Selection guides, technology explainers and market analysis for optical interconnect — written for network engineers and sourcing teams.
GPU clusters doubled optical port demand per rack. Here is what that means for your transceiver selection.

Distance decides reach, fiber decides wavelength. A four-step method for picking 10G optics.

How the most common two-tier data center fabric maps onto 25G and 100G optics.

Both reach 400G. The difference is what happens at 800G.

Core size decides distance. Distance decides cost. Start here.

One fiber instead of two — as long as you get the pairing right.

Eighteen channels or eighty — the choice depends on distance and amplification.

Copper wins under three metres. Beyond that, the maths changes.

Five parameters, read over I²C, tell you more about link health than any alarm log.

Temperature does not just stress the module — it moves the wavelength.
View Details
Symmetric or asymmetric is the decision that drives everything downstream.
View Details
As speeds rise, power becomes the constraint that decides the architecture.

The module is not "incompatible" — it is speaking a different dialect.

Demand is concentrating at the high end. Lead time planning now matters more than price negotiation.
