By “looping back” the connections from the transmit pairs to the receive pairs in network devices, the MTP Loopback creates a complete optical link. This allows you to evaluate the performance of specific components of a network, or the complete link in a network path.
Male and female connector types are available. Choose between standard, 'Elite' and 'Super Elite' ferrule styles to minimize insertion loss and provide better testing performance.
