How Does 100G ER4 Achieve 40km Transmission?

By C-LIGHT Marketing 丨 Aug 2, 2026

100G ER4 uses four LAN-WDM wavelengths and advanced optical components to provide 100Gbps transmission over up to 40km of single-mode fiber.

How Does LPO Work?

By C-LIGHT Marketing 丨 Aug 1, 2026

LPO (Linear Pluggable Optics) connects the host switch ASIC directly to linear optical components, reducing DSP power and latency for high-speed data center links.

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.
