MPO-12F Loopback Module – Low Insertion Loss for Precise Network Testing
Product Summary: The MPO-12F Loopback is a 12-fiber MPO loopback module designed for testing and commissioning of MPO-based fiber optic networks. With insertion loss ≤0.7dB (8F/12F) and return loss ≥65dB (SM), it ensures accurate signal loopback during data center validation and equipment certification. Built with ceramic/MTP ferrules and rated for ≥100,000 mating cycles, it provides reliable, repeatable performance for high-density environments.
Key Selling Points
- ≤0.7dB Low Insertion Loss: Ensures minimal signal attenuation for accurate test results, reducing measurement uncertainty in MPO link certification.
- ≥65dB Return Loss (SM): Excellent back reflection control, critical for high-speed and DWDM network testing to prevent signal interference.
- ≥100,000 Mating Cycles: Durable ceramic ferrule and precision alignment design ensure long service life in frequent plug-and-test scenarios.
- Support OS2/OM1-5 Fiber Types: Flexible compatibility with single-mode and multimode networks, covering diverse testing needs from SM to OM5 broadband.
- Link Failure Rate <0.1%: High reliability reduces the risk of false failures during automated testing sequences.

FAQ
1. What is the difference between MPO and MTP loopback?
MTP is a brand of MPO connector with enhanced performance. Our loopback is compatible with both MPO and MTP interfaces.
2. Can this loopback be used for 40G/100G testing?
Yes, the 12-fiber MPO loopback supports parallel optics testing for 40GBASE-SR4 (8 fibers) and 100GBASE-SR10 (10 fibers), among others.
3. What is the warranty period?
We offer a standard 1-year warranty against manufacturing defects. Extended warranty available upon request.
4. Do you provide custom fiber type combinations?
Yes, we can supply loopbacks with mixed fiber types (e.g., SM + MM) for specific test setups.
5. Is the loopback compliant with TL9000?
Our manufacturing facility holds TL9000 certification, ensuring quality management in design and production.
6. What is the minimum order quantity (MOQ)?
Please contact our sales team for MOQ details as it varies by configuration.
7. Can I get a sample before bulk order?
Yes, samples are available. Contact us to discuss sample policy and lead time.
