STARTECH SMDOS2LCLC40M 40m 131ft LC to LC UPC OS2 Single Mode Duplex Fibre Optic Cable 9/125um

SKU CH-9EFS-G9GSX

A 40 metre OS2 single-mode duplex fibre cable with LC/UPC connectors for 9/125 µm links

  • 40 m reach for long-distance single-mode links
  • LC/UPC connectors ensure low-loss duplex connections
  • OS2 9/125 µm fibre supports high-bandwidth transmission
  • 131 ft length suits campus and data-centre runs
  • UPC polish reduces back-reflection for reliable performance

40 m LC/UPC OS2 single-mode duplex fibre

This 40-metre (131 ft) duplex cable uses OS2 single-mode fibre with a 9/125 µm core/cladding diameter. It is terminated with LC/UPC connectors at both ends for low-insertion-loss connections in long-distance links. The assembly is designed for campus, metro or data-centre runs where single-mode performance is required.

Indoor backbone runs needing single-mode reach

The cable suits installers building indoor backbone links, patch-panel cross-connects or equipment-room jumpers that demand OS2 single-mode performance over 40 metres. It is not intended for multimode OM1, OM3 or OM4 infrastructures, nor for outdoor direct-burial or aerial deployments where a ruggedised jacket is required. Buyers who need armoured cable, different connector polish angles or multimode fibre should select an alternative product.

9/125 µm OS2 single-mode fibre core

The defining specification is the 9/125 µm OS2 single-mode fibre core, which determines compatibility with single-mode transceivers and the maximum reach of the link. This core size distinguishes the cable from multimode alternatives and dictates the insertion-loss budget for the installation. Confirm that your transceivers and patch panels are specified for OS2 single-mode before ordering.

Questions about this item

Which devices need LC UPC ports to connect this 40m duplex cable?

Any network gear, media converters or patch panels fitted with LC UPC single-mode ports will accept the connectors on both ends.

Can this OS2 9/125µm cable link to legacy OS1 equipment?

Yes, OS2 is backward compatible with OS1 infrastructure; the 9/125µm core matches and the LC UPC connectors are identical.

How do I verify the 131ft link is live after installation?

Connect a light source and power meter at each end to measure insertion loss across both fibres and confirm continuity.
