Keep legacy coax working for modern networked devices. The Altronix EBRIDGE100ST is a one-channel Ethernet-over-coax endpoint built for installations that need Fast Ethernet transport and passive PoE support without replacing the cable infrastructure. It is designed to work with EBRIDGE100 receivers, making it a focused solution for distributed edge deployments. This model is well suited to retrofit projects where the cost of new cabling, labor, or building access makes a full network rebuild unattractive. By using existing coax, it helps shorten installation time while preserving the value of installed infrastructure. Passive PoE support adds another layer of practicality for powering compatible endpoints in surveillance and access-control environments. For teams evaluating media conversion hardware, the EBRIDGE100ST stands out because it solves a specific problem cleanly: extend network reach over coax, keep power delivery simple, and avoid unnecessary hardware complexity. That makes it a strong fit when the deployment must be dependable, compact, and aligned to an existing Altronix EBRIDGE100 architecture.
