JUMPER, SC-SC, DUPLEX, SM, 1M

SC-SC Duplex Single Mode Fiber Jumper Cable – 1 Meter

The Jumper, SC-SC, Duplex, SM, 1M is a high performance fiber optic patch cord designed for single mode network applications requiring long distance transmission and high bandwidth. With SC connectors on both ends, a duplex (two fiber) design, and a 1 meter (approximately 3.3 feet) length, this cable is ideal for connecting network switches, routers, fiber patch panels, and other network accessories in data centers, telecom central offices, campus networks, and enterprise environments. Single mode fiber is the standard for distances beyond a few hundred meters and for high speed protocols such as 10G, 40G, and 100G Ethernet. It is an essential cable management accessory for building reliable, high performance backbone connections that support everything from data center core switching to specialized applications involving headsets, phones, and other office accessories that depend on fast, low latency network infrastructure.

SC Connectors and Duplex Design

SC (Subscriber Connector or Standard Connector) features a push pull latching mechanism that provides a secure, low loss connection with excellent repeatability. SC connectors are widely used in data centers, telecom rooms, and enterprise networks due to their durability, low cost, and ease of use. The ceramic ferrule ensures precise fiber alignment for minimal insertion loss and back reflection, which is especially critical for single mode applications where signal integrity is paramount. The duplex design combines two fibers (one transmit, one receive) in a single zip cord or round jacket, simplifying cable runs and maintaining proper polarity. This two fiber configuration is essential for full duplex communication where data flows simultaneously in both directions, making it the standard choice for equipment patching and backbone links in professional network installations.

Single Mode Performance and 1 Meter Length

This cable uses 9/125µm single mode fiber (core/cladding diameter), which is the global standard for long distance and high speed networking. Unlike multimode fiber, single mode fiber transmits only one mode of light, eliminating modal dispersion and allowing signals to travel many kilometers without significant degradation. Typical performance includes support for Gigabit Ethernet up to 5 kilometers, 10 Gigabit Ethernet up to 10 kilometers or more, and 40G/100G Ethernet over extended distances depending on the optics used. The 1 meter length is perfect for very short connections within a single rack, between adjacent devices in a cabinet, or from a patch panel to equipment directly above or below. Typical applications include connecting single mode backbone fibers to distribution switches, patching between fiber panels in a main distribution frame (MDF), and linking wavelength division multiplexing (WDM) equipment to network switches.

Durable Construction and Easy Installation

The cable features a PVC (OFNR) jacket rated for indoor use, including riser applications between floors. It is flexible enough for routing through cable management trays, raceways, or under floors without kinking. The duplex design allows for easy polarity tracking, with the two fibers typically marked by A and B indicators or different colored strain relief boots or connectors. Installation is straightforward: insert SC connectors into compatible ports and push until they click into place, ensure the transmit fiber connects to the receive port on each device, and secure the cable with hook and loop straps without over tightening. In data center environments with headsets, phones, and other office accessories nearby, single mode fiber jumpers provide completely interference free connectivity that is immune to electromagnetic noise from power cables, cooling systems, or other office equipment.

Why Choose SC-SC Single Mode Jumpers

SC connectors remain extremely common in both legacy and modern installations due to their proven reliability, low cost, and intuitive operation. The push pull mechanism allows for one handed operation even in tight spaces, and the square shape enables high density mounting on patch panels. Single mode fiber is the right choice for any link longer than a few hundred meters or for any link requiring speeds of 10 Gigabit or higher. While multimode fiber is often sufficient within a single data center, single mode provides future proofing and consistency across campus and metropolitan area networks. This specific jumper is ideal for connecting single mode equipment in the same rack or adjacent racks, such as connecting a transceiver to a patch panel or linking two pieces of active equipment directly.

Best Practices for Installation and Use

To achieve optimal performance from your single mode fiber jumper, keep connectors scrupulously clean by using a fiber optic cleaning pen or lint free wipes with isopropyl alcohol before each connection. Single mode connectors are more sensitive to contamination than multimode connectors because the smaller core size means even microscopic dust particles can cause significant signal loss or back reflection. Avoid tight bends, as the minimum bend radius for single mode fiber is typically 10 to 15 times the cable diameter, and sharp bends will increase signal loss and can permanently damage the fiber. Use appropriate cable management hardware such as horizontal or vertical cable managers, and never let fiber jumpers hang by their own weight. Protect connectors with dust caps when not in use to prevent contamination, and label both ends of each jumper with color coded labels to identify cable runs and maintain proper polarity.

Complementary Products for a Complete Single Mode Setup

To complete your single mode fiber installation, pair this SC-SC jumper with SC fiber adapters (couplers), single mode fiber patch panels, cable management rings, and precision cleaning accessories. For longer runs, consider bulk single mode fiber cable with field installable connectors or factory terminated assemblies.
