MPO Loopback
MPO 8F/12F/24F OM4 2.0mm Fiber Optic Loopback with Pull Tab
The BWNFiber MPO OM4 2.0 mm Fiber Optic Loopback with Pull Tab combines OM4 multimode multi-fiber performance with an integrated extraction tab for high-density environments. Available in 8F, 12F and 24F, it supports parallel-optics port testing where standard housings are hard to grip. The pull-tab design improves insertion and removal in crowded MPO panels while maintaining the optical return path needed for module and switch verification. Units are 100% factory optically tested prior to shipment.

Selection Guidance
- Use the pull-tab version when MPO ports are tightly packed and standard housings are difficult to insert or remove safely.
- Polarity and gender/pin configuration are confirmed per customer requirement at inquiry or order stage.
- Compatible with typical parallel-optics interfaces when fiber count matches the active lanes.
- For standard housing (non-pull-tab) or other fiber grades, refer to the Fiber Optic Loopback Series.
Applications
- High-density OM4 MPO panel testing
- Parallel-optics module verification in crowded racks
- Data-center maintenance with frequent reconnects
- 40G / 100G / 400G SR multimode diagnostics
- Production and field multi-fiber testing

Why Source from BWNFiber
Pull-tab MPO loopbacks address a practical pain point in dense racks: access. By pairing OM4 optical performance with improved extraction design, test and maintenance teams can verify parallel-optics ports with less panel disruption and more consistent handling.

FAQ
Frequently Asked Questions
When should I choose the pull-tab MPO loopback?
Use it when MPO ports are tightly packed and standard housings are difficult to insert or remove safely.
Does the pull tab change optical performance?
No. Optical limits remain defined by the fiber and connector specification; the tab is a handling feature.
Is polarity configurable?
Polarity and pin configuration are confirmed with the customer at inquiry/order stage according to the equipment under test.
What fiber counts are available?
8F, 12F and 24F.
