## Summary description

ROLINE 21.15.8655 is a 7 m OM4 fibre optic cable with LC–LC connectors designed for high-speed full-duplex data transmission. It features 50 µm core diameter multimode fibre and LC connectors on both ends for easy patching in InfiniBand and fibre-optic network links. Suitable for data centres, server racks and storage networking where short-range multimode links are required.

## Long description

ROLINE 21.15.8655 is a 7 m OM4 multimode fibre optic patch cable with LC–LC uniboot connectors, designed for full-duplex high-speed links in data centres, server racks and storage networking. The cable uses 50 µm core multimode fibre optimized for short- to medium-range multimode connections. The compact uniboot LC design reduces connector density and simplifies routing while allowing easy polarity changes without special tools. The jacket is low-smoke, zero-halogen (LSZH) material suitable for indoor installations where reduced smoke and halogen emissions are required.
Advantages
This OM4 fibre offers high modal bandwidth and low insertion loss for reliable transmission of 10 Gbit/s Ethernet, Fibre Channel and OIF applications up to typical multimode distances. The uniboot LC connector provides a compact duplex solution that saves space in high-density panels and simplifies cable management. The LSZH jacket adds improved safety in confined indoor environments and the violet jacket color helps with quick visual identification of OM4 multimode runs.
Suitable for
Data centre interconnects and top-of-rack patching
Server and storage area network (SAN) links
High-density patch panels and fibre trays
Campus backbone segments and equipment rooms for short- to medium-range multimode runs
Key specifications
Fibre type: Multimode 50/125 µm, OM4
Connector type: LC to LC uniboot, duplex full-duplex operation
Length: 7 m
Modal bandwidth: 4700 MHz·km
Data rate support: up to 10 Gbit/s (and compatible with Fibre Channel and OIF applications)
Jacket material: Low smoke, zero halogen (LSZH)
Cable color: Violet (OM4 identification)
How to use
Route the cable between LC adapter ports in patch panels, switches or transceivers ensuring minimal bend radius is respected to avoid signal attenuation. Insert LC connectors into compatible LC duplex adapters until they click into place. If polarity needs to be changed, use the uniboot’s built-in polarity flip feature or re-route the duplex legs as required; no special tools are necessary. Verify link status and optical power levels with appropriate test equipment after installation.
Usage recommendations
For reliable performance, avoid tight bends and sharp kinks, keep connector end-faces clean and protected with dust caps until installation, and follow standard multimode fibre handling procedures. Use OM4 fibre for short- to medium-range high-bandwidth applications and ensure patch panels and transceivers are LC-compatible.
