## Summary description

Single-mode duplex fiber optic cable ProXtend with ST–ST UPC connectors, 0.5 m length and OS2 fibre (9 µm core). Prepared with male ST connectors for full-duplex links, suitable for short interconnects between networking devices, switches, media converters and patch panels in telecom and data center environments.

## Long description

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
 Fibre type: single-mode OS2 (9 µm core)
 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.
