In order to obtain accurate and repeatable results measuring insertion and return loss, the reference connector needs to outperform the connector under test. Reference cables from OptoTest are manufactured with reference ends that are certified to exceed the FOTP171A (A2.2.1) standard.
The HPR series of reference cables are offered with connectors for FC, SC, ST and LC with PC (UPC) or APC polish. The source end meets the standard requirements for PC or APC polish.
Hybrid cables are available where the source end has a different connector than the reference end. For example, an HPR-FP-SA-S refers to a single mode reference cable with an FC/PC connector at the source end and an SC/APC connector at the reference end.
HPR cables also available with MTP connectors, click here for more information.
