Connecting Standard and High-Performance Fiber: The “Blue to Green” Solution
In today’s evolving fiber optic networks, you often encounter situations where you need to connect equipment using different connector polish types. Standard devices might use SC/UPC (Ultra Physical Contact) connectors, recognizable by their blue color, while newer or more sensitive equipment, especially in CATV or telecom, might utilize SC/APC (Angled Physical Contact) connectors, identified by their green color. The Syrotech SC/UPC to SC/APC Single Mode Duplex Fiber Optic Patch Cord is specifically designed to create a reliable link between these two distinct interface types.
Understanding the “Blue to Green” Connection
-
SC/UPC (Blue): This is a widely deployed standard connector offering good performance with low insertion loss and decent return loss (typically >50dB). The “Ultra Physical Contact” polish ensures good fiber core alignment. It’s common on many OLTs, switches, and patch panels.
-
SC/APC (Green): This connector is engineered for superior performance in applications sensitive to signal reflections. The fiber end-face is polished at an 8-degree angle (Angled Physical Contact). This angle directs reflected light away from the fiber core, resulting in extremely high return loss (typically >60dB). This is critical for analog signals and high-speed digital systems.
This patch cord features one blue SC/UPC duplex connector pair on one end and one green SC/APC duplex connector pair on the other, housed within a standard yellow single mode duplex cable jacket. The duplex configuration provides separate fibers for transmitting and receiving data.
Why This Hybrid Cable is Essential
Using a patch cord with mismatched polish types (like connecting a UPC directly to an APC port) can cause significant performance issues, including high loss and damaging reflections. This specialized SC/UPC to SC/APC cable ensures:
-
Proper Interface Matching: Allows seamless connection between devices designed for different polish types.
-
Optimal Performance: Leverages the high return loss benefits of the APC connector on the equipment side that requires it, while maintaining compatibility with the standard UPC port on the other side.
-
Signal Integrity: Minimizes signal degradation and interference caused by reflections, crucial in sensitive networks.
Engineered for Reliability and Performance
Syrotech patch cords are manufactured to high standards:
-
Quality Fiber: Uses premium G.652.D compliant 9/125µm single mode fiber, suitable for high-bandwidth applications.
-
Precision Connectors: High-quality SC/UPC and SC/APC connectors with ceramic ferrules ensure accurate alignment, low insertion loss (typically <0.3dB), and consistent performance.
-
Robust Construction: The duplex cable (often 2.0mm or 3.0mm diameter zipcord) provides protection for the individual fibers, while the standard yellow jacket clearly identifies it as single mode.
-
Factory Tested: Each cable is tested to meet optical performance standards, ensuring reliable operation.
Common Use Cases and Scenarios
This patch cord is invaluable when integrating equipment:
-
Telecom Central Offices: Connecting distribution frames (often UPC) to transmission equipment specifying APC interfaces.
-
CATV Networks: Linking headend equipment (often APC) to distribution hubs or nodes that may use UPC.
-
FTTH Deployments: Patching between OLT ports (which can be UPC or APC) and distribution panels or ONTs requiring a specific polish type.
-
Upgrading Networks: Integrating newer APC-based equipment into existing UPC infrastructure without compromising performance at the critical interface.
-
Testing Environments: Providing flexible connectivity options in labs testing devices with different interface requirements.
