The fiber optic loopback attenuator is made based on regular fiber optic loopback plug, adopting special optical fiber to achieve a specific attenuation level for fiber loopback testing. This kind of attenuated fiber loopback plug is designed for testing, engineering and provisioning fiber optic network links.
Arkoptics offers both singlemode and multimode LC loopback plugs available with attenuation level from 1dB to 30dB. It provides a direct connection between transmitter and receiver ports by looping back without the need for additional fiber cable or in-line optical attenuator, making it ideal for testing and troubleshooting telecom and datacom networks.
Our inventory LC fiber loopback modules are available in singlemode 3dB, 5dB, 12dB, 15dB, 20dB, 22dB and multimode 1dB, 2dB, packed in color-coded rigid housing shell. If you are looking for a reliable, effective fiber loopback tester to maintain and optimize your network performance, our attenuated LC loopback modules will be your best choice.
