MPO Loopback
LC/UPC OM3 2.0mm Fiber Optic Loopback with Pull Tab
The BWNFiber LC/UPC OM3 2.0 mm Fiber Optic Loopback with Pull Tab provides a multimode optical return path for LC ports used in enterprise and data-center equipment. The compact 2.0 mm body and pull tab allow quicker mate/demate in dense multimode panels, while OM3 fiber supports short-reach multimode transceiver and switch-port verification. It replaces temporary jumpers during isolated port testing and is 100% factory optically tested.

Selection Guidance
- Choose this model when testing OM3-designated LC ports and short-reach multimode optics (e.g., 10GBASE-SR class).
- For OM4 ports use the corresponding OM4 series to keep test conditions aligned with the link grade.
- Pull-tab version is preferred in high-density panels where standard LC loopbacks are hard to extract safely.
- Specific requirements (labeling, packaging) are confirmed at inquiry/order stage.
Applications
- OM3 LC port and SFP/SFP+ multimode testing
- High-density multimode panel verification
- Enterprise switch and server interface diagnostics
- Production QA with frequent connect cycles

FAQ
Frequently Asked Questions
Is this loopback only for OM3?
This model is specified for OM3. For OM1/OM2 legacy multimode, use the standard LC multimode loopback series.
Why use a pull tab on an LC loopback?
In dense patch panels the tab improves extraction force control and reduces accidental disturbance of neighboring LC connectors.
What is the insertion loss?
≤ 0.5 dB at 850 nm.
Do you offer OM4 or other multimode grades with pull tab?
