CWDM vs DWDM: Which Technology Should You Choose for Your Network?
CWDM is cheaper for short-haul access networks due to uncooled lasers (20nm spacing), while DWDM offers greater capacity and distance (>80km) for core links.

How Fast is Fiber Optic Speed, and What Components Define Its Limit?
Fiber optic speed is defined by the transceivers and cables used. We explain data rates from 10G to 800G, the role of modulation (PAM4), and why high-quality AOCs are key.
