Fibre optic cable VALUE 21.99.8754 OM4 LC–LC, 50 µm multimode, full duplex, 7 m, violet

VALUE 21.99.8754 is a 7 m OM4 multimode fibre optic cable with LC connectors on both ends (LC–LC). It features a 50/125 µm core/cladding multimode fiber in a violet PVC jacket and supports full-duplex transmission for high-speed short-range links in data centers, SANs and network interconnects. OM4 fiber provides extended reach and high laser bandwidth suitable for current 1 and 10 Gbit/s links and future 40 and 100 Gbit/s systems.

Advantages

OM4 multimode fiber offers a high laser bandwidth (approximately 4700 MHz·km) that exceeds standard requirements for 10 Gbit/s over 300 m and allows extended 10 Gbit/s reach up to about 550 m in suitable installations. The LC–LC connectorization provides compact duplex connections commonly used in networking equipment, while the violet jacket simplifies port and cable identification. The 7 m length is convenient for rack-to-rack or cabinet-to-cabinet links inside data centers.

Suitable for

• Short-range data center links and top-of-rack connections
• Storage area network (SAN) interconnects
• Cabling between switches and patch panels within racks or cabinets
• Campus backbone segments with medium reach requirements

When it may not be suitable

This 7 m OM4 LC–LC cable is not intended for long-haul or outdoor runs; its PVC jacket is designed for indoor use only. It may be unnecessary for very short patching within a single rack where shorter cables would offer neater cable management.

Key specifications

• Fiber type: multimode 50/125 µm (OM4)
• Connector type: LC to LC, duplex
• Length: 7 m
• Jacket material: PVC (polyvinyl chloride)
• Color: violet
• Transmission: full-duplex
• Typical laser bandwidth: ~4700 MHz·km (OM4)

How to use

Install the LC–LC cable by aligning and inserting the LC connectors into the corresponding LC ports on network devices or patch panels until they click into place. Route the cable to avoid sharp bends and mechanical strain; maintain the minimum bend radius recommended for multimode fibers. Use cable management panels or ties to secure runs and keep duplex pairs together for correct polarity.

What to consider before purchase

• Required length — ensure 7 m fits your rack-to-rack or equipment spacing
• Connector compatibility — confirm devices use LC duplex ports
• Indoor vs. outdoor use — PVC jacket is for indoor installations
• Network speed and reach — OM4 supports 1/10 Gbit/s and future 40/100 Gbit/s short-reach links

Usage recommendations

For reliable performance, avoid bending beyond the fiber's rated minimum bend radius, keep connectors clean using appropriate cleaning tools, and label the violet cable for quick identification in patch panels and racks.
