Product Overview
The FQ-CVT104 Series 4-Port Gigabit Physically Isolated Fiber Media Converter is a high-performance Ethernet-to-fiber transmission device designed for LED display systems, surveillance networks, and applications requiring independent and secure data transmission.
The converter provides four physically isolated Gigabit Ethernet ports and a high-speed optical uplink. Using advanced TDM transmission technology, each Ethernet port is assigned a dedicated transmission channel, helping eliminate crosstalk between different network subsystems.
This physical isolation design is particularly suitable for surveillance systems and multi-network applications where independent data transmission is required. It helps prevent interference and reduce the risk of data leakage between different network channels.
The series is available in Non-PoE and PoE versions. The PoE version supports IEEE 802.3af/at and can provide power to compatible network devices through Ethernet cables.
The fanless design provides silent operation without mechanical cooling components, while built-in surge and ESD protection improves reliability in demanding network environments.
