LC to SC Patch Cord Single Mode Duplex UPC | OS2 Fiber Jumper Cable

Overview

Ensure robust and high-speed data transmission across your network infrastructure with our premium LC to SC Patch Cord Single Mode Duplex. Designed for telecommunications providers, data centers, and enterprise LANs, this fiber optic assembly serves as a critical bridge between equipment with differing connector interfaces. Specifically, it connects high-density LC SFP modules to legacy SC patch panels or switches without requiring complex adapters.

Engineered for minimal signal degradation, this fiber optic patch cable utilizes high-grade G.657.A1 or G.652.D optical fiber, ensuring strict adherence to industry standards. Whether you are upgrading an existing backbone or deploying new fiber-to-the-home (FTTH) connections, the LC-SC hybrid jumper delivers consistent performance. Its reliable construction minimizes back reflection, making it an ideal choice for sensitive, high-bandwidth applications where data integrity is paramount.

Key Features

• Precision Connectors: Factory-terminated LC/UPC to SC/UPC connectors utilize zirconia ceramic ferrules for optimal alignment and low optical loss.
• High-Quality Fiber Glass: Built with 9/125μm Single Mode OS2 fiber, fully compatible with standard Ethernet and Fibre Channel transmission rates.
• Durable Jacket: Features a flame-retardant Low Smoke Zero Halogen (LSZH) jacket, ensuring safety and compliance in enclosed building environments.
• Strict Testing Standards: Every SC to LC patch cord undergoes 100% optical testing for insertion loss and return loss before shipment.
• Robust Design: The duplex zip-cord construction allows for easy polarity management and organized cable routing in high-density racks.

Applications

The versatility of the LC to SC single mode duplex cable makes it indispensable in modern networking environments. It is frequently deployed in Telecommunication Networks for long-haul data transmission and in Local Area Networks (LANs) to connect switches to distribution frames. Additionally, network engineers rely on these cables for CATV networks and fiber test equipment setups (OTDR launch cables).

In Data Centers, where space is at a premium, the small form factor of the LC connector combined with the ruggedness of the SC connector allows for flexible equipment interconnection. This fiber jumper cable effectively bridges the gap between newer 10G/40G hardware and established fiber infrastructure, facilitating seamless network upgrades.

Specifications

Advantages

Choosing the right LC to SC fiber patch cord significantly impacts network reliability. Our cables are manufactured using advanced polishing techniques, resulting in a physical contact surface that dramatically reduces light reflection. Consequently, this ensures that your network maintains high throughput and low error rates, even over longer distances typical of single mode fiber deployments.

Furthermore, the transition from SC to LC interfaces often poses a compatibility challenge during hardware refreshes. By utilizing a high-quality hybrid patch lead, you eliminate the need for additional attenuators or converters that could introduce failure points. The robust strain relief boots on both ends protect the delicate fiber core from bending and tension, ensuring a long service life and reducing long-term maintenance costs for IT departments.

FAQ (Technical & Product Questions)

1. What is the difference between LC and SC connectors?

The main difference lies in the size and locking mechanism. The SC connector (Subscriber Connector) is a push-pull connector with a 2.5mm ferrule, often used in datacom and older gear. The LC connector (Lucent Connector) is smaller (1.25mm ferrule) with a latch mechanism similar to an RJ45, designed for high-density switching applications. An LC to SC patch cord connects these two distinct types.

2. Can I use this Single Mode cable for Multimode applications?

No, you should not mix fiber types. This is a Single Mode OS2 cable (Yellow jacket, 9/125μm core) designed for long-distance transmission. Multimode equipment (typically using Orange or Aqua OM3/OM4 cables) uses a much larger core (50μm or 62.5μm). Connecting single mode cabling to multimode ports will result in massive signal loss.

3. What does UPC stand for in LC/UPC and SC/UPC?

UPC stands for “Ultra Physical Contact.” It refers to the polish style of the fiber end-face. UPC connectors are polished to a finer finish than standard PC connectors, providing a better Return Loss (typically ≥ 50dB). This makes the SC-LC duplex fiber jumper suitable for digital TV, telephony, and data systems.

4. Is the LSZH jacket necessary for my installation?

Yes, in many cases. LSZH (Low Smoke Zero Halogen) jackets are safer than standard PVC. In the event of a fire, LSZH cables emit very little smoke and no toxic halogen gases. Many building codes and data centers require LSZH fiber optic cables to ensure personnel safety and protect sensitive electronic equipment from corrosion.

5. How do I clean the connectors on this patch cord?

To maintain low insertion loss, always clean the ferrule end-faces before mating. You can use a specialized lint-free wipe with isopropyl alcohol or a one-click cleaning pen designed for 1.25mm (LC) and 2.5mm (SC) ferrules. Dust is the #1 cause of fiber optic signal failure, so keep the protective dust caps on when the cable is not in use.
