Why choose it

OM4 fibre supports 10GbE, 40GbE and 100GbE up to 150 metres, making this cable a future-proof choice for backbone and server connections. The LSZH jacket reduces toxic smoke in case of fire, and the heather violet colour follows industry colour-coding for OM4.

Ideal use cases

• Data centre interconnects between switches and patch panels
• High-speed storage area networks
• Enterprise backbone links

Good to know

The duplex configuration uses two fibres for bidirectional communication. ST connectors feature a bayonet-style twist lock, ensuring a secure connection in vibration-prone environments.
