MMC-16 Fiber Optic Jumper | VSFF High-Density 16-Fiber Patch Cord for 400G/800G Data Centers

The HOLIGHT MMC-16 Fiber Optic Jumper is an ultra-compact, high-performance cable designed for next-generation 400G/800G optical interconnects.
Equipped with US Conec MMC connectors on both ends, this VSFF jumper triples port density compared to traditional MPO/MTP systems while maintaining exceptional optical precision.
Featuring the DirectConec push-pull boot, it ensures effortless operation in tight spaces. The use of TMT Elite ferrule technology guarantees low insertion loss and high return loss across both OM4 multimode (Magenta) and OS2 single-mode (Yellow) variants.
Engineered for reliability, scalability, and safety, MMC-16 jumpers redefine density and efficiency in modern data center cabling.

Feature Details

1. VSFF Ultra-Compact Interface
   The MMC connector’s 3× higher port density allows more fibers per rack unit, achieving maximum utilization of limited cabinet space.
2. DirectConec Push-Pull Boot
   A revolutionary design enabling one-handed insertion and removal, simplifying access in high-density front panels.
3. TMT Elite Ferrule Precision
   Ensures industry-leading optical accuracy with ≤ 0.35 dB insertion loss and exceptional APC return loss up to 60 dB.
4. Dual-Mode Compatibility
   OM4 multimode supports high-speed short-reach transmission; OS2 single-mode delivers long-distance low-loss performance.
5. Bend-Insensitive and Rugged Design
   Engineered with BIF and G.657.A1 fibers to maintain signal integrity under tight bends and frequent handling.
6. Fire-Safe and Lightweight Construction
   Plenum (OFNP) jacket meets stringent safety codes while maintaining flexibility and easy routing.
7. Factory-Terminated Reliability
   Every assembly undergoes 100 % IL/RL testing and inspection, ensuring stable field deployment.

FAQ

1. What is an MMC connector?
   The MMC is a Very Small Form Factor (VSFF) connector from US Conec that provides 3× the port density of traditional MPO interfaces.
2. What’s the difference between OM4 and OS2 versions?
   OM4 is a multimode fiber for short-reach, high-bandwidth links, while OS2 is a single-mode fiber for long-distance transmission.
3. Is this compatible with MTP/MPO connectors?
   Not directly. MMC and MPO use different interfaces, but hybrid MMC-to-MTP cables are available for migration applications.
4. What is the typical insertion and return loss?
   Insertion loss ≤ 0.35 dB (max) and return loss ≥ 40–60 dB depending on fiber type and polish.
5. Can I order custom lengths or colors?
   Yes. Lengths, colors (Magenta, Yellow, Aqua etc.), and labeling can be customized to your project requirements.
6. What jacket rating does it use?
   Plenum (OFNP), compliant with building fire safety standards for indoor air-handling spaces.
7. Does HOLIGHT offer OEM/ODM service?
   Yes. We provide OEM/ODM options including logo printing, private labeling, and special packaging.
8. How is each jumper tested before shipment?
   Each assembly is individually tested for insertion loss, return loss, and visual end-face inspection to ensure consistent performance.
