High-frequency stock traders turn to laser networks, to make yet more money

“Financial traders are now turning to high-speed laser networks between stock exchanges, to decrease latency by a few milliseconds, to squeeze a few more trillion dollars per year out of high-frequency trading (HFT).  Perseus Telecom recently completed a microwave link between London and Frankfurt that reduced the round-trip latency to just 4.6 milliseconds — almost halving the 8.35-millisecond round-trip for the London-Frankfurt fiber link.  The microwave network cost between $13 and $26 million to build, but for the financial trader who uses it could earn billions.”
