## @PhotonCap (Photon Capital) · 09-20 19:45 · ♥36 ↻8 💬4 Lumentum's OCS (optical circuit switch) revenue crossed $100 million a quarter one year after it recognized first revenue last August. This switch is a million times slower than an electrical one.

The body is free. The 300-port arithmetic and what's happening outside Google are the subscriber bonus.

What the free section covers:

- What an OCS actually does in a data center, and how it removes the electrical conversion - Why Google has used this slow mirror for a decade A first read on whether a millisecond mirror is still enough - A switch a million times slower than everything around it is sitting in the middle of the most expensive computers on earth.

## @Normal_2610 (Normal Guy) · 09-20 18:28 · ♥37 ↻3 💬0 Welspun has associate company called EPIC in Saudi Arabia that makes large steel pipes

EPIC just won ₹2,000 crore order from Saudi Aramco, which is Saudi Arabia giant oil company. Aramco is building 4,000 km of new gas pipelines to shift power plants from oil to gas. EPIC makes 500,000 tonnes of pipes every year and its revenue grew 25% last year reaching SAR 2,300 million.

This contract runs for six months. Revenue will show up in EPIC numbers from Q4 FY27. Welspun owns 22% of EPIC

Saudi Arabia wants 75% of Aramco spending going to companies manufacturing inside Saudi Arabia by 2030. EPIC manufactures pipes right in Dammam, giving it scoring advantage over imported pipes.

Welspun is also building another pipe factory in Dammam with 350,000 tonnes per year capacity for different pipe type called LSAW. So Welspun will soon have two separate pipe factories in Saudi Arabia making two different products.

Aramco spends around ₹50 billion every year on projects. Companies manufacturing locally get first preference on every new pipeline contract

Welspun Corp just posted ₹1,047 crore profit in Q1 FY27, triple compared to same quarter last year. Big part of that jump came from selling 4.5% of its EPIC shares for ₹548 crore gain.

Even removing that one-time gain, regular profit grew 42% to ₹499 crore. Welspun total pending orders sit at ₹25,750 crore globally. Saudi Arabia has over $1 trillion in active projects.

Jafurah gas field alone needs over $100 billion. EPIC sits right in middle of this spending and Welspun takes home 22% share of EPIC's profits

Did wrote in past middle East + Data center US + India later 2028 onward > 引用 @Normal_2610: Welspun Corp earns roughly 3X more profit per tonne of pipe sold in United States compared to India.

That gap is not about quality of pipe, which is the same steel welded in the same way. Gap comes from trade protection. US imposes anti-dumping duties on imported pipes, so a manufacturer who already runs a plant inside America faces far less competition and can charge more.

Welspun now plans to add 200,000 to 250,000 tonnes of new capacity at its Arkansas plant this year, a 70% jump. Every tonne produced there earns at a level Indian operations cannot match.

Demand for large steel pipes in America is being driven by something that has nothing to do with oil prices. Data centres need gas powered electricity, and gas needs pipelines.

US developers plan to add about 45 billion cubic feet per day of new pipeline capacity in 2026 and 2027, biggest buildout since 2008. Welspun US spiral pipe mill is already fully booked through FY28.

Once the new LSAW line comes online, it will be the only American plant that can make pipes from 6 inches to 56 inches wide, covering every specification from small city gas lines to massive LNG export corridors.

Q1 FY27 reported profit tripled to 1,046 crore, but about 548 crore of that came from selling shares of its Saudi associate East Pipes on Tadawul stock exchange.

Strip that out and operating profit still grew 35%, which is strong but not as dramatic. Management reiterating 2,800 crore EBITDA guidance for full year without raising it, even after a strong first quarter, tells you they expect some quarters ahead will run softer as new capacity ramps up and integration costs flow through.

Discipline on guidance in a company running at 23% return on capital is worth more than one blowout quarter.
