Product Description
The DEC DEFLM-AA module is a specialized transceiver that bridges the gap between the Attachment Unit Interface (AUI) port found on many older Ethernet network interface cards and hubs, and the 10Base-FL fiber optic Ethernet standard. This allows devices with an AUI port to connect to fiber optic networks, which offer advantages such as increased distance, immunity to electromagnetic interference, and higher bandwidth potential compared to coaxial cable. Operating at a data rate of 10 megabits per second, this transceiver converts the electrical signals from the AUI port into optical signals for transmission over fiber optic cable, and vice versa. It typically uses SC duplex connectors for the fiber optic connection, providing a robust and reliable physical link. The module itself is designed to be compact and easily attachable to the AUI port of the host device. This transceiver was essential for extending Ethernet networks over longer distances or in environments where electrical noise could interfere with copper cabling. It represents a key component in the evolution of Ethernet, enabling the use of fiber optics for network backbone connections or for linking network segments that are geographically separated.
