Description
💎 Engineered for Extreme Stability
The inclusion of a metal stop transforms the internal load path of the connector, offering distinct advantages over all-plastic alternatives:
-
Metallic Structural Anchor: The Zinc Alloy stop provides a non-deformable base for the internal spring, ensuring constant 8° angled physical contact (APC) even under high axial tension.
-
High-Tension Crimp Interface: Designed to withstand a pull strength of ≥100N, the metal internal body allows for a more aggressive crimp on the Aramid yarn (Kevlar) of 2.0mm and 3.0mm jackets.
-
Anti-Pistoning Design: The rigid metal stop prevents the ferrule from retracting during temperature cycles, maintaining a stable Return Loss of ≥60dB.
-
Enhanced Heat Dissipation: Metallic components help stabilize the internal core temperature in high-power laser applications (like CATV), preventing thermal degradation of the fiber epoxy.
-
Carrier-Grade Durability: Tested for over 1,000 mating cycles, the zinc alloy components ensure the latching mechanism remains tight and the ferrule alignment remains precise for the lifespan of the network.

💡 Expert Sourcing & Installation FAQ
Q: When is it mandatory to use the Zinc Alloy Stop instead of an All-Plastic model?
A: You should specify the Zinc Alloy Stop for any installation involving 3.0mm cables in vertical rises, long-span trays, or industrial settings. The metal stop prevents the weight of the heavy cable from pulling the fiber core out of alignment, which is a common failure point in all-plastic connectors.
Q: Does this model support both UPC and APC polishing?
A: While the zinc-stop architecture is available for both, this specific Green-Housed model is dedicated to APC (Angled Physical Contact). The internal metal stop is critical for APC because it ensures the 8-degree angle remains perfectly oriented against the mating ferrule.
Q: Is the assembly process different for metal-stop connectors?
A: The assembly logic is identical to standard SC connectors, but the metal stop provides a more tactile “bottom-out” during the crimping process. This gives technicians better feedback, leading to higher first-pass yields in factory production environments.
Q: What comes in a standard bulk kit?
A: Every kit is a complete 5-piece assembly: The SC Green Housing, Zirconia Ferrule with Zinc Alloy Stop, High-Tension Spring, Metal Crimp Sleeve, and the Universal 2.0/3.0mm Boot.
