Single-port single-mode gigabit fiber optic network card

A single-port, single-mode gigabit fiber optic network card provides 1 Gbps connectivity over long-distance fiber using SFP or SC connectors, ideal for servers and enterprise networks.

Key Features

Speed and Performance: Supports 1 Gbps (1000 Mbps) full-duplex operation, with some cards offering up to 2000 Mbps total bandwidth through full-duplex mode, ensuring high-speed data transfer for demanding applications.

Single-

Mode Fiber Support: Designed for single-mode fiber, enabling long-distance transmission (typically 10–40 km depending on the module and card) with minimal signal loss. Connector Types: Commonly uses SFP (Small Form-factor Pluggable) or SC/LC connectors, allowing flexibility in choosing compatible fiber modules or transceivers. Interface and Compatibility: Most cards use PCIe x1 slots but are compatible with x4, x8, and x16 slots.

They support a wide range of operating systems including Windows (7–10, Server editions), Linux (kernel 2. 6–4.x), FreeBSD, and VMware ESXi. Advanced Features: Many professional-grade cards include VLAN filtering, TCP/UDP checksum offload, TCP segmentation, Jumbo Frame support, and traffic management, reducing CPU load and improving network efficiency.

Plug-and-

Play Installation: Designed for easy installation with minimal configuration, often including gold-plated contacts for durability and heat sinks for stable operation in high-temperature environments.

Use Cases

Data Centers: Ideal for connecting servers to high-speed fiber networks, reducing bottlenecks in storage or compute clusters. Enterprise Networks: Provides reliable long-distance connectivity between buildings or across campuses using single-mode fiber. Network Upgrades: Suitable for migrating from copper Ethernet to fiber infrastructure while maintaining backward compatibility with existing SFP modules.
