Technical Specifications
Engineered For Performance
Precision Ceramic Ferrule
High-quality zirconia ceramic ferrule ensures accurate fiber alignment and consistent optical performance across repeated test cycles.
Compact Molded Design
Durable molded connector housing protects the internal fiber loop, providing a compact and portable solution for field and lab testing environments.
Multi-Mode Compatibility
Available in single mode 9/125 and multimode 50/125 (OM2/OM3) and 62.5/125 (OM1) fiber options to match any network infrastructure under test.
Low Insertion Loss
Typical insertion loss of 0.3dB or less ensures accurate test measurements without introducing significant signal degradation into the loopback path.
Typical Applications
Transceiver & SFP Module Testing
Verify SFP, SFP+, and XFP transceiver module functionality by looping the transmit signal back to the receive port for bit error rate and power level testing.
Network Diagnostics
Isolate faults in fiber optic links by confirming port-level connectivity on switches, routers, and media converters during network troubleshooting.
Equipment Burn-In Testing
Perform extended burn-in and quality assurance testing on fiber optic equipment during manufacturing and pre-deployment validation.
