Single-Mode or Multimode Fiber? Compare the Complete Link Cost
Choose fiber by the optical application, route, installed channel and operating requirements. Neither single-mode nor multimode is universally the cheaper design.

SFP+ to QSFP28: What a 10G-to-100G Upgrade Actually Changes
A move from 10G SFP+ to 100G QSFP28 changes host interfaces and potentially the optical channel. Form factor alone does not establish link compatibility.

Reuse or Replace the Fiber? Assess the Installed Channel First
Before a data-center speed upgrade, inventory the full optical path and test it against the target interface rather than replacing—or reusing—fiber by assumption.

PoE, PoE+ and PoE++: Read the Power Budget at Both Ends
Understand PSE output, PD-available power, PoE types and shared switch budgets before choosing ports for access points, cameras or phones.

When an 800G Upgrade Makes Sense—and When It Does Not
Evaluate 800G against a demonstrated capacity or density need, qualified endpoints and a complete migration cost rather than assuming every network must advance.

High-Density 400G Is a Rack Design Problem, Not Just a Port Count
Evaluate usable 400G density with uplink allocation, failure domains, optical power, cable handling and maintenance access—not ports per rack unit alone.

GPU-Cluster Networking: The Communication Pattern Shapes the Fabric
Plan GPU networks around collective communication, placement and competing traffic. Link speed matters, but only within the complete host-to-host path.
