Yellow 2 m singlemode duplex fibre cable with LC and ST connectors

Lumenzi

Lumenzi FC-OS1LCST-2-YL-1 LC/ST Singlemode Duplex Fibre Optic Cable 2 m

SKU CH-5CPF-FCVJ0

Connects network equipment with LC and ST ends using 9/125 µm singlemode fibre rated for ≤ 0.35 dB insertion loss and ≥ 55 dB return loss over 2 metres

  • TypeFiber Patch Cable
  • ColorYellow
  • Length2 Meter
  • SpecificationsSeries: LC/ST Fiber Type: Singlemode Core/Cladding Diameter:
  • Low insertion loss with ≤ 0.35 dB per connector
  • High return loss at ≥ 55 dB for clean signals
  • Singlemode 9/125 µm fiber minimises loss over distance
  • OS1 compliant for broad singlemode device compatibility
  • Hybrid LC/ST duplex connectors suit mixed-port environments

LC/ST Singlemode Duplex Cable

This 2 metre patch cable joins LC and ST interfaces in one assembly, giving network engineers a single lead for mixed connector panels. Yellow jacket colour identifies singlemode fibre at a glance. It suits data-centre cross-connects, telecom distribution frames and enterprise backbone links where both connector types appear.

9/125 Micron OS1 Upgrade Path

Replaces legacy multimode jumpers when distance or bandwidth exceeds multimode reach. The OS1-rated 9/125 micron core supports extended-range transmission with insertion loss ≤ 0.35 dB per connector and return loss ≥ 55 dB. The jump is worth it when linking buildings, campuses or long-haul equipment rooms that demand singlemode performance.

UPC Polish Duplex Build Integration

UPC ferrules mate cleanly with standard LC and ST adapters, requiring no special tooling or adapter panels. Duplex construction carries transmit and receive fibres in one sheath, freeing rack space and reducing cable-management bulk. The flexible connector design fits dense patch panels and wall-mounted enclosures alike.

Questions about this item

What are the connector types on each end of this 2 m singlemode duplex cable?

One end has an LC connector and the other end has an ST connector, providing a hybrid interface for mixed network equipment.

What is the correct polishing style to ensure the rated return loss of 55 dB?

Both connectors use UPC ferrules; clean the end faces before mating and fully seat each connector to maintain the specified return loss.

When should this patch cord be replaced to maintain insertion loss below 0.35 dB?

Replace the cable if end-face inspection shows scratches, contamination that cannot be cleaned, or if link tests report loss exceeding the rated threshold.
