Do you know how we handle a connector that fails testing?

At Rayoptic, every Hardened SC/APC flat drop patch cable is 100% tested for insertion loss and return loss before shipment.

If a connector is out of specification, it will be labeled, cut off, and scrapped — not shipped to the customer.

Quality control starts from every single connector.
