  • OS2 single-mode fiber supports 40 Gbps long-distance links
  • SC/UPC connectors on both ends ensure low-return-loss mating
  • 9/125 µm core/cladding diameter matches standard single-mode infrastructure
  • Duplex construction provides separate transmit and receive fibers
  • 3 m (9.8 ft) length fits typical rack-to-panel runs

Single-mode duplex cable

The StarTech SMDOS2SCSC3M is a 3 metre OS2 single-mode duplex fiber optic cable built for long-distance network links. It uses SC/UPC connectors on both ends and a 9/125 µm core/cladding profile suited to campus and metro spans.

40 G headroom

Rated for 40 G throughput, the cable handles high-bandwidth backbone traffic with margin for future upgrades. Attenuation limits on single-mode glass mean very long runs are possible, though splices, patch panels and tight bends will reduce reach before the fiber itself does.

SC/UPC connector match

The duplex SC/UPC interface is the deciding factor — this cable only fits ports and patch panels that accept SC connectors with UPC polish. Installations using LC, ST, FC or APC polish need a different assembly.

Questions about this item

Will this SC/SC duplex cable connect directly to the SC ports on my existing single-mode patch panel?

Yes, both ends terminate in SC UPC connectors so the cable plugs straight into standard SC single-mode ports on patch panels or transceivers.

How can I verify the 3 m OS2 link is performing correctly after installation?

Connect a compatible 40 G single-mode transceiver at each end and confirm the link establishes with no errors reported by the attached networking equipment.

Does the package include any dust caps or cleaning tools, or must I purchase them separately?

The cable ships with protective dust caps fitted on both SC connectors; cleaning tools and additional caps are not included and must be bought separately.
