Emi, Toyohashi), Guam (Piti) |
| Design capacity | more than 60 Tbit/s | 60 Tbit/s | up to 77 Tbit/s (after 100G upgrade) |
| In service since | 2021 (Philippines branch 2022) | 2016 | 2002, upgraded to 100G since |
| Fiber pairs | 5 in the main trunk | 6 | 8 per route (dual-ring structure) |
| Ownership model | Consortium (Amazon, Meta, NTT, PCCW Global, PLDT, SoftBank) | Consortium (Google, KDDI, SingTel and others) | Tata Communications, sole owner |
| Strength | only one of the three systems with direct Philippines connectivity | direct connectivity to two Japanese landing points and Taiwan | self-healing ring topology with automatic failover on cable break |
Vendor-neutral assessment: SAVECALL does not rank Jupiter, FASTER and Tata TGN-Pacific against each other, but views them as complementary building blocks for resilient trans-Pacific connectivity. Which cable or combination makes sense for a business depends on the required landing points in Japan, Taiwan or the Philippines and existing carrier relationships. As a carrier-neutral consultancy, we source capacity across all relevant systems and recommend purely based on actual requirements.

Frequently asked questions about the Jupiter cable
Jupiter connects the Japanese landing points Maruyama and Shima via a main trunk to Hermosa Beach, California, with branches to Pacific City, Oregon, and Daet in the Philippines. For companies with sites in Japan, the US or the Philippines, Jupiter offers one of the few trans-Pacific routes with direct Philippines connectivity.
Jupiter reaches a design capacity of more than 60 Tbit/s, spread across five fiber pairs in the main trunk plus two additional fiber pairs each in the Oregon and Philippines branches. This makes Jupiter one of the higher-capacity trans-Pacific systems of its generation.
Jupiter’s main trunk entered service in May 2021, with the Philippines branch following in July 2022. The cable was built by TE SubCom and is operated by a consortium comprising Amazon, Meta, NTT, PCCW Global, PLDT and SoftBank. This broad participation of major technology and telecommunications companies ensures a solid user base.
This mainly depends on the landing points you need. Jupiter is a good fit if direct Philippines connectivity is required, FASTER offers an established route to Japan and Taiwan, and Tata TGN-Pacific provides maximum failover reliability through its self-healing dual-ring structure. Combining two systems is often the better choice to ensure genuine route diversity. SAVECALL advises on the right combination on a vendor-neutral basis.
Genuine redundancy only exists when the chosen cables use different landing points and physically separate routes, for example combining Jupiter for Philippines connectivity with another system like FASTER or Tata TGN-Pacific for Japan. The landing stations themselves should also be redundantly connected, so that a local outage does not jeopardize the entire connection. SAVECALL plans these concepts independently of any single cable operator, with a focus on actual failover reliability.
Access to capacity on Jupiter runs through direct wholesale partnerships with the consortium partners, as well as IRU or leased capacity agreements. SAVECALL negotiates these structures directly with the relevant carriers, without detours via reseller chains. Book a free consultation to discuss the right capacity solution for your business.
