Fibre Optic Cable ShiverPeaks BS77907/4 20m ST Violet

The ShiverPeaks BS77907/4 20m ST Violet is an OM4 multimode fibre optic cable designed for high-bandwidth network links. With a 50 µm core diameter and ST connectors on both ends, this full-duplex cable supports reliable, low-attenuation transmission over a 20-metre run. Its violet jacket provides easy visual identification in patch panels and rack environments, and the OM4 grade ensures performance suited to modern data center and enterprise networking equipment.

Advantages

This fibre optic cable delivers high modal bandwidth and low insertion loss characteristic of OM4 multimode fiber. ST connectors offer secure push-and-twist coupling for stable connections in equipment that accepts bayonet-style terminations. The 20 m length provides flexibility for inter-rack and room-to-room links while maintaining signal integrity for short- to medium-distance runs. The coloured jacket simplifies cable management and rapid identification during installation and maintenance.

Suitable for

• Data centre interconnects and server-to-switch links
• High-speed LAN backbones and enterprise network segments
• Audio-visual systems and broadcasting where multimode OM4 fibre is specified
• Patch panels, cross-connects, and lab test setups

Key specifications

• Fibre type: OM4 multimode
• Core diameter: 50 µm
• Connector type: ST on both ends (bayonet-style)
• Length: 20 metres
• Transmission mode: Full duplex
• Jacket colour: Violet for easy identification

How to use

Verify that the connected devices accept ST multimode interfaces and that the OM4 specification is compatible with your transceivers or fibre modules. Route the cable avoiding sharp bends; maintain minimum bend radius recommended for multimode fibre to prevent increased attenuation. Insert each ST connector into the corresponding receptacle and secure with the bayonet twist until seated. Use dust caps when connectors are not in use and clean connector endfaces with appropriate fibre cleaning tools before making connections to ensure optimal signal quality.

Usage recommendations

For best performance, pair this OM4 cable with matched multimode transceivers and maintain proper fibre handling procedures: avoid over-bending, use strain relief where required, and regularly inspect and clean connector endfaces. Use the violet jacket to organise and document fibre runs in patch panels to simplify troubleshooting and routine maintenance.
