Product Profile
- The 24F AR Coated MPO MTP Test Cable is a non-contact reference cable developed for high-frequency MPO/MTP® testing. Its AR-coated, recessed fiber end-face maintains a controlled air gap, helping reduce back reflection, prevent end-face wear, and improve measurement repeatability during repeated mating.
- Designed for testing 400G, 800G, and 1.6T optical modules and MPO/MTP® assemblies, it helps build a more stable test link and minimize performance fluctuations caused by contamination or mechanical contact. MNC-MNC and MNC-MPO configurations are available for different test setups.
Key Technology Explanation
At the silica-to-air interfaces created by the non-contact geometry, the AR coating helps reduce Fresnel reflection and limit multiple-reflection effects that may contribute to Fabry-Perot interference. This helps control insertion-loss and return-loss behavior at the specified operating wavelength.
Each fiber end-face is recessed below the ferrule surface by approximately 0.6-6 μm. After mating, an air gap of approximately 1.2 μm remains between the opposing fiber end-faces. Because the fiber surfaces remain separated, the interface avoids direct end-face friction and reduces sensitivity to contamination and uneven contact across the 24-fiber array.

Product Features
Modified Non-Contact End-Face Design
The recessed fiber end-face maintains a controlled air gap between mating fibers, preventing direct fiber contact and reducing scratches and wear during repeated mating.
AR-Coated Optical Interface
The AR coating suppresses back reflection at the fiber-air interface, helping limit Fabry-Perot interference and maintain stable insertion-loss and return-loss measurements during high-frequency testing.
Precision MPO/MTP® Connector
The 24F MNC connector follows the standard MPO/MTP® form factor for precise fiber alignment and compatibility with existing adapters, optical modules, and test equipment. Male, female, APC, and UPC configurations are available.
Durable Outer Jacket
Available with LSZH, OFNR, or OFNP outer jackets, the cable provides mechanical protection, flexibility, and flame-retardant performance for different indoor test environments.
MNC™ vs. Traditional MPO / MTP
| Item | Traditional MPO / MTP | MNC™ Connector |
|---|---|---|
| Connection | Physical contact between most fibers |
Non-contact; air gap maintained between fibers |
| Optical Reflection | Multiple reflections forming Fabry-Perot cavity |
AR coating suppresses reflection; stable signal |
| End-Face Wear Risk | High | Extremely low |
| Contamination Sensitivity | High | Low |
| Required Mating Pressure | High | Low; small pressure is sufficient |
| High-Fiber-Count Performance | Poor; instability increases with fiber count | Excellent; stably supports high fiber counts |
| Service Life | Baseline |
Approximately 10× MPO/MTP; more than 500 mating cycles |
| Impact on DUT | Possible end-face damage | No damage; protects valuable devices under test |
