LR-LINK Fiber Patch Cable SC-SC Single-Mode Duplex 1/3/5m

SKU CH-TCQQ-GPYDR

Single-mode duplex SC-SC fiber patch cable for connecting SFP transceivers in optical networks, available in 1, 3 or 5 metre lengths

  • Low insertion loss for minimal signal attenuation
  • High return loss to reduce signal reflections
  • Durable PVC jacket resists wear and deformation
  • Ceramic connectors ensure reliable low-loss connections
  • Compatible with standard fibre equipment for plug-and-play use

SC-SC single-mode duplex cable

This SC-to-SC single-mode duplex patch cable connects SFP transceivers and other standard fibre equipment in optical networks. It is built for fast Ethernet and Fibre Channel links where low insertion loss and high return loss are required. The cord uses a PVC jacket and ceramic ferrules for reliable, low-loss transmission.

Behaviour under sustained load

Low insertion loss keeps signal attenuation minimal during continuous data transmission across the link. High return loss reduces reflections that can degrade performance over long runs. Ceramic connectors maintain stable optical alignment, while the PVC sheath resists wear and deformation in permanent installations.

Upgrade path and fit

The cable replaces older or damaged duplex jumpers in single-mode infrastructures and extends reach with 1 m, 3 m or 5 m length options. It suits technicians who need plug-and-play compatibility with all standard fibre gear. Buyers who require multi-mode fibre or different connector types such as LC or ST will need a different patch cord.

Highlights

  • Low insertion loss for minimal signal attenuation
  • High return loss to reduce signal reflections
  • Durable PVC jacket resists wear and deformation
  • Ceramic connectors ensure reliable low-loss connections
  • Compatible with standard fibre equipment for plug-and-play use

Questions about this item

Does this SC-SC single-mode duplex patch cord generate any heat or draw power during continuous use?

No, the cable is a passive optical component with no active electronics, so it produces no heat and consumes no power regardless of how long it runs.

What equipment must I already have to use this SC-SC single-mode duplex jumper?

You need two devices with SC single-mode ports — such as SFP transceivers, media converters or switch modules — plus matching single-mode fibre infrastructure.

Will this yellow single-mode duplex lead work with the older orange multimode patch panel in my rack?

No, single-mode and multimode fibres have different core sizes and are not intermateable; you would need single-mode adapters or a mode-conditioning patch cord for that connection.
