Yellow duplex fibre cable with blue LC connectors on each end, one metre length

STARTECH

STARTECH SMDOS2LCLC1M 1m 3.3ft LC/LC UPC OS2 Duplex 9/125 LSZH fibre optic cable

SKU CH-ZWBN-3PCDF

A 1 metre OS2 single-mode duplex cable with LC/UPC connectors and LSZH jacket for 100G links

  • 1m length for short-range single-mode links
  • LC/UPC duplex connectors for standard patch-panel fit
  • OS2 9/125 fibre supports 100G transmission
  • Low insertion loss preserves signal integrity over distance
  • LSZH jacket reduces toxic smoke in fire risk areas

1m OS2 Duplex Fibre Cable

This 1-metre OS2 single-mode duplex cable connects two LC/UPC ports with 9/125 µm fibre. It suits data-centre patching, campus links and 100 GbE runs where low insertion loss matters. The LSZH jacket meets low-smoke safety requirements. Installers handling long-haul single-mode segments will use it daily.

Low Insertion Loss and LSZH Jacket

Factory-polished UPC ferrules keep insertion loss low across the 100 GbE budget. The LSZH sheath limits smoke and halogen emission in plenum or riser spaces. Passive construction draws no power and adds no active noise to the rack. Cable routing stays simple with the 1 metre length.

Replaces Damaged or Short Patch Leads

Swap out a worn LC/LC jumper or extend a run that falls short of the patch panel. The jump is worth it when an existing multimode lead cannot reach single-mode distance targets. It does not serve multimode OM3 or OM4 links, nor applications needing angled APC polish.

Questions about this item

How do I install the LC duplex connectors on this OS2 single-mode fibre cable without damaging the ferrules?

Remove the protective dust caps, inspect the ceramic ferrules for contamination, then insert each LC connector straight into the matching transceiver port until the latch clicks; avoid twisting the ferrule tip during insertion.

What cleaning or replacement will this LSZH OS2 jumper need over time?

Clean the LC UPC end-faces with a lint-free wipe and isopropyl alcohol before every re-mate; replace the cable if insertion loss rises above the link budget or if the LSZH jacket shows cracking or kinks.

At what point does insertion loss become the limiting factor on a 100 G link using this 1 m duplex cord?

The cable is rated for 100 G low insertion loss; the practical limit is reached when combined connector and fibre attenuation exceeds the transceiver's receive sensitivity, typically after multiple re-mates or if the end-faces are contaminated.
