Frequently Asked Questions
What is a multimode fiber extender and why use one?
A multimode fiber extender transmits video, audio, and control signals over fiber optic cables instead of copper, enabling distances up to 1500 feet without signal degradation. Fiber eliminates electromagnetic interference (EMI) and RF noise, making it ideal for secure, long-distance professional installations in broadcast, security, and control room environments.
Can the SFXPRO-4P-M-S extend multiple DVI-D signals simultaneously?
Yes. The 4-port DVI-D extender supports four independent DVI-D video channels, stereo audio, USB, and RS-232 control—all transmitted simultaneously over a single multimode fiber connection, providing complete AV and peripheral control extension.
How far can this fiber extender transmit signals?
This fiber extender transmits signals reliably up to 1500 feet over multimode fiber with zero signal loss, making it suitable for large facilities, inter-building connections, and distributed control systems where standard copper cable solutions are impractical.
Is the SFXPRO-4P-M-S compatible with legacy systems?
Yes. The integrated RS-232 serial control port enables seamless integration with legacy control systems, KVM switches, and automation platforms, while USB 2.0/1.1 support ensures compatibility with modern peripherals and devices.
