Product Description & Overview
This advanced Fiber Optic Extender delivers comprehensive signal integration for modern IP-based
video systems, combining high-density Power over Ethernet with multi-channel SDI video transmission
through single-mode fiber infrastructure. The system features 8 Gigabit PoE ports compliant with IEEE
802.3af/at standards, 6 channels of forward 3G-SDI transmission, and 2 channels of backward 3G-SDI
return video, all consolidated through a single fiber connection. This integrated approach provides a
complete solution for systems requiring simultaneous power delivery, network connectivity, and high-
quality video transmission.
Engineered for superior performance in demanding environments, the extender supports uncompressed
digital video transmission across multiple standards including SDI (270Mbps), HD-SDI (1.485Gbps), and
3G-SDI (2.97Gbps) while maintaining broadcast-quality signal integrity. The intelligent PoE system
automatically detects and powers compatible devices while safely connecting to non-PoE equipment,
providing flexible deployment options for various connected devices. The fiber optic transmission technology
ensures complete immunity to electromagnetic interference, ground loops, and signal degradation, significantly
enhancing system reliability and security compared to traditional copper-based solutions.
The extender supports transmission distances up to 20 kilometers, making it ideal for large-scale
deployments in broadcast facilities, surveillance networks, and live event production environments.
This extended reach capability enables centralized management of distributed camera systems while
maintaining pristine video quality and reliable network connectivity. The solution is particularly valuable
for HD surveillance systems requiring remote camera powering, live broadcasting applications needing
bidirectional video communication, and large-scale AV installations where signal integrity and power
delivery are critical. By integrating multiple functionalities through a single fiber connection, this system
reduces infrastructure complexity while providing robust, interference-free operation that surpasses the
limitations of conventional coaxial and Ethernet-based systems, establishing new standards for integrated
video and power transmission in professional applications.
