Lenovo 4X91U42988 InfiniBand/glasvezelkabel 0,4 m QSFP zwart

The ThinkStation PGX QSFP Link Cable is a compact, hot-swappable interface designed for high-speed data transmission in networking and storage applications. It supports data rates of up to 200 Gbps and enables direct QSFP-to-QSFP connections between PGX devices or between a PGX device and a network switch. The Lenovo 4X91U42988 network card is a wired card with a fiber interface and a maximum data transfer rate of 112 Mbit/s, intended for reliable LAN connectivity and point-to-point fiber links in systems that require a modest dedicated fiber connection.

Advantages

The cable provides a hot-swappable QSFP interface for flexible installation and maintenance without powering down equipment. It supports direct device-to-device and device-to-switch connections, enabling straightforward integration in environments that use PGX modules. The Lenovo network card offers a fiber interface and wired connectivity suitable for stable point-to-point transmission where modest bandwidth is sufficient.

Suitable for

• Establishing QSFP direct links between two PGX devices
• Connecting a PGX device to a network switch via QSFP
• Systems requiring a wired fiber network interface
• Environments needing stable point-to-point fiber connections with moderate bandwidth

Key specifications

• Interface type: QSFP (for the PGX link cable) and fiber interface (for the network card)
• Form factor: compact, hot-swappable (link cable)
• Maximum data rate: up to 200 Gbps (link cable); up to 112 Mbit/s (network card)
• Connectivity: wired, fiber
• Intended use: networking and storage applications; server component compatibility

How to use

Insert the QSFP connectors into compatible PGX modules or QSFP ports on a network switch while the equipment is powered as the link cable is hot-swappable. For the network card, install the card into the appropriate server or workstation slot and connect the fiber cable to the card’s fiber interface. Configure network settings on the host system according to your LAN requirements to enable point-to-point or switch-based communication.

Recommendations

Use the QSFP link cable in systems that support QSFP interfaces and PGX modules; verify port compatibility and supported data rates before deployment. For the Lenovo fiber network card, ensure the connected fiber infrastructure and network configuration match the card’s intended usage and bandwidth capabilities.
