Network Cable TE Connectivity Duplex-Patchkabel 50/125 1m 2xST/2xSC

The TE Connectivity Duplex-Patchkabel 50/125 1m 2xST/2xSC is a multimode fiber patch cable designed for optical network connections. With a 1 metre length and duplex construction, it carries two parallel multimode fibers with a 50/125 µm core/cladding dimension. The cable terminates in two ST connectors on one end and two SC connectors on the other, allowing direct interfacing between equipment that uses ST and SC terminations. It is intended for short-range high-bandwidth links within structured cabling systems in office, server room and local network environments.

Advantages

This duplex multimode cable provides consistent optical performance for short-distance links, benefiting from standardized 50/125 µm fiber geometry and factory-polished connectors. The mixed connector configuration (2xST to 2xSC) eliminates the need for additional adapters when connecting devices with differing connector types. Its 1 m length reduces excess cable slack in patching panels and rack-to-equipment connections, and the robust connector housings ensure reliable mating cycles and stable signal transmission.

Suitable for

• Patch cords between switches, patch panels and transceivers in local area networks
• Interconnection of equipment using ST and SC optical ports
• Short-range multimode optical links in data centres and telecommunications rooms
• Laboratory or test-bench setups requiring reliable multimode fiber patching

Key specifications

• Fiber type: Multimode 50/125 µm
• Length: 1 m
• Construction: Duplex (two fibers)
• Connectors: 2x ST to 2x SC
• Polish type: Factory polished end faces (standard PC/UPC depending on variant)
• Typical applications: Short-range multimode data links, patching

How to use

Identify the ST and SC ports on the devices to be connected and align the duplex cable so that each fiber corresponds to the correct transmit and receive ports. Insert the ST connectors by aligning the bayonet mount and twisting to lock; insert the SC connectors with a push-pull action until they click into place. Avoid sharp bends in the cable and maintain the recommended minimum bend radius for multimode fiber to preserve optical performance. When disconnecting, reverse the connector removal steps and store the cable in a protective sleeve or coiled loosely to prevent microbends.

Usage recommendations

For best performance, keep connector end faces clean and inspect them with a fiber inspection scope before installation. Use dust caps when connectors are not mated and avoid repeated unnecessary mating cycles. For links beyond the intended short-range multimode distances, consider singlemode cabling or appropriate transceivers.
