Why choose it

The OS2 fibre is optimised for long-haul and high-speed backbone links, supporting wavelengths up to 1550 nm with low attenuation. The duplex design carries two fibres, enabling simultaneous transmit and receive channels for full-duplex communication. UPC polished connectors reduce back reflection, ensuring stable signal integrity in demanding network environments.

Ideal use cases

• Data centre interconnects between switches and patch panels
• Telecommunications central office and headend links
• Enterprise backbone cabling for campus networks
• Fibre-to-the-desk applications requiring singlemode performance

Good to know

The cable is 3 metres long, ideal for short rack-to-rack or intra-rack connections where excess slack is undesirable. Its yellow jacket conforms to industry colour-coding for singlemode fibre, simplifying identification in mixed-fibre environments.
