Features
40G QSFP+ Loopback Module for Testing
This low-profile passive QSFP+ 40G loopback cable features typical insertion loss (attenuation) characteristics of a mere 0dB, consuming no more than 0.0 Watts of power during the testing process.
Power Consumption
0W
Attenuation
0dB
Max Data Rate
40Gbps
Make Port Testing Easier and More Efficient
Compared with traditional loopback testing where modules are connected to jumpers, loopback modules are simpler and more efficient in port testing, allowing you to check port operating status by simply plugging in the switch.
No Compatibility Restrictions
The loopback transceiver is compatible with all QSFP+ ports and can be widely used in switch NIC router and other equipment testing, R&D validation, and field analysis.

Very powerful loopback modules. These modules came in time with a secure package. I have used them in testing 40G QSFP ports on my cisco switches and I admit it is a great way to test QSFP connectivity on cisco switches. I’m quite satisfied with them.

I’d like to give these loopback modules five stars because they really bring me a very good user experience. If I have other needs, I will still choose FS. They do a good job.

The items I ordered arrived very quickly and work perfectly. I will be using Fiberstore as my primary fiber network resource from now on.
