RIN (Relative Intensity Noise) measures fluctuations in laser optical power and is an important parameter for high-speed optical transmitters and optical communication systems

What Is OSNR?

By C-LIGHT Marketing 丨 Jul 18, 2026

OSNR (Optical Signal-to-Noise Ratio) measures the ratio of optical signal power to noise power and is a key performance parameter in DWDM and coherent optical networks.

What Is Pre-FEC BER?

By C-LIGHT Marketing 丨 Jul 17, 2026

Pre-FEC BER is the bit error rate measured before Forward Error Correction, showing the raw error performance of a high-speed optical communication link.

What Is Post-FEC BER?

By C-LIGHT Marketing 丨 Jul 16, 2026

Post-FEC BER is the bit error rate measured after Forward Error Correction, showing the residual error performance of a high-speed optical communication link.

How Does Silicon Photonics Work?

By C-LIGHT Marketing 丨 Jul 15, 2026

Silicon photonics uses silicon-based photonic circuits to generate, modulate, route, and receive optical signals, supporting high-speed data transmission in modern data centers and AI networks.

What Is Receiver Sensitivity

By C-LIGHT Marketing 丨 Jul 14, 2026

Receiver sensitivity is the minimum optical power required by a receiver to achieve a specified performance, making it a key parameter for optical link distance and reliability.

What Is Insertion Loss?

By C-LIGHT Marketing 丨 Jul 13, 2026

Insertion loss is the optical or electrical power lost when a signal passes through a component, connector, cable, or transmission link.

What Is Transmitter Optical Power?

By C-LIGHT Marketing 丨 Jul 12, 2026

Transmitter optical power is the optical power launched into the fiber by an optical transmitter, affecting link budget, transmission distance, and receiver performance.
