About this product
- <b>Reliable Fiber Testing</b>: Create a loopback test connection with this MPO Single Mode fiber loopback plug; Male MPO-12 connector for testing female MPO/MTP ports; Test 12-fiber MPO installations and QSFP transceivers for continuity
- <b>Accurate Test Performance</b>: Maintain precise loopback signaling with insertion loss below 0.35dB; Repeatability within 0.2dB ensures consistent results across multiple connections; Return loss above 50dB minimizes back-reflection for stable signaling
- <b>Built for Durability</b>: Optimized for multiple test cycles using high-precision ceramic ferrules in a compact ABS housing; Built in compliance with IEC and RoHS standards for reliable testing in regulated environments
- <b>Field-Ready Design</b>: Compact form factor is ideal for technicians performing on-site diagnostics and fault isolation; Quickly troubleshoot cables and verify performance in single mode MPO/MTP patch panels and transceivers; Includes protective dust cap
- <b>The IT Pro's Choice</b>: Our network tools and testers are rigorously tested in our Innovation Lab to ensure enterprise-grade reliability and durability; Built for quick diagnostics and routine maintenance across copper and fiber networks; Backed by free lifetime 24/5 multi-lingual technical assistance
Perform loopback testing and verify signal continuity across Single Mode MPO-12 fiber connections
This Single Mode MPO Loopback Plug is a practical tool for verifying signal continuity, insertion loss, and port function in fiber optic networks. Ideal for technicians and IT Pros, it enables fast, consistent testing across MPO-based fiber connections.
Test Single Mode Connections
This 9/125um MPO-12 Loopback Adapter is compatible with OS1 and OS2 cabling in point-to-point and structured installations. IEC and RoHS compliance ensures readiness for standardized deployments and testing in regulated environments.
Accurate Signal Diagnostics
Validate MPO transceivers, isolate faults, and confirm port behavior across high-speed parallel optic links. The fixed 12-fiber configuration with precision-aligned ferrules deliver clean signaling for accurate, reliable diagnostics.
For Enterprise Fiber Switches
The MPO-12 male connector attaches directly to female MPO/MTP ports for high-density testing without disrupting adjacent connections. A durable ABS housing withstands wear from repeated use and is suitable for frequent testing in data centers and edge or on-prem installations.
