ORL Testers and Attenuators


Keeping optical return loss (ORL) and attenuation in check is paramount to network service providers looking to maximize the quality of service (QoS).

EXFO’s state-of-the-art ORL and attenuation testers efficiently assess backreflection and empower operators working in FTTx/PON or CATV environments to better control and limit its impact on overall network power loss, bit error rate (BER) or signal-to-noise ratio (SNR).
