Fiber Optic Loopbacks

We offer a great selection of fiber-optic loopback connectors in single mode, multimode, 50/125, 62.5/125, and all of the connector options an engineer could want. Don't find yourself on a jobsite needing to test an SFP module or Cisco XENPAK module and not having a simple fiber-optic loop back module. If you do not see the module that you need, please contact us and we will make it for you.
