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.

An optical transceiver is a compact, hot-pluggable device that enables bidirectional data transmission over fiber optic cables. It’s the critical bridge between the electrical signals in network equipment (like switches, routers, and base stations) and the optical signals used in fiber networks. In telecom, they are key to delivering high-speed, long-distance communications.
