Signalmanagement

Solutions:

Efficient Signalmanagement is Signalmanagement in modern AV and IT environments—whether in conference rooms, production facilities, or educational institutions.

Users often come across terms such as extender and switch, which describe completely different devices and therefore fulfill different tasks. A basic understanding helps to plan needs-based solutions and ensure the reliability and efficiency of signal distribution.

We clarify:

Extender

Extenders are used to transmit signals over greater distances than would be possible with standard cables.

Extenders usually consist of a transmitter and a receiver connected via another medium (e.g., Cat cable, fiber optics, or IP networks).

There are also signal conditioners. These are integrated in the middle of the cable route and recondition the signal. From there, the maximum cable length can be connected again.

USB-C HDBT3 Extender 4K60 Set

The USB-C HDBT3 Extender 4K60 Set transmits USB-C data and video signals as well as USB 2.0 signals.

It supports transmission up to 70m for 4K30Hz (4:4:4 8bit) and 40m for 4K60Hz (4:4:4 8bit) over a single CAT6A/7 cable. The transmitter has a USB-C input and 3 local USB device ports. There are 4 USB device ports available on the receiver. The USB-C input supports DP Alt-Mode standards (v1.2a), USB 2.0 data and up to 60 watts charging power.

The receiver has an HDMI output and 4 USB device ports. The transmission of RS-232 signals is also supported. The bidirectional 48 V PoC function allows power to be supplied to the transmitter or receiver.

AOC cable

Room size: ??? | Range: up to ??? m | Technology: ???

The AOC technology

Thanks to the use of fiber optic cables, AOC cables are insensitive to electromagnetic interference compared to copper cables. This is particularly advantageous in environments with many electrical devices (e.g. conference rooms, classrooms or at events). Touch displays in particular require stable and interference-free transmission of video signals and USB data for touch interaction. The USB-C AOC Full Featured cables from Kindemann fulfill both requirements. At the same time, the cables are particularly flexible and facilitate installation over long distances where copper cables reach their technical limits.

Compatibility and performance

The USB-C AOC cables support both the 4-lane DisplayPort Alt Mode with USB 2.0 and the 2-lane DP Alt Mode with USB 3.2 Gen2. This makes them compatible with almost all common devices and offers maximum flexibility. In 4-lane DP Alt Mode, all four SuperSpeed lines are used for DisplayPort signals, which doubles the maximum DisplayPort bandwidth. In this mode, however, data transmission is limited to USB 2.0. The 2-Lane DP Alt Mode uses two of the four SuperSpeed lines for DisplayPort signals and the remaining two lines for USB 3.2. This enables the simultaneous transmission of 4K video signals and USB data at up to 10 Gbit/s.

Supports peripheral devices

The new cables can not only transmit data and videos, but also allow connected peripheral devices to be charged with up to 60 watts. This means that they can simultaneously power laptops, tablets or other devices while they are in use. Typical applications for AOC cables are a variety of scenarios where reliability and functionality are crucial. For example, they support the full functionality of touch displays through the simultaneous transmission of image, sound, touch and data. In conference rooms, they offer a reliable solution for connecting modern notebooks and tablets with USB-C output, enabling smooth meetings.

Switch

“Switches” enable signals to be switched between multiple sources on a display or projector.

These can switch between the different inputs either manually or automatically.

In addition, modern switches often offer additional features such as integrated scaler processing and EDID management to further optimize signal quality and compatibility.
This makes them a key element when it comes to connecting different devices flexibly, reliably, and without delay.

KVM switch 21C

The KVM Switch 21C is ideal for connecting two sources to one display and various USB devices. This makes it easy to switch between UC equipment such as a video soundbar, camera, and Speakerphone even a mouse and keyboard.

Extender + Switch

These devices serve as both extenders and switches, combining two functions in one device.

You can extend signals over long distances while switching between multiple sources.
This reduces the number of devices required, simplifies installations, and increases flexibility—ideal for complex AV/IT environments with changing signal paths.

Differences between the signal types - HDMI - USB - USB-C

The most important signals in AV environments are HDMI, USB and USB-C signals. But what are the signals actually suitable for and how long can a cable be?

Feature	HDMI	USB	USB-C
Signal type	Audio + Video (digital)	Data (digital), power supply	Data, video, audio, power (digital, multifunctional)
Primary purpose	Transmission of image and sound	Peripheral connection (e.g. mouse, keyboard, data carrier)	Universal interface for data, video, audio, and power
Plug type	Type A, Type C	USB-A, USB-B, Micro-USB, Mini-USB	USB-C (symmetrical, small form factor)
Video transmission	Yes (up to 8K, depending on version)	No	Yes (via "DPAlt Mode")
Audio transmission	Yes	No	Yes (e.g. via USB Audio or DisplayPort Alt Mode)
Power supply	Minimal (for EDID, CEC etc.)	Yes (up to 4.5 W with USB 2.0, more with USB 3.x)	Yes (up to 240 W with USB Power Delivery 3.1)
Data transmission	No	Yes (up to 40 Gbps with USB 4)	Yes (USB 3.2, USB 4, Thunderbolt 3/4 possible)
Maximum cable length	Approximately 5–10 m (without extender)	approx. 5 m (USB 2.0), 3 m (USB 3.x)	approx. 1-2 m (depending on data rate and function)

With the USB-C interface, it should be noted that all features can be supported, but no feature has to be supported. When choosing a cable, pay close attention to which features are supported.

As maximum cable lengths are rarely suitable for practical use in conference rooms, educational establishments, etc., there are various options for extending the cable length.

HDMI copper - Active - AOC and Cat-Extender (Extender):

Cable type	HDMI	USB	USB-C Full Featured
Active cable	up to approx. 15 - 20 m	up to approx. 10 -15 m	up to approx. 5 m
AOC (Active Optical Cable)	up to 100 m	up to 15 m	up to 15 m
Cat extender (via CAT6a/7)	up to 100 m	up to 100 m	up to 100 m
