Reliability

Definition

Reliability refers to the ability of a system or component to consistently perform its intended function without failure over a specified period of time. In optoelectronic integration, reliability is crucial as it affects the performance, lifespan, and overall effectiveness of optoelectronic devices in various applications. High reliability ensures that systems operate effectively in real-world conditions, leading to increased trust from users and lower maintenance costs.
