SC to ST Single Mode Fiber Patch Cable - Duplex
High-performance single-mode fiber optic patch cable bridging standard and legacy equipment with SC/UPC connectors on one end and ST/UPC connectors on the other. The SC push-pull connector (Subscriber/Standard Connector) is the industry standard for FTTH applications, GBIC modules, and telecom/datacom networks. In contrast, the ST bayonet-style connector (Straight Tip) provides secure twist-on/twist-off installation for legacy networking equipment. Perfect for connecting widely-deployed SC infrastructure to older ST equipment.
Key Features
- High-speed single-mode transmission for long-distance, high-bandwidth applications
- UPC polish on both ends - ultra-flat ferrule surface maximizes signal transmission
- Dual connector design - standard SC for versatile connectivity, bayonet ST for legacy systems
- SC push-pull connector with 2.5mm ferrule for reliable, industry-standard connections
- ST bayonet connector with simple twist-on/twist-off mechanism for secure installation
- Low insertion loss - ≤0.15 dB typical for optimal performance
- Tool-free installation on both ends - push-pull SC and twist-lock ST
- FTTH ready - SC connector is the standard for fiber to the home applications
- GBIC compatible - SC connector works with most GBIC modules
- UL Listed in both Canada and the US (Intertek 4009521)
- RoHS compliant for environmental safety

Applications
Ideal for FTTH (fiber to the home) deployments, connecting SC-equipped GBIC modules to ST legacy equipment, enterprise network upgrades, telecommunications infrastructure, datacom and telecom networks, network migrations, and any application requiring connectivity between standard SC ports and traditional ST connections.
Why SC to ST?
This hybrid cable is essential for maintaining compatibility between modern FTTH and telecom infrastructure (which predominantly uses SC connectors) and legacy equipment with ST ports, enabling seamless integration during network upgrades and phased infrastructure modernization without complete system replacement.
