What is a Loopback Transceivers ?
If you ever wondered how to test the ports of your switches or serves, the answer is using a loopback transceiver ! It’s the simplest way and most low cost solution on the market for ports testing.
The best solution for testing switches and servers ports is the passive electrical loopback transceiver. It works by simulating the communication between two devices by transmitting the data (output) and receiving it (input).
Loopback perfectly replicate the performance of typical 10G SFP+, 40G QSFP+, 25G SFP28, 100G QSFP28 and 400G QSFP-DD connections between equipped adapter cards, blade servers, routers, and switches. Even if they are able to duplicate the operational characteristics of typical transceivers, they do not contain the expensive components found in transceivers, such as the chips or laser diodes. That is why the cost of loopback is so low.
Optech‘s Loopback Transceivers serie includes, 10G SFP+ Loopback, 40G QSFP+ Loopback, 25G SFP28 Loopback,100G QSFP28 Loopback and 400G QSDFP-DD Loopback.
