How Does CPO Work?

By C-LIGHT Marketing 丨 Jul 31, 2026

CPO (Co-Packaged Optics) integrates optical engines with the switch ASIC in the same package, reducing electrical interconnect distance and improving power efficiency for high-speed data centers.

What Is PAM4?

By C-LIGHT Marketing 丨 Jul 30, 2026

PAM4 is a four-level signaling technology that transmits two bits per symbol, enabling higher data rates for 400G, 800G, and 1.6T optical networks.

What Is an Optical DSP?

By C-LIGHT Marketing 丨 Jul 29, 2026

An optical DSP processes high-speed electrical and optical signals in transceivers, providing equalization, signal recovery, and performance optimization for 400G, 800G, and 1.6T networks.

What Is FEC in Optical Communication?

By C-LIGHT Marketing 丨 Jul 28, 2026

FEC (Forward Error Correction) improves optical link reliability by detecting and correcting transmission errors, supporting high-speed 100G, 400G, 800G, and 1.6T networks.

How Does DWDM Work?

By C-LIGHT Marketing 丨 Jul 27, 2026

DWDM (Dense Wavelength Division Multiplexing) combines multiple closely spaced wavelengths on a single optical fiber to increase transmission capacity over long-distance networks.

What Is Data Center Interconnect?

By C-LIGHT Marketing 丨 Jul 26, 2026

Data Center Interconnect (DCI) connects separate data centers using high-speed optical networks, enabling reliable, scalable data transmission for cloud, AI, and enterprise infrastructure.
