FAQs
Q1: What is an MMC connector, and how does it differ from MPO/MTP? MMC (Miniature Multi-fiber Connector) is a VSFF (Very Small Form Factor) multi-fiber connector developed by US Conec. Unlike traditional MPO/MTP connectors, MMC achieves 3× higher density — fitting up to 3 MMC ports in the same panel space as a single MPO — making it ideal for next-generation AI data center backplanes and 400G/800G parallel optic interconnects.
Q2: What does "Sr-Jr" mean? "Sr" stands for Senior (male) and "Jr" stands for Junior (female) in MMC terminology. An Sr-Jr adapter connects an MMC Senior (male) connector on one side to an MMC Junior (female) connector on the other, functioning similarly to a traditional fiber adapter but optimized for the MMC VSFF form factor.
Q3: Is this adapter compatible with standard MPO/MTP connectors? No. MMC is a proprietary VSFF interface from US Conec and is not physically compatible with MPO, MTP, LC, SN, CS, or MDC connectors. It requires genuine US Conec MMC cable assemblies for proper mating. All KEXINT MMC adapters use authentic US Conec alignment sleeves to guarantee precise ferrule alignment.
Q4: What fiber count does the MMC 4-Port Adapter support? Each MMC port supports a 16-fiber MT ferrule, meaning the 4-port adapter panel can terminate up to 64 fibers total when fully populated — delivering exceptional density for AI GPU cluster backplane interconnects.
Q5: What is the minimum order quantity (MOQ)? We offer a flexible MOQ to accommodate both trial orders and volume procurement. Contact our sales team with your target quantity for a customized quotation. Sample orders (1–10 units) are typically supported for evaluation purposes.
Q6: Do you provide test reports and certifications? Yes. Each batch ships with IL (Insertion Loss) and RL (Return Loss) test data upon request. We also support third-party testing (e.g., TIA, IEC) for large-volume orders. Our manufacturing facility is ISO 9001 certified.
Q7: What is the typical lead time? Stock items ship within 3–7 business days globally via DHL, FedEx, or UPS. Bulk OEM orders typically require 2–4 weeks depending on quantity and customization requirements. Expedited production is available for urgent projects.
Q8: Can you customize the adapter color, branding, or packaging? Yes. We support OEM silkscreen/logo printing, custom housing colors (beyond standard green), and tailored retail or bulk packaging. Our engineering team can also assist with custom panel configurations for specific rack designs.
Q9: What warranty do you offer? All KEXINT MMC adapters come with a 12-month manufacturer warranty against defects in materials and workmanship under normal use. Extended warranty options are available for long-term AI data center deployment contracts.
