The KEXINT 24895 MMC Jr Male Connector Kit (Single-Mode, MMC Elite, Green Housing) is a premium VSFF field-terminatable connector solution engineered by KEXINT, a trusted manufacturer and direct supplier of fiber optic interconnect products based in China. Built with US Conec genuine MMC Elite-grade ferrules, this Junior (Jr) Male connector kit delivers single-mode performance optimized for next-generation AI data center backplane interconnects, hyperscale spine-leaf fabrics, and high-density optical distribution frames.
The MMC Elite variant features ultra-precision 16-fiber MT ferrule geometry with sub-micron fiber alignment, enabling low insertion loss and high return loss for 400G/800G parallel optic links. The distinctive green housing provides instant visual identification in congested rack environments, while the field-installable kit design reduces deployment lead time compared to factory-terminated assemblies. Fully customized from China with flexible OEM branding, packaging, and cable assembly options, this connector kit delivers genuine US Conec interconnect quality at factory-direct pricing — the reliable choice for system integrators, telecom carriers, and AI infrastructure operators seeking scalable, high-performance single-mode MMC connectivity.
Product Description
KEXINT 24895 is a premium field-installable MMC Junior (Jr) Male connector kit engineered for next-generation AI data center and hyperscale optical interconnect deployments. Built around US Conec genuine MMC Elite-grade 16-fiber MT ferrules, this single-mode connector kit delivers sub-micron alignment precision, ultra-low insertion loss, and high return loss — making it the ideal building block for 400G and 800G parallel optic trunk cables, breakout assemblies, and high-density patch panels. The distinctive green housing ensures instant port-type identification in congested rack environments, while the field-terminatable design empowers on-site assembly, reducing deployment lead time versus factory-terminated alternatives. Fully customized from KEXINT in China, each kit ships with all necessary components — connector body, ferrule assembly, crimp sleeve, boot, and dust cap — ready for integration into your MMC cabling infrastructure.
Key Features
US Conec Genuine MMC Elite Ferrule — Authentic US Conec MMC Elite 16-fiber MT ferrule with precision-molded guide pin holes, delivering consistent sub-0.35 dB insertion loss (typical) and >55 dB return loss (APC) for single-mode 400G/800G parallel optic links.
VSFF Junior (Jr) Male Form Factor — Compact Jr interface (shorter than Senior variant) enables ultra-high-density patching in AI GPU cluster backplanes, spine-leaf switch fabrics, and 1U/2U ODF panels where every millimeter of rack space counts.
Single-Mode Optimized (G.657.A2 Compatible) — Precision-tuned for 9/125 μm single-mode fiber with G.657.A2 bend-insensitive compatibility, ensuring reliable performance in tight-radius routing typical of high-density fiber management trays.
Green Color-Coded Housing — MMC-standard green outer body provides at-a-glance port-type identification, reducing misconnection errors during live AI data center maintenance operations.
Field-Installable Kit Design — Complete kit includes pre-assembled connector body, MT ferrule assembly, crimp sleeve, strain-relief boot, and protective dust cap — compatible with standard MT fusion splicing or mechanical termination workflows.
Customized from China — Factory Direct — As a direct manufacturer and supplier, KEXINT supports full OEM customization: silkscreen logo printing, custom housing colors, tailored packaging, pre-terminated cable assembly service, and flexible MOQ for trial orders through volume OEM contracts.
