MPO Loopback
MTP® 8F/12F/24F OM4 Fiber Optic Loopback
The BWNFiber MTP® OM4 Fiber Optic Loopback provides a multi-fiber optical return path for OM4 multimode MTP interfaces. Offered in 8F, 12F and 24F standard housings, it supports high-density parallel-optics testing for data-center switches, NICs and optical modules. The assembly enables isolated TX/RX verification without external trunk cables, helping production and lab teams accelerate port-level diagnostics. OM4 fiber and UPC MTP-compatible interfaces are paired with 100% factory optical testing for consistent results.

FAQ
Frequently Asked Questions
MTP or MPO — which should I order?
Choose the series that matches the connector system on your equipment. This page is for MTP®-compatible OM4 interfaces; MPO OM4 loopbacks are listed separately.
What distances or modules is OM4 used for?
OM4 is commonly used for short-reach multimode parallel optics such as 40G/100G SR-class links. Match the loopback grade to the port specification.
Do you offer pull-tab MTP versions?
Pull-tab options are available in the MPO pull-tab series. Ask sales if you need MTP-compatible pull-tab handling.
How do I select 8F vs 12F vs 24F?
Select the fiber count that matches the optical interface under test.
