Internal Fiber Network Card Fujitsu PY-LA402 25000 Mbit/s PCI Express

The Fujitsu PY-LA402 internal fiber network card provides high-bandwidth wired connectivity for servers and workstations requiring low-latency, reliable links. With a PCI Express host interface and support for a maximum data transfer rate of 25000 Mbit/s, this card is engineered to integrate into systems that adhere to IEEE 802.3 networking standards. The compact internal form factor is intended for installation in compatible PCIe expansion slots to deliver stable fiber connections for data-center, virtualization, and high-throughput computing environments.

Advantages

The card delivers multi-gigabit fiber performance up to 25 Gbit/s over IEEE 802.3-compliant networks while using a PCI Express host interface for direct system integration and minimal overhead. Designed for wired fiber connectivity, it emphasizes consistent throughput and signal integrity suitable for continuous, data-intensive workloads. The internal design reduces external cable clutter and supports centralized network infrastructure within rack-mounted and tower systems.

Suitable for

• Data center servers and storage arrays requiring high throughput
• Virtualization hosts and hyper-converged infrastructure
• High-performance workstations for media processing and scientific computing
• Enterprise networking nodes and aggregation switches

Key specifications

• Connectivity technology: Wired fiber
• Host interface: PCI Express (PCIe)
• Maximum data transfer rate: 25000 Mbit/s
• Networking standards: IEEE 802.3
• Form factor: Internal PCIe expansion card

How to use

Install the network card into an available PCI Express expansion slot on a powered-down system following vendor safety procedures. Secure the card to the chassis and connect compatible fiber optic cabling to the card's external fiber port according to the fiber type and transceiver requirements used in your network. After physical installation, boot the host system and install any required drivers or firmware updates provided by the system or network administrator to ensure the card is recognized and configured for the intended network settings.

Recommendations

Use single-mode or multimode fiber and matching transceivers that comply with the deployed network design and IEEE 802.3 specifications. Verify PCIe slot bandwidth and host driver compatibility before deployment, and perform firmware updates to maintain stability and performance in high-throughput environments.
