Product Description

The KEXINT 24196 is a high-density MMC (Very Small Form Factor) 2-port fiber optic adapter engineered with US Conec TMT ferrule technology for next-generation data center and telecom interconnect applications. Configured as straight-through (Sr-Sr), the adapter delivers reliable, low-loss optical coupling between MMC multi-fiber connectors — fully compatible with both single-mode (SM) and multimode (MM) fiber cables up to 2.5 mm in outer diameter.

A green-colored housing enables rapid port identification in densely loaded patch panels, while the reduced-flange mounting design optimizes rack space utilization — critical for hyperscale and edge-compute environments where every millimeter of panel real estate counts.

Each unit ships with two dust plugs to shield the precision alignment sleeves from contamination when ports are idle, preserving stable, long-term optical performance. Built around zirconia ceramic alignment sleeves, the KEXINT 24196 achieves insertion loss performance compliant with IEC 61753-1 Class B standards.

Manufactured by Shenzhen Kexint Technology — an ISO-certified fiber optic specialist with nearly a decade of industry experience — this adapter provides a cost-effective, production-ready solution for AI/ML data centers, 5G fronthaul and backhaul networks, and enterprise fiber backbone systems demanding maximum port density without signal integrity compromise.


Product HighLights

1. US Conec TMT Ferrule — Carrier-Grade Optical Precision At the core of the 24196 sits US Conec's proven TMT ferrule technology, delivering sub-micron fiber alignment and repeatable ≤0.35 dB insertion loss across the full −40 °C to +85 °C operating range. This is the same ferrule platform trusted in Tier-1 hyperscale data centers, ensuring your interconnect layer meets IEC 61753-1 Class B from day one.

2. VSFF Density Without Compromise With a 2-port MMC footprint roughly one-third the size of a duplex LC adapter, the 24196 enables 3× higher port density in the same panel real estate. In a 1U 48-port scenario, that translates to 144 MMC fibers where LC would max out at 96 — critical for 400G SR8/DR4 and 800G breakout architectures where every RU counts.

3. Straight-Through (Sr-Sr) — Zero Polarity Guesswork Unlike angled or keyed variants that demand careful polarity mapping during deployment, the Sr-Sr configuration ensures fibers pass straight through. Field technicians can patch with confidence — no polarity flip, no documentation headaches, and significantly fewer MAC (moves/adds/changes) errors in live production environments.

4. Green Housing — Instant Visual Identification Under Load In a fully populated 48-port patch panel, distinguishing individual adapter ports under dim data center lighting is a real operational pain point. The 24196's green housing creates an immediate visual anchor — technicians can identify MMC interconnect ports at a glance, slashing troubleshooting time and reducing the risk of accidental disconnection during maintenance windows.

5. Zirconia Ceramic Sleeves Rated for 500+ Matings The alignment sleeves are machined from zirconia ceramic (ZrO₂), not polymer alternatives. This material choice delivers three advantages: thermal expansion matched to the glass fiber over the full temperature range, surface hardness that withstands 500+ mating cycles without measurable degradation, and dimensional stability that holds insertion loss flat across the adapter's entire service life — a meaningful TCO differentiator in high-churn colocation environments.
