Ethernet Over Coaxial (EoC): Best Solution for Upgrading Existing Cabling to New Networks
In modern network deployments, long-distance transmission and upgrading legacy cabling are common challenges. The eZLink® Long-Distance Ethernet Over Coaxial (EoC) Transmitter offers an innovative solution that enables stable and secure data transmission using existing coaxial cables, twisted pairs, or any two-wire lines—while supporting PoE power delivery over distances of up to 1.5 kilometers.
A key advantage of eZLink® is its “no rewiring required” capability. This allows users to directly repurpose existing cables from analog CCTV systems and quickly upgrade to a digital IP camera environment, significantly reducing installation time and costs.
Whether for surveillance deployment, network extension in remote areas, or legacy system upgrades, eZLink® effectively solves the dual challenges of transmission distance and rewiring—enabling long-distance PoE and seamless system transformation in one step.
