Detail Information

Description :

FNXMU-M03K is an HDMI KVM fiber optical extender, which is consists of a transmitter unit and a receiver unit extends 1080p, 2 channel audio and 4 x USB 2.0 signals up to 70 KM over single one SC Duplex Single-Mode fiber cable and compatible with most popular resolutions. The leading-edge visual lossless technology allows 1080p, USB 2.0 long-distance transmission, and free of EMI interference.

The SFP modular so-called Small Form-factor Pluggable is a compact design used to provide cost-effective and instant connectivity. You can choose, replace, or swap the SFP based on the application, cable type, required range, and the desired data transmission rate.

Devices that support HDCP 2.2 (High-bandwidth Digital Content Production) are more likely to be only compatible with 4K UHD content. Most of the latest Rextron HDMI KVM/ Video Extenders support HDCP 2.2 and are particularly backward-compatible with previous versions. That means you can connect older sources to a new 4K TV under HD streaming with no HDCP 2.x to 1.x converter in between. Rextron KVM/Video extender with HDCP support ensures uninterrupted video playback at all times.

IR extension supports full frequency IR signals from 38KHz to 56KHz. Furthermore, the pigtail design of the IR extension unit with 1.4m cable increasing the distance between the emitter/ receiver heads and the IR port on the extender unit gives users a flexible and easier way in IR control system installation. That provides a unique strength which is often used in combination with home theater and system integration application.

USB 2.0 extension function enables users to transmit USB 2.0 signals over CATx/fiber optic cable with downward compatibility eliminating the USB distance limitation of 5 meters, it supports USB peripherals sharing without any software or driver installation. Dedicated USB 2.0 port on the front and rear side of the extender unit is suitable for both long-term and temporary USB peripherals access, allows users to attach or detach USB devices with ease.
