The Foundation of your Optical Access Network

Switching platforms are reaching 800G faster than servers and optics can follow. Explore how 2×400G bridges that gap—delivering two independent 400G links from a single 800G port—and why it marks a practical step along the road toward native 800G.

When fiber between sites runs short, adding more isn't always an option. This article explores how optical circulators let transmit and receive signals share a single strand, opening the door to 400G interconnects over half the fiber — and barely any rack space.

At 800G and 1.6T, choosing high-speed copper is no longer just about reach. Explore how link reliability, cable thickness, airflow and power shape the trade-offs between DAC, ACC and AEC — and why the right link matters more than the most advanced one.
