Fiber testing and inspection is a critical step to verifying network performance, to comply with standards and warranty requirements, and a tool to diagnose, repair and re-verify a network once it’s been activated. The need for accurate testing has been exacerbated by diminishing loss budgets and increased demands on networks.
High losses and optical network failure are often caused by contaminated, damaged or poorly polished connectors, poor splices, and micro or macrobends introduced in shipping or installation. The best way to keep your network running efficiently? Test and inspect.
Fiber Testing FAQs
What’s the difference between Tier 1 and Tier 2 Testing?
Tier 1 testing looks at loss, length and polarity. While Tier 1 fiber optic tests can identify problems in terms of pass or fail, they cannot determine the root cause or location of the problem. Tier 2 fiber optic testing is used to pinpoint root-cause locations and the amount of loss and optical return loss (ORL) from each problem contributor and is performed selectively in addition to Tier 1 testing under specific conditions and situations. Tier 2 fiber testing provides a deeper level of link visibility unlike any other fiber infrastructure tests. The optical time-domain reflectometer (OTDR) is used to perform Tier 2 fiber optic testing.
