Why choose it

The aqua jacket instantly identifies this as an OM3 cable, preventing mix-ups with older OM1/OM2 cables. Duplex construction with two fibres supports bidirectional communication, and the ST connectors feature a bayonet-style twist lock for secure connections in high-vibration environments.

Ideal use cases

• Connecting switches, routers, and servers in data centres
• 10 Gigabit Ethernet backbone links up to 300 m
• Fibre Channel storage area networks
• Legacy ST infrastructure upgrades requiring OM3 performance

Good to know

OM3 fibre is laser-optimised for VCSEL transceivers, ensuring reliable performance at 10 Gb/s. The PVC jacket is durable and flame-retardant for indoor use. This cable is ideal for installations where ST connectors are already deployed, eliminating the need for adapters.
