OCS (Optical Circuit Switch)
Corporate & Tech💡 Key Takeaway: An all-optical switching fabric that redirects light beams using micro-electromechanical (MEMS) mirrors without optical-to-electrical conversions, slashing datacenter power.
Rotating Mirror Analogy: Instead of stopping every car at a toll gate to inspect IDs and reroute them electrically, OCS physically angles high-precision mirrors to bounce uninterrupted laser beams straight to their destination.

☕ Show-off Tip: 'Google supercharged its TPU superclusters using Optical Circuit Switches. Directing raw photons with MEMS mirrors cuts network power by 40% and future-proofs speeds beyond 1.6 Terabits.'
📖 Beginner-Friendly Explanation
STEP 1
Core Concept & Meaning
OCS (Optical Circuit Switch) is a native optical switching system that dynamically routes light signals across datacenter networks using micro-electromechanical systems (MEMS) 2D/3D mirrors without performing optical-to-electrical-to-optical (O-E-O) conversions.
Traditional digital packet switches consume massive electricity decoding and forwarding electrical packets. OCS maintains signal integrity entirely in the photonic domain.
STEP 2
Why It Matters & Mechanism
- Protocol & Bit-Rate Agnostic: Since it physically steers photons with mirrors, the switch hardware remains compatible whether data rates scale from 800G to 3.2T.
- 40% Network Power Reduction: Eliminating transceivers and packet-processing ASICs at the optical core slashes overall cluster energy draw.
- Proven at Hyperscale: Google famously anchored its TPU v4/v5p AI supercomputing fabrics on custom OCS platforms to dynamically reconfigure training topologies.
STEP 3
Practical Investment Tips & Pitfalls
Target photonic component fabricators and precision MEMS optical mirror designers. Note that mechanical switching latency (–milliseconds) suits topology scheduling rather than single-packet switching.
📊 OCS Photonic Power Savings Formula
Power Savings (%) = [ (P_OEO - P_OCS) / P_OEO ] × 100
