Product Overview
The FQ-CVT108 Series 8-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 reliable data transmission.
The converter features eight physically isolated 100/1000Mbps full-duplex RJ45 Ethernet ports and a 10G SFP+ optical uplink. Using high-speed TDM transmission technology, each network port is assigned an independent Gigabit transmission channel.
The physical isolation design helps eliminate crosstalk between different network subsystems and prevents interference or data leakage between independent data channels. This makes the converter particularly suitable for surveillance systems, LED display networks, and other multi-channel Ethernet applications.
The FQ-CVT108 Series is available in Non-PoE and PoE versions. The PoE version supports IEEE 802.3af and IEEE 802.3at, allowing compatible network devices to receive both data and power through the Ethernet cable.
With a fanless design, surge protection, ESD protection, and desktop installation, the converter provides reliable operation for long-term network deployment.
