Yes, I agree with you.
I did a simple AI query on the reasons to use shorter cables. We all agree AI can make mistakes, but I think the response is solid 
Making an electric conductor (like a LAN cable) as short as possible minimizes signal degradation and electrical losses. Keeping data cables short ensures high-speed performance and reliability. [1, 2, 3, 4]
🔴 Attenuation and Signal Loss
- Resistance: Longer wires have higher electrical resistance.
- Voltage Drop: Resistance causes signal voltage to drop over distance.
- Energy Dissipation: Heat loss increases with longer cable lengths.
- High Frequency: Network signals use high frequencies that decay faster. [1, 2, 3, 4, 5]
🔴 Capacitance and Inductance
- Parasitic Capacitance: Long parallel wires naturally store unwanted electrical charge.
- Signal Distortions: This stored charge rounds off sharp digital pulses.
- Inductance: Longer wires create a stronger unwanted magnetic field.
- Impedance Mismatch: Increased length alters the cable's native impedance. [1, 2, 3]
🔴 Interference and Noise
- Antenna Effect: Longer cables act like large antennas picking up noise.
- EMI: Cables absorb more Electromagnetic Interference from nearby electronics.
- Crosstalk: Internal wires bleed signals into adjacent wires over distance.
- SNR Drop: Signal-to-Noise Ratio decreases as noise accumulates along the length. [1, 2, 3, 4, 5]
🔴 Propagation Delay and Timing
- Latency: Electrical signals take time to travel down a conductor.
- Phase Shifting: High-frequency components shift out of sync over distance.
- Jitter: Timing variations increase, causing data packet errors.
- Collision Detection: Ethernet protocols rely on strict timing windows to manage data. [1, 2, 3]
