Product profile

The compact push-pull connector of 8 Fiber MTP MPO Loopback Test Cablesets a high standard for all QSFP and QSFP+ modules, capable of handling fiber loopback testing for 10Gb, 40GB, and 100GB rates with single-mode QSFP and QSFP+ transceivers.

Precision termination is also a major feature of the MPO Loopback Test Cable.


MPO Loopback Test Cable built-in optical fiber is precisely terminated and aligned, which ensures the accuracy of signal transmission during testing and greatly reduces the possibility of signal loss. This precision performance makes MPO Loopback connectors perform particularly well in critical applications, especially in demanding environments.

Protective design is also an important feature of the MPO Loopback Test Cable. Usually, these cables are equipped with additional protective shells or sheaths to effectively protect the connector itself and the optical fiber cable from physical damage and external pressure. This design ensures the long-term use of the equipment and reduces maintenance costs.
