High-Frequency Shielded Cable
High-Frequency Shielded Cable is a telephone cable designed for bidirectional pulse code modulation (PCM) transmission. Compared to other cables, this cable offers superior near-end crosstalk attenuation at test frequencies of 1024 kHz (30 channels) and 772 kHz (24 channels), achieving a 100% acceptance factor for PCM transmission.
Applicability:
A high-frequency shielding tape divides the cable core into two sections, making it suitable for all filled and unfilled cables for PCM transmission.
Construction:
High-Frequency Shielding Tape: 0.1mm thick, double-sided aluminum tape.
Cable Core Structure: Using 25 pairs as the basic unit, a high-frequency shielding tape is placed within the cable core, dividing the entire core into two, ensuring an equal number of pairs on each side of the shielding tape. Available shielding types include "C," "Z," and "D."
