FAQ
What type of fiber does this loopback plug support?
This loopback plug supports single mode 9/125 fiber, which is commonly used for long-distance and high-bandwidth applications in data centers and telecommunications networks. Single mode fiber provides lower signal attenuation and higher bandwidth compared to multimode fiber, making this tool suitable for testing critical network infrastructure where signal integrity is paramount.
What MPO connector type does this loopback plug use?
It uses an MPO-8 female connector designed to test male MPO interfaces with fixed alignment pins. The MPO-8 configuration supports 8 fibers, allowing comprehensive testing of MPO/MTP cables, patch panels, and transceivers. This connector type is standard in high-density fiber optic installations where space efficiency and reliable connections are essential.
What are the key performance specifications for this loopback plug?
Key performance specifications include insertion loss below 0.35dB, return loss above 50dB, and repeatability within 0.2dB. These metrics ensure accurate and consistent test results by minimizing signal degradation and back-reflection. The low insertion loss preserves signal strength during testing, while the high return loss reduces interference for stable loopback signaling in network diagnostics.
Is this loopback plug compliant with industry standards?
Yes, it is built in compliance with IEC standards and meets RoHS (Restriction of Hazardous Substances) environmental requirements. It is also TAA (Trade Agreements Act) compliant, making it suitable for use in government and regulated procurement environments. These compliances ensure the tool meets quality and safety standards for reliable testing in professional network installations.
What are the physical dimensions and weight of this loopback plug?
The loopback plug measures 0.80" wide by 0.30" high (20.32 × 7.62 mm) and weighs 0.10 oz (2.83 g). Its compact and lightweight design makes it highly portable for field technicians, easily fitting into toolkits or pockets. The small footprint does not compromise durability, as it features a robust ABS housing that withstands frequent use in testing scenarios.
What is included with this loopback plug for field use?
The loopback plug includes a protective dust cap to prevent contamination of the MPO connector when not in use. This accessory helps maintain connector cleanliness and performance integrity during transport and storage. The dust cap is essential for field technicians who need to ensure reliable connections when performing on-site diagnostics in various environments.
