Fibre Optic Jumper Cable ROLINE OM4 50/125µm LC/ST 10 m

The ROLINE Fibre Optic Jumper Cable OM4 50/125µm LC/ST, 10 m, is a duplex patch cable designed for high-speed network connections. It uses laser-optimized OM4 multimode fiber with a 50 µm core to support current 1 and 10 Gbit/s links and future 40 and 100 Gbit/s systems. The cable comes with LC and ST connectors and a purple jacket for easy identification in installations.

Advantages

OM4 fiber provides extended bandwidth (laser bandwidth ~4700 MHz·km) and supports longer reaches at higher data rates than lower-grade multimode fibers. The duplex 50/125 µm construction and quality connector assembly yield low insertion loss and low back reflection, making the jumper suitable for data centers, campus backbones and high-performance computing environments. The 10 m length and LC/ST connector combination offer flexibility for a range of patching needs.

Suitable for

• 10 Gbit/s Ethernet links up to 550 m in building backbones
• 40/100 Gbit/s short-reach links in data centers and HPC
• Ethernet, Fibre Channel and OIF multimode applications
• General duplex optical patching and equipment interconnects

How to use

Route the duplex fibre jumper between the LC and ST ports of the network devices or patch panels, observing correct polarity for transmit and receive channels. Avoid tight bends and secure the cable to prevent stress on connectors. When inserting or removing connectors, hold the connector body rather than pulling the fiber jacket to reduce strain and risk of damage.

Recommendations

For reliable performance, keep bend radius above the manufacturer’s minimum, verify connector cleanliness before mating, and use OM4 jumpers where higher bandwidth or extended 10 Gbit/s reach is required. Store and handle the cable in a dry, dust-free environment to maintain low insertion loss and return loss.
