Optický jumper kábel ROLINE OM4 50/125µm LC/ST 3m

The ROLINE Fibre Optic Jumper Cable OM4 50/125µm LC/ST 3m is a laser-optimized multimode patch cable designed for high-speed, full-duplex links. With a 50 µm core and OM4 specification, this 3-meter jumper supports existing 1 and 10 Gbit/s networks and provides extended reach for future 40 and 100 Gbit/s systems. The cable features one LC and one ST connector and comes in the characteristic purple OM4 jacket for easy identification in installations.

Advantages

OM4 fiber offers increased laser bandwidth (approximately 4700 MHz·km), enabling longer reach at 10 Gbit/s—up to around 550 meters—and improved performance for 40 Gbit/s and 100 Gbit/s links compared with lower-grade multimode fibers. The 50/125µm core maintains compatibility with common Ethernet, Fibre Channel and OIF equipment while remaining suitable for lower data rates such as 100 Mbit/s and 1 Gbit/s. The pre-terminated LC to ST jumper simplifies deployment in data centers, campus backbones and building cabling.

Suitable for

• 10 Gbit/s Ethernet links up to ~550 m
• 40 Gbit/s and 100 Gbit/s short-reach applications in data centers
• Connections between switches and patch panels using LC and ST ports
• High-performance computing interconnects and backbone segments

Key specifications

• Fiber type: OM4 multimode, 50/125 µm
• Bandwidth (laser): ~4700 MHz·km
• Connectors: LC to ST (one each)
• Length: 3 m
• Color: Purple (OM4 identification)
• Applications: Ethernet, Fibre Channel, OIF

How to use

Inspect connector endfaces for cleanliness before installation and clean if necessary. Insert the LC connector into the LC port and the ST connector into the ST port, ensuring secure mating and proper orientation. Route the cable following standard bend-radius and cable-management guidelines to avoid stress on the fiber. Confirm link status and perform optical testing or certification as required for your network standards.

Recommendations

The OM4 jumper is recommended where higher bandwidth and extended reach at 10 Gbit/s or above are required, such as data center aggregation layers and medium-length campus backbones; for short-reach connections in densely populated racks, verify connector type compatibility and maintain proper cleaning and handling procedures.
