Fiber optic duplex cable ProXtend ST–ST UPC OS2, 0.5 m, single-mode (9 µm), male connectors

ProXtend single-mode duplex fiber optic cable with ST–ST UPC male connectors, 0.5 m length and OS2 fibre (9 µm core) is designed for short interconnects in telecom and data centre environments. The cable supports full-duplex links between networking devices, switches, media converters and patch panels. The fibre uses a glass core optimized for single-mode transmission and the assembly is intended for reliable single-mode connections where ST UPC terminations are required.

Advantages

This ProXtend cable delivers single-mode transmission with OS2-grade fibre and ST–ST UPC terminations for low-loss connections in point-to-point links. The duplex format enables simultaneous transmit and receive channels for full-duplex operation. Its short 0.5 m length makes it suitable for neat rack and patch panel management, minimising excess slack while maintaining optical performance. The construction is compatible with standard ST-style male connectors and common single-mode networking equipment.

Suitable for

• Interconnects between switches and patch panels in server rooms and data centres
• Connections between media converters, transceivers and network appliances
• Short point-to-point single-mode links requiring ST–ST UPC terminations
• Cable management inside racks where a 0.5 m jumper is sufficient

Key specifications

• Connector type: ST–ST UPC, duplex, male connectors
• Length: 0.5 m
• Duplex format for full-duplex transmission
• Jacket: low-smoke zero-halogen (LSZH) compatible construction
• Operating temperature range: -20 °C to 70 °C

How to use

Route the duplex cable between the two ST-compatible ports, aligning the keyed ST connectors and push to engage the bayonet coupling until the connector locks. Ensure the transmit and receive fibres are correctly oriented at both ends to preserve full-duplex operation. Avoid tight bends and sharp kinks; maintain the manufacturer-recommended minimum bend radius. When not in use, keep connector end faces covered with dust caps to prevent contamination that can increase insertion loss.

Usage recommendations

Before installation, inspect and, if necessary, clean connector end faces with approved fibre cleaning tools. Use this 0.5 m duplex jumper for short patching inside racks or between adjacent devices; for longer distances select appropriately rated single-mode trunk or patch cables. Follow standard fibre handling safety and ESD precautions while working in network cabinets and data centre environments.
