## Summary description

## Long description

ROLINE 21.15.8657 InfiniBand/fibre optic cable 15 m LC LC/LC Violet is a uniboot OM4 multimode patch cord designed for high-density data centre and network cabling. The cable integrates two fibers in a single, compact uniboot jacket with LC connectors on both ends, offering full-duplex transmission and low insertion loss for demanding applications up to 10 Gbit/s and beyond at extended distances. The LSZH jacket reduces smoke and hazardous emissions in case of fire, while the violet colour provides easy visual identification in structured cabling environments.
Advantages
This OM4 LC‑LC uniboot patch cord offers high modal bandwidth and low attenuation, supporting extended reach for 10 Gbit/s Ethernet, Fibre Channel and other high‑speed links. The uniboot design reduces cable bulk and simplifies routing in high‑density panels and transceiver arrays. Fibre polarity can be changed quickly without special tools, reducing installation time and maintenance effort. The jacket and components are manufactured to ROLINE quality standards for consistent mechanical and optical performance.
Suitable for
 High‑density patch panels and rack installations
 Data centres and server rooms requiring OM4 performance
 10 Gbit/s Ethernet and Fibre Channel links up to medium/long backbone distances
 Connections between switches, transceivers and optical patch panels
Key specifications
 Cable length: 15 m
 Connector type: LC to LC (uniboot)
 Fibre type: Multimode OM4, 50/125 µm core/cladding
 Modal bandwidth: 4700 MHz·km
 Transmission: Full duplex
 Rated data rate: supports 10 Gbit/s and relevant high‑speed protocols
 Jacket material: Low smoke, fire retardant, zero halogen (LSFRZH/LSOH)
 Colour: Violet (for visual identification)
How to use
Route the uniboot cable through cable management and secure it to avoid tight bends; maintain the manufacturer recommended minimum bend radius for multimode fibres. Insert the LC connectors into the corresponding LC adapters or transceiver ports until they click. If polarity change is required, use the uniboot flip method described by the installer guidelines—no special tools are needed. Test the link with appropriate fibre testers to verify insertion loss and continuity before placing the connection into production.
Usage recommendations
Store and handle the OM4 cable in a clean environment, avoid contamination of connector endfaces, and inspect/clean connectors before mating. Use designated cable management and strain relief in high‑density panels to preserve optical performance and reduce the risk of damage during installation or moves.
