The demand for higher data rates in data centers and enterprise networks drives the adoption of 400G technology. Among the key components enabling this speed are QSFP-DD cables. Two common types are Active Optical Cables (AOC) and Direct Attach Copper (DAC) cables. Understanding their differences helps in selecting the right solution for specific network needs. Overview of QSFP-DD Cable Types QSFP-DD (Quad Small Form-factor Pluggable Double Density) is a high-speed interface

A QSFP28 100G single-wavelength module delivers 100 Gbps over one optical lambda using PAM4 modulation, instead of spreading traffic across 4 wavelengths like CWDM4/LR4.

DWDM optical transceivers transmit data using tightly spaced wavelengths (channels) on a single strand of single-mode fiber, allowing dozens or even hundreds of high-capacity signals to travel simultaneously over long distances.
