Fibre optic cable ROLINE 21.15.8650 OM4 LC–LC 0.5 m, 50 µm, duplex, violet

ROLINE 21.15.8650 is a 0.5 m OM4 fiber optic patch cable with LC to LC uniboot connectors, 50 µm multimode cores and full duplex transmission. The violet jacket and compact uniboot design make this cable suitable for high-density installations in data centers, SANs, switches and InfiniBand environments where OM4 multimode fiber is specified. The cable uses low-smoke, zero-halogen jacket material and delivers high modal bandwidth for short- to medium-reach high-speed links.

Advantages

The uniboot LC–LC design combines two fibers in a single compact connector body to save port space in racks and patch panels. OM4 multimode fiber provides increased modal bandwidth, enabling reliable 10 Gbit/s and higher-speed links over short distances. The LSZH jacket reduces smoke and toxic gas emission risk in case of fire, and the cable allows easy polarity changes without special tools. ROLINE construction and component selection ensure consistent insertion loss and mechanical durability for demanding cabling environments.

Suitable for

• High-density patch panels and top-of-rack cabling
• Short-reach data center links (10 Gbit/s and compatible higher-speed applications)
• Storage area networks (Fibre Channel)
• InfiniBand clusters and high-performance computing interconnects
• Campus backbone segments and switch-to-switch connections within supported distances

Key specifications

• Fiber type: Multimode 50/125 µm, OM4
• Connector type: LC–LC uniboot, duplex functionality
• Length: 0.5 m
• Transmission: Full duplex
• Bandwidth (modal): 4700 MHz·km
• Supported data rates: up to 10 Gbit/s (application dependent)
• Jacket material: Low smoke, zero halogen (LSZH/LSFRZH)
• Color: Violet

How to use

Route the 0.5 m cable between LC ports on compatible transceivers, switches or patch panels, aligning each LC connector to the corresponding port. The uniboot assembly occupies less space than separate duplex connectors; ensure correct polarity before final insertion. For polarity reversal, follow the connector’s simple mechanical procedure—no special tools required. Handle connectors with dust caps until installation and avoid excessive bending of the fiber to maintain optimal signal performance.

Usage recommendations

Use this OM4 LC–LC uniboot patch cord for short-reach, high-density applications where high modal bandwidth and compact connector footprint are required. Confirm transceiver and channel specifications (distance and data rate) to ensure OM4 multimode is suitable for your link, and maintain proper cable management to avoid bend radii below manufacturer guidelines.
