Products / 1.6T 2×FR4 2 km
Overview
1.6T over four fibers: two 800G FR4 ports, each carrying four 200G wavelengths on one duplex pair, for links up to 2 km between halls or buildings.
In our September 26, 2026 check, a large webstore showed 16 units of this part in global stock, one of the thinnest 1.6T supplies we saw. Every quote states lead time.
Typical uses
- 1.6T building-to-building links up to 2 km
- Fiber-scarce campuses moving to 200G lanes
- Two 800G FR4 ports from one 1.6T cage

What it costs elsewhere
Lowest public single-unit price in each channel, new modules, read from public web pages on September 25–28, 2026. US channel brands are TAA-compliant with lifetime warranties; ours are not TAA-compliant. Asia-shipped prices exclude US import duty and freight. Method and full ranges: price index.

Questions
Why FR4 at 1.6T?
Because it needs four fibers per 1.6T link instead of sixteen. Between buildings, spare fiber usually costs more than the optics.
What does it link to?
Another 1.6T 2×FR4, or two 800G FR4 modules, one per port.
Why is there no published price?
We have sample pricing only for 1.6T. Project quotes reflect volume pricing agreed with the factory per order.
