Description
Core Product Summary
The Matrox ET-436-A-FX-R2-SR-16GB-NOV is a high-performance IP KVM transmitter module from the Matrox Extio 3 Series (Extio N3408 architecture). Designed for secure, low-latency remote operation in critical control room environments, this unit captures multi-display computer workstation outputs—supporting up to four 1080p displays or a single 4K60 4:4:4 video feed—and transmits them over standard 10GbE or 1GbE IP networks via fiber-optic SFP+ transceivers.
Built for continuous industrial, broadcast, energy, and defense control room deployments, the transmitter processes keyboard, video, mouse, USB 2.0, and analog audio signals with minimal latency. It incorporates Matrox’s proprietary ultra-low bitrate compression technology, enabling high-quality, pixel-perfect desktop extension over LAN or WAN infrastructure without consuming excessive network bandwidth.

Detailed Product Overview
The Matrox ET-436-A-FX-R2-SR-16GB-NOV serves as an essential hardware extension endpoint in high-security, high-density control room installations. By separating user workstations and host PCs from operator desks, facilities can centralize noisy, heat-generating computer hardware in secure server rooms while providing operators with uncompromised, real-time desktop performance at remote consoles.
Utilizing Matrox’s advanced IP encoding technology, the Extio 3 transmitter compresses multi-stream DisplayPort video and USB peripherals into a low-bandwidth IP stream that travels over standard fiber-optic network infrastructure. The inclusion of a Short-Range (SR) SFP+ optical module allows secure, galvanically isolated signal transmission across multimode fiber links, immune to electrical noise and ground loops common in industrial plants.
System integrators can deploy Extio 3 units as direct point-to-point extenders or integrate them into a managed matrix switching architecture using standard COTS (commercial off-the-shelf) network switches and the Matrox Extio Central Manager software.
Dimensions, Mounting & Connection Notes
- Physical Form Factor: Compact desktop enclosure; can be rack-mounted using optional Matrox Extio 3 rack-mount shelves (up to two units in 1U space).
- Host Video Wiring: Connect mini-DisplayPort cables from the workstation GPU to the four mDP input ports on the transmitter’s rear panel.
- Fiber Network Link: Insert the included SR multimode SFP+ transceiver module into the SFP+ cage and connect LC multimode fiber cabling to the IP network or direct receiver link.
- Cooling & Airflow: Ensure adequate ventilation around the unit when installing in high-density server racks to maintain operation within rated thermal limits.
