Fiber optic patch cable QOLTEC 54061, 3 m, SC to ST, 9 µm core, yellow

QOLTEC 54061 is a 3 m single-mode fiber optic patch cable designed for connecting network equipment with SC and ST interfaces. The cable features a 9 µm core for single-mode transmission and a yellow jacket for clear identification in wiring bundles. It is suitable for data centers, telecom environments and enterprise LANs where reliable, low-loss fiber links are required. The cable uses a low-smoke zero-halogen (LSZH) outer sheath to limit harmful emissions in the event of fire, and each unit is individually tested to ensure performance on high-speed optical transmission networks.

Advantages

This patch cable combines single-mode 9 µm core performance with industry-standard SC and ST connectors to provide stable optical links across active devices, transceivers and fiber panels. The 3 m length offers flexibility for short patching runs while the yellow jacket simplifies identification and routing in fiber trays. The LSZH sheath reduces the risk of toxic gas emission during a fire and contributes to compliance in sensitive installations. Individual factory testing ensures each cable meets insertion loss and continuity expectations for dependable operation.

Suitable for

• Connecting switches, media converters and SFP/SFP+ transceivers with SC and ST ports
• Patch panels and fiber distribution frames in data centers and server rooms
• Telecommunication links and enterprise LAN backbone connections
• Short-distance patching between equipment racks and network cabinets

Key specifications

• Cable type: single-mode optical fiber with 9 µm core
• Length: 3 m
• Connectors: SC (one end) to ST (other end)
• Jacket colour: yellow for easy identification
• Outer sheath: LSZH (low-smoke, zero-halogen)
• Testing: individually tested for optical continuity and performance

How to use

Route the cable through cable management pathways or trays, avoiding tight bends and sharp edges to maintain the fiber's bend radius. Insert the SC connector into the corresponding SC receptacle until it clicks and secure the ST connector by aligning the bayonet and twisting until it locks. Confirm link status on connected equipment and, if available, verify signal quality with an optical power meter or transceiver diagnostics. When removing the cable, gently unlock the ST connector before pulling and always cap exposed connectors if not in use to prevent contamination.

Usage recommendations

Handle connectors by the housing and keep end faces clean; use dust caps when storing unused cables. Maintain a minimum bend radius as specified by standard single-mode fibers to avoid increased attenuation. For installations in public or confined spaces, prefer LSZH-sheathed cables like this model to reduce smoke and corrosive gas emission risks during fire incidents.
