Swap-Out connector

The new line of FTBx 700D OTDR modules comes with a Swap-Out connector which can easily be changed, as and when needed, without having to send the test module to a service center. This ensures optimal performance over time without undue maintenance costs and downtime. The OTDR's optical connector health can be checked with an onboard diagnostic tool to replace the connector only when necessary.

Did you know?

Was your OTDR connector damaged when connecting a UPC cable to the APC port on your device? This no longer needs to cause downtime by sending the device back for repair. Thanks to EXFO’s Swap-Out connectors, you can now check connector health instantly and replace your connector within seconds if needed–directly from the field! See it for yourself.
