Fibre Optic Jumper Cable ROLINE LC/ST OM4 50/125µm 0.5m

The ROLINE Fibre Optic Jumper Cable LC/ST OM4 50/125µm 0.5m is a short patch cable designed for high-performance networks. It uses laser-optimized OM4 multimode fiber with a 50 µm core and LC and ST connectors, providing full-duplex optical links for switches, servers and active equipment in data centres and campus backbones.

Advantages

OM4 fiber offers extended laser bandwidth and improved performance at 10 Gbit/s, 40 Gbit/s and 100 Gbit/s compared with lower-grade multimode fibers. This 0.5 m jumper provides low-loss connections for short-reach applications, is colour-coded purple to indicate OM4 compatibility, and combines LC and ST connector types for flexible equipment compatibility.

Suitable for

• Short-reach connections in data centres (server to switch)
• High-performance computing interconnects
• Building and campus backbone links requiring OM4 performance
• Environments requiring LC to ST connectivity

Key specifications

• Fiber type: OM4 multimode, 50/125 µm
• Connectors: LC to ST (one end LC, other end ST)
• Length: 0.5 m
• Duplex: full duplex
• Colour: purple (OM4 identification)
• Manufacturer: ROLINE, MPN: 21.15.8770, EAN: 7611990196401

How to use

Insert the LC connector into the LC port and the ST connector into the ST port on the respective devices, taking care to align keys and ferrules correctly. Use this 0.5 m jumper for short-distance connections where OM4 performance is required; avoid sharp bends and keep connectors clean to minimise insertion loss. Ensure both ends are securely latched or locked according to the equipment connector type before powering the network.

Recommendations

For optimal performance at higher data rates (10 Gbit/s and above), use OM4-compliant transceivers and maintain connector cleanliness. OM4 excels at extended 10 Gbit/s reaches and short-reach data centre links; for lower speeds (100 Mbit/s, 1 Gbit/s) performance is similar to OM2/OM3.
