Interná optická sieťová karta Inter-Tech LR-9802BF-2SFP+

The Inter-Tech LR-9802BF-2SFP+ is an internal fiber network card engineered for high-speed wired connectivity in desktop and server systems. It provides fiber-optic links via two SFP+ ports and a PCI Express host interface for direct integration into compatible motherboards. With support for data transfer rates up to 10000 Mbit/s, the card is suitable for environments that require stable, low-latency network connections and enhanced throughput compared with typical copper-based NICs.

Advantages

The card delivers multi-gigabit fiber connectivity through SFP+ ports and uses a PCI Express interface to minimize latency and maximize bandwidth. Its compact internal design occupies a standard expansion slot and has a low physical weight. The LR-9802BF-2SFP+ provides a reliable wired solution that reduces electromagnetic interference associated with copper cabling and supports long-distance links when used with appropriate transceivers and fiber cables.

Suitable for

• High-performance workstations and servers requiring fiber connectivity
• Data center uplinks and aggregation where SFP+ ports are needed
• Low-latency networking applications such as virtualization and storage access
• Environments with long-distance network segments using optical fiber

Key specifications

• Maximum data transfer rate: 10000 Mbit/s
• Host interface: PCI Express
• Port type: 2 × SFP+ (fiber)
• Form factor: internal PCIe expansion card
• Typical use: wired optical network connectivity
• Physical weight: 0.11 kg

How to use

Install the Inter-Tech LR-9802BF-2SFP+ into an available PCI Express slot on a powered-down system following standard anti-static procedures. Secure the card in the chassis expansion slot and connect compatible SFP+ transceivers and fiber-optic cables to the SFP+ ports. Power on the system and install any required drivers provided by the operating system or the card vendor. Configure network settings in the host operating system or network management software to assign IP addresses, set link speeds, and enable any offload or advanced features supported by the platform.

Recommendations

Use certified SFP+ transceivers and appropriate grade fiber cable (single-mode or multi-mode) that match the transceiver specifications. Ensure the motherboard supports the required PCI Express lane configuration for optimal performance, and keep system firmware and drivers up to date to maintain compatibility and stability.
