Applications

10Base2 (Thin Ethernet) was the standard for LAN installations throughout the 1980s and 1990s. This adapter bridges legacy RJ11 cabling to BNC-based transceiver equipment and network interface cards. Commonly used in industrial control systems, telecommunications installations, and older enterprise networks that relied on coaxial cable infrastructure.

Condition: Used
This Fibronics FM040-RJMA-7 RJ11 to BNC transceiver adapter has been inspected and appears to be in good used condition. The adapter body shows light yellowing of the plastic housing typical of its age, and the label shows some wear, but the BNC connector and RJ11 port both look intact with no visible damage. It was pulled from a surplus networking environment. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
