SC/APC Duplex Fiber Jumpers & Single Mode and Patch Cables, Patch Lead and Fiber Flylead

HHD supplies  high-performance SC/APC fiber optic jumpers, also known as fiber jumper cables, fiber patch leads, fiber flyleads, fiber optic patch cords or fiber patch cables in different markets. This SC/APC to SC/APC duplex 3.0mm APC single mode jumper is designed for FTTH, ODF, terminal boxes, CATV, GPON and indoor optical network connections. Our optical fiber jumpers is available in both armored and unarmored structures, with OS2 G.657.A2 bend-insensitive fiber for compact routing and stable optical performance.

Key Features and Benefits

Armored and Unarmored Options

For protected indoor routing, the armored version uses a  SUS204/304 spiral stainless steel armor structure under the outer jacket to improve resistance against bending, crushing, accidental stepping and rodent damage. For standard cabinet, ODF and equipment connections, the unarmored version provides a lighter and more flexible option for daily patching work.

G.657.A2 Bend-Insensitive Singlemode Fiber

The G.657.A2 fiber option is suitable for tight routing areas such as FTTH boxes, wall-mounted enclosures, ODF trays and high-density patch panels. It helps reduce bend-related signal loss in compact spaces. When used with existing G.652.D singlemode networks, we recommend confirming splice loss and link loss budget based on the actual project requirements.

SC/APC Connectors for Low Reflection Links

The green SC/APC connectors are designed for applications that require low back reflection, such as GPON, CATV, FTTH and WDM optical links. Each cable can be supplied with factory-polished ceramic ferrules and tested for insertion loss and return loss before shipment.
Insertion Loss: ≤ 0.3 dB, typical < 0.2 dB
Return Loss: ≥ 60 dB for APC polish
Connector Type: SC/APC to SC/APC duplex
Fiber Type: OS2 9/125 singlemode, G.652.D / G.657.A1 / G.657.A2 options

PVC or LSZH Jacket Options

PVC and LSZH jacket materials are available for different installation requirements. LSZH is commonly selected for indoor cabling areas where low smoke and halogen-free materials are preferred, while PVC is often used for standard equipment rooms, cabinets and patching environments.

Frequently Asked Questions

What is the difference between a duplex fiber patch cord and a simplex fiber patch cord?

SC/APC duplex fiber optic jumper cable, patch lead and fiber flylead for FTTH, ODF, terminal boxes, CATV and GPON links. 2-core OS2 singlemode cable with G.652.D, G.657.A1 and G.657.A2 options.

Are fiber jumper cables, patch leads and fiber flyleads the same product?

Yes. These terms are often used to describe the same type of connectorized fiber cable. “Fiber patch cord” and “fiber jumper cable” are widely used in North America and global B2B markets, while “patch lead” and “fiber flylead” are more common in the UK, Europe, Australia and telecom engineering applications.

Why choose SC/APC connectors for singlemode duplex jumpers/fiber flyleads/fiber leads?

SC/APC connectors use an 8-degree angled polish to help reduce back reflection at the connection point. This makes them suitable for singlemode networks where low return loss is important, including FTTH, GPON, CATV, ODF, terminal box and other optical equipment connections.

Where are SC/APC duplex fiber jumpers commonly used?

SC/APC duplex fiber optic jumper cables are commonly used in FTTH networks, ODF patching, fiber terminal boxes, telecom equipment rooms, CATV systems, GPON links, security systems, broadcasting equipment and selected long-distance singlemode optical links.
