About the Anritsu S331L
As a network cable analyzer instrument, the Anritsu S331L is designed for demanding applications. Specifically, network cable analyzers certify and troubleshoot copper and fiber optic network cabling by measuring crosstalk, return loss, insertion loss, and propagation delay. Accurate and reliable performance is essential — measurement drift or component failure can cause costly errors, compliance issues, and project delays.
