NTT's Mist Cable RFS Summer of 2025

Image
 NTT is the lead consortium member on a new Indian subsea cable linking Mumbai and Chennai to Myanmar, Thailand, Malaysia, and Singapore. Like most cables these days Mist is a spatial division multiplexing system. It has 12 fibre pairs with aggregate transmission capacity of 240 Tbps. The DWDM backbone is 400G. Mist is part of a new wave of high capacity, high fibre count subsea cables connecting India to Europe and Southeast Asia that also includes Blue-Raman, IEX, and IAX. Information on their transmission rates is sparse, but their collective throughput is probably at least a half petabit per second and perhaps as high as 750 Tbps. NTT spent about $400 million on the project, which is part of a bigger plan to become a major data center player in India. Indian carriers still largely dominate the local data center business although that is rapidly changing as Equinix makes a concerted push. Undoubtedly, NTT management realized that the main obstacle to thriving Indian data centers...

Reached Lisbon. What's Next?

Image
Looking for new long haul providers from Portugal to Madrid and beyond? I've got them. Lisbon/Madrid/Barcelona/Marseille and Madrid/Paris. These unique routes are in the gas pipeline rights of way and often include new fibre. No Colt nor EXA in the conduit systems.   Just say no to the usual suspects. A 100G wave from LS1 to other Portuguese data centers as well as Madrid is 975 Euros on a 3 year term. You will not be in the same conduit system as Colt or EXA. In fact, most of your Layer 3 upstreams are also absent so this ideal for improving network resiliency via unique physical diversity.

Hollow Core Fibre & Its Potential In Long Haul Networks

Image
Hollow core transmits light via a central air filled tube in the fibre optic strand versus solid ultra-pure silicon. The benefit is 50% less latency which brings it within 1% of light's maximum speed. High attenuation bedeviled this technology's earliest incarnations as light would bleed and escape through the cladding. A founder of Lumenosity, the preeminent hollow core manufacturer, stopped light bleeding using a reflective layer made of silver. Photonic bandgaps are also used for the same purpose. The fibre offers several performance advantages over traditional solid core fibre: 1. Lower latency since light travels 50% faster via air. 2. Air generates less chromatic dispersion than glass. Chromatic dispersion involves the different frequencies making up a light pulse moving at different speeds. This causes a pulse meant to occupy one time slot to spread and occupy multiple time slots. The data is corrupted. 2. Less nonlinear distortions such as 4 wave mixing, stimulated Bril...

Buying Tips For The West African Coast: 2Africa & Equiano

Image
1. Senegal is really hard because several 2African consortium members decided to exclude it from their footprint. But subsea capacity demand is significant because Dakar is a natural telecom hub due to its location along the Northwest African coast. I am working on getting a good subsea 2Africa solution for African ISPs for whom Dakar is part of their plans. 2. If you planning to lease subsea capacity into South Africa or Lagos, best to wait a few months for 2Africa to go live. The combination of 2Africa and Equiano will create a temporary glut. That's the time to strike. 3. I recommend African consortium members on the Equiano and 2Africa cables over their foreign counterparts (Trump will be complaining I am discriminating against white people😄) because they have larger metro footprints. Metro waves are extremely expensive in African cities. It is likely that you can negotiate a subsea deal with an African carrier that eliminates or sharply diminishes any metro charges. I just di...

Tuesday Subsea Cable Update - APG, AAE1 Sale, And the Red Sea

Image
1. The intra-Asian APG cable has been down for an entire year. Forecast is that it will go live again end of April. 2. Bombing the Houthis is unlikely to get resolve the Red Sea impasse. Air power alone is generally ineffective. Military history says change requires boots on the ground. Indeed, most likely outcome is that the US bombings will delay any resolution. Expect futher delays for 2Africa, Blue-Raman, and SWM6 RFS dates.  3. Got 100G AAE1 wavelength capacity on non-express route for Marseille/Singapore. Available below $25K MRC per month. Big Chinese social media buyer Tiktok looking to take 10x 100Gs on same cable. So you better hurry or end up empty handed. 🙂

APG Cable Pricing: Very Low Latency Singapore/Japan Route

Image
Latency: Under 63.3 ms RTD. A point: Singapore CLS. Z point: Maruyama CLS, Japan. Service: 100G Wavelength. MRC: $15.5K. Term: 1 Year. APG has a very short subsea path from the all-important Japanese financial exchanges to their Singapore counterparts. It enjoys lower latency than ASE. But uptime has been poor so you will need redundancy on a physically diverse cable. This is challenging because Pacific Rim cable landing stations often serve a multitude of subsea networks. A typical CLS may be home to as many of 8 cables or more. I can help you in designing your trading and market data networks.

East African Subsea Cable Crisis - Capacity Shortage

Image
The East Africa capacity shortage is real and chronic. A cable serving the East Coast recently upgraded its network, but sold almost everything before the upgrade was complete. The 100G prices along the coast vary from $35K to $110K per month depending on end points. Not exacly cheap. Peace is not helping ease the crunch as the Chinese carriers are not providing leases into Kenya, but instead offering just IRUs. This eliminates most of the market as the capital required is simply too great for most players except PTTs, OTTs, and mobile carriers. The 2Africa cable is simply insufficient as Facebook kept 4 fibre pairs for itself leaving only 12 pairs for carriers' internal traffic and wholesale sales. The only other significant cables serving the Coastd are Eassy and Seacom. Neither is really high capacity by today's standards. Furthermore, 2Africa's Marseille/Mombasa segment may not be ready until 2026 given Red Sea hostilities. So regional ISPs have little choice but to hau...
