R&M, the globally active Swiss developer and provider of high-end infrastructure solutions for data and communications networks, has retested its MPO fiber optic connectors using testing guidelines that it has followed for years. According to Dr. Hannes Grubinger, CPMO at R&M, the company’s current standardized tests demonstrate that its globally available MPO-QR connectors consistently reach market-leading benchmarks.
Recent test results also show that the MPO-QR and MTP® connector variants are 100% compatible and comparable. R&M says its MPO-QR connectors transmit light signals reliably and deliver ultra-low-loss performance to support increasing transmission rates in fiber optic networks, including AI data centers.
Why MPO Connector Test Results Matter
For buyers and users of fiber optic connectors, understanding the difference between insertion loss and return loss measurements is becoming increasingly important. MPO and MTP® connectors serve as important links in high-density fiber optic networks used in data centers, Internet hubs and broadband infrastructure.
Precision is particularly important for these multiple fiber connectors because up to 24 fibers need to be routed in parallel across a 16-square-millimeter endface and aligned with micrometer-level accuracy.
Comparing MPO and MTP® Connectors
MPO and MTP® are two multiple fiber connector options with different capacities. R&M notes that several factors can be considered when selecting between the two, including housing material, manufacturing process, polarity change solutions, guide pin design and robustness, planned transmission distances, bandwidths, fiber densities, scaling requirements, mating cycles, local operating conditions and budget.
Following its recent tests, R&M concludes that high-end MPO and MTP® connectors can achieve identical values, making both connector types suitable options for fiber optic networks.
MPO connectors are considered low-cost and versatile and are suitable for data center applications. R&M says its quality monitoring helps ensure that MPO-QR connectors consistently achieve a high quality grade. MTP® connectors, meanwhile, are characterized by robust reliability, twist-safe guide pins and durability.
R&M Offers Both MPO-QR and MTP® Cable Assemblies
R&M offers cable assemblies featuring both connector types. These include MTP® connectors from USConec and high-end MPO-QR connectors manufactured in-house. According to R&M, both variants meet the high optical requirements for data center cabling.
The company’s MPO-QR connectors also feature quick-release operation, an MPO ferrule with a floating mount, MDoD with a QR code on the measurement log, and optional monitoring through the inteliPhy tag.
Leadership Comment
In the test, the MPO-QR multiple fiber connector from R&M delivers attenuation values that match those of top products on the fiber optic market. The QR plug-in mechanism is operated via the strain relief sleeve. This makes it easier to access the connectors in high-density patch panels. – Dr. Hannes Grubinger, CPMO at R&M.
R&M’s latest testing reinforces its position that both MPO-QR and MTP® connectors can deliver comparable performance when used in high-end fiber optic network applications.
