Twisted-pair design maintains signal quality
Posted: Sat Feb 22, 2025 8:30 am
One of the basic features of LAN cables is its twisted-pair design, which plays an important role in maintaining signal denmark mobile database during data transmission. This design reduces electromagnetic interference and crosstalk between cable pairs, ensuring stable data transmission.
The couple Line color duty Number of threads per inch
1 Blue/White-Blue Send/Receive 20-24
2 Orange/White-Orange Send/Receive 16-20
3 Green/White-Green No/PoE 12-16
4 Sugar/White-Brown No/PoE 8-12
Pairs 1 and 2 have tighter threads, providing better noise cancellation for important data transmission.
Shield options help protect against interference
Anti-interference measures in LAN cables include a variety of shielding options designed to maintain signal quality and reduce electromagnetic interference (EMI). Common shielding options include:
Unshielded Twisted Pair (UTP) – No shield
Foiled Twisted Pair (FTP) – Foiled
Shielded Twisted Pair (STP) – Shielded
Fully Shielded Twisted Pair (FSTP) – Fully shielded
Each type provides different protection, with FSTP providing the best EMI protection and is ideal for environments with high electrical noise.
Performance factors
The performance of a LAN cable depends on three key factors: speed capability, distance limitation , and shield performance.
Data transmission speeds vary greatly between cable types, with higher grades of cable typically providing faster data rates. Cable length directly affects signal quality and the actual amount of data that can be transmitted, while the presence and quality of shielding plays an important role in reducing electromagnetic noise and crosstalk, especially in environments with high electrical noise.
