The KEXINT 24253 MMC 4-Port Adapter (Sr-Sr, Green) is a precision-engineered Very Small Form Factor (VSFF) fiber optic interconnect solution designed for next-generation hyperscale data centers and AI-driven high-performance computing (HPC) infrastructures. Manufactured by Shenzhen Kexint Technology Co., Ltd. — a trusted China-based fiber optic supplier — this adapter delivers carrier-grade optical alignment and exceptional port density for 400G, 800G, and emerging 1.6T transmission environments.
Featuring a Senior-to-Senior (Sr-Sr) mating configuration, the 24253 enables seamless, low-loss interconnection between MMC-12, MMC-16, and MMC-24 connector types. Its green color-coded housing ensures instant visual identification in high-density patch panels, while the reduced flange design allows tight side-by-side mounting with minimal clearance — maximizing rack space utilization in space-constrained data center environments.
Each unit is shipped with four dust plugs pre-installed, protecting the adapter ports from contamination during transport, installation, and idle periods. Constructed from high-durability engineering-grade materials with rigorously controlled mechanical tolerances, the KEXINT 24253 ensures consistently low insertion loss and superior return loss performance across thousands of mating cycles.
Key applications include high-density fiber distribution frames (ODF), MMC patch panels, AI cluster interconnects, and hyperscale spine-leaf architectures where every millimeter of rack space counts.
Product Description
Shenzhen Kexint Technology Co., Ltd. is a professional fiber optic manufacturer and supplier based in Shenzhen, China, specializing in VSFF interconnect solutions for hyperscale data centers and AI infrastructure. Our KEXINT 24253 MMC 4-Port Adapter is engineered and manufactured in-house to deliver the port density and optical performance that 800G and 1.6T networks demand — all at factory-direct pricing with flexible OEM/ODM support.
Product Highlights
1. 4-Port VSFF Density in a Reduced Flange Body — Packs four Senior-to-Senior MMC connections into a footprint smaller than a single duplex LC adapter. Zero-gap side-by-side mounting maximizes every rack unit in hyperscale and AI data center panels.
2. Full MMC Connector Ecosystem Compatibility — One adapter supports MMC-12, MMC-16, and MMC-24 connector variants, covering single-mode and multimode paths for 400G, 800G, and 1.6T transmission — no need to stock multiple adapter types.
3. Precision Zirconia Ceramic Sleeves for Low-Loss Performance — Factory-aligned ceramic sleeves deliver ≤ 0.35 dB typical insertion loss and ≥ 55 dB return loss (SM APC), tested across 500+ mating cycles to ensure signal integrity in mission-critical links.
4. Factory-Direct from a Verified Chinese Manufacturer & Supplier — ISO 9001-certified in-house manufacturing with 100% IL/RL batch testing. OEM/ODM-ready for custom colors, private labeling, and tailored packaging — competitive wholesale pricing with no middlemen.
5. Rugged, Field-Ready Design with Pre-Installed Dust Protection — Engineered polymer body rated for -40°C to +85°C operation. Each of the four ports ships with a dust plug pre-installed, protecting optical interfaces through shipping, storage, and installation.
