4.1.2 Coaxial wiring
Coaxial cables will be used to connect access points that are more than 90 m from their network connection.
For renewal, it will be common to use existing coaxial cables regardless of their length for IP transport.
Commonly used coaxial cables have a characteristic impedance of 75 Ω.
Signals transported over coaxial wiring are historically analogue video signals. Use of Ethernet 10b2 type cables for
such signals been used for such signals, and new applications of DSL technology now allow Ethernet signals to be
transported over bifilar or + wires.
Coaxial link chains can be used to distribute signals over long lengths of cable with suitable end equipment. Depending
on the signals to be transmitted, they allow the use of T-connectors.
4.2 IP binding channel
4.2.1 IP link channel over Ethernet cable (point to point)
Each element should meet a minimum category for the IP channel to match the described class, as described in
Figure 2.

In operating mode, the following recommendations apply:
• Single equipment connection.
• Single cable connects installations, each equipment is connected by flexible patchcords.
• While additional breakpoints are possible but not recommended, it is important to note that they reduce bond
length performance.
As a reminder, from class D, the categories have been subdivided as in Table 2.
Table 2: Category (cable)
Category (cable) CAT5 CAT5e CAT6 CAT6a CAT7 CAT7a CAT7+

100 MHz 100 MHz 250 MHz 500 MHz 600 MHz 1 000 MHz 1 200 MHz
to standards)
Characterization frequency 200 MHz 200 MHz 450 MHz 550 MHz 900 MHz 1 200 MHz 1 500 MHz
Class (links) D D E Ea F Fa Fa

The use of CAT6 or CAT6A is recommended to improve the velocity of propagation of the signal to receiver at the
camera.
The patch cord should have a minimum section of AWG24 stranded copper (Not copper Clad Aluminium).
