Planning electrical systems to be future-proof

I would generally lay all telecommunications cables replaceably inside the conduit. Unlike power cables, a different cable might be needed in the medium term.

Typical installation at APs is to mount a keystone module onto the installation cable and connect the keystone module to the access point using a short patch cable. For concrete ceilings, a box is needed to accommodate the cable section with the keystone, and the access point is mounted in front of the box. For a suspended ceiling, the too-long cable can be pushed into the ceiling cavity, so no box is needed.

If only the cable is sticking out of the ceiling, you will have a problem with the access point, since usually there is no space behind it for the cable piece, let alone the connector.

The installation cable is, as the name suggests, intended for installation inside the wall or conduit. A patch cable is the connecting cable between the device and the network socket (here a single keystone module). Getting a patch cable through a conduit is not so easy. The connector is very angular and large. Possible, but in my opinion sloppy work.

Plug on the cable is good. There is enough space, for example, at every Unifi access point (if the cable does not stick out of the ceiling directly 50cm long).

That’s why you don’t put a keystone module on the installation cable, but the RJ45 plug directly.

Plug onto the cable is fine. There is enough space, for example, at every Unifi Access Point

I can gladly send you my Unifi Access Point. There is no space for installation cables and field-terminatable connectors. Yes, there are Unifi Access Points that have a bit more space, but the space is not really generous, especially with regard to the very stiff installation cable.
