What Is AI Data Center Optical Interconnect

By C-LIGHT Marketing 丨 Sep 15, 2026

AI data center optical interconnect enables high-bandwidth, low-latency communication between GPUs, switches, servers, and racks using 400G, 800G, and 1.6T optical technologies.

Why Does 100G ER4 Link Fail at 40km?

By C-LIGHT Marketing 丨 Sep 14, 2026

100G ER4 link can fail at 40km due to fiber loss, connector loss, dispersion, optical power limits, and insufficient link margin.

What Is CWDM?

By C-LIGHT Marketing 丨 Sep 13, 2026

CWDM (Coarse Wavelength Division Multiplexing) combines multiple optical wavelengths on a single fiber to increase capacity, using wide 20 nm channel spacing for cost-effective metro, access, and enterprise networks.

What Is BOSA?

By C-LIGHT Marketing 丨 Sep 12, 2026

BOSA (Bi-directional Optical Sub-Assembly) combines optical transmit and receive functions in one compact assembly for bidirectional communication over a single fiber, widely used in PON and optical access networks.

What Is FEC?

By C-LIGHT Marketing 丨 Sep 11, 2026

FEC (Forward Error Correction) is a key technology in high-speed optical networks that corrects transmission errors without retransmission, improving link reliability for 100G, 400G, 800G, and 1.6T systems.

What Is a DAC Cable?
