Product Description
The Allied Telesis B21F85 network adapter card serves as a bridge between fiber optic cabling and standard Ethernet networks, operating at a speed of 10 Megabits per second over fiber. This specialized adapter is designed for situations where existing fiber infrastructure needs to be integrated with contemporary 10/100 Mbps Ethernet environments. Its PCI form factor ensures compatibility with a wide range of older server and workstation systems that utilize the PCI bus architecture. This card is particularly useful in industrial settings, campus networks, or any location where the benefits of fiber optics, such as extended transmission distances and immunity to electromagnetic interference (EMI), are necessary. By converting the optical signal to an electrical Ethernet signal, the B21F85 allows devices connected via fiber to communicate seamlessly with devices on a standard twisted-pair Ethernet network, effectively extending the network's reach and capabilities. The 10Mb/s speed is indicative of its design for specific legacy applications or network segments where high throughput is not the primary requirement. It offers a cost-effective solution for maintaining connectivity and leveraging existing fiber investments without requiring a complete overhaul of the network infrastructure. The Allied Telesis B21F85 is a reliable choice for bridging these different network technologies.
