Bending ethernet cable

I'm just about to route my Ethernet cable from my router all the way to my shed, however, I wanted to ask whether the bend of a cable can affect the transmission. I'll be bending the cable around my house many times as well as drilling through walls. The cable is roughly 40m long and is Cat 7.

Re: Bending ethernet cable

To be on the safe side keep the bend radius of the ethernet cable to a minimum of 25mm (1 inch).

Re: Bending ethernet cable

Broadly speaking, bending it is fine, although that's circular profile weatherproof cable, so you might have to accept slight bowing round corners rather than forcing to exactly a ninety degree fit, as doing that might compromise either conductors or insulation.  Bending cable is normally only a problem with coaxial cables, because distortion of the circular profile or kinking causes signal attenuation and internal reflections that raise noise levels.

Re: Bending ethernet cable

Considering ethernet cable consists of several twisted pairs of thinner cable I wouldn't be too concerned about bending:

Re: Bending ethernet cable

It isn't just about the cable core but also the insulating sheaths.

Too tight they stretch and may lose their insulating properties.

Always work on a minimum bend radius of 4 or 5 times the outer sheath diameter.

Re: Bending ethernet cable

The specification I have read is 10 x the outer diameter.
