PCI-E 16X 4.0 to PCI-E 16X 4.0 90 degree extension cable: an
efficient and stable data transmission expansion solution
In the era of rapid development of computer hardware, PCI-E
interface, as the core channel for high-speed data exchange between
devices, has attracted much attention for its performance and
flexibility. The PCI-E 4.0 standard promotes hardware ecosystem
innovation with a single channel transmission rate of 16 GT/s and a
theoretical bandwidth of 64 GB/s in both directions. The PCI-E 16X
4.0 to PCI-E 16X 4.0 90 degree extension cable, designed
specifically for space optimization and flexible wiring, provides
users with an efficient, stable, and adaptable data transmission
solution for complex scenarios with its unique elbow structure and
cutting-edge technology.
Core advantages of PCI-E 4.0 technology
1. High bandwidth transmission capability:
The PCI-E 4.0 standard increases the single channel transmission
rate to 16 GT/s, and in 16X channel mode, it can achieve a
theoretical bandwidth of 64GB/s in both directions, which is twice
as high as PCI-E 3.0. This performance enables the 90 degree
extension cable to easily handle bandwidth sensitive applications
such as real-time 4K video editing, loading of large game scenes,
and massive server data throughput, significantly reducing data
processing time and improving overall system response speed.
2.Enhanced signal stability:
PCI-E 4.0 adopts 128 b/130 b encoding technology, which embeds
verification information in the data to achieve real-time detection
and correction of transmission errors, reducing the bit error rate.
At the same time, optimizing signal drive strength and equalization
algorithms, combined with strict electrical parameter
specifications, reduces signal attenuation and distortion during
long-distance transmission, ensuring stable data transmission in
complex electromagnetic environments. The 90 degree extension cable
undergoes special signal processing at the bend to avoid signal
loss caused by angle changes and ensure the reliability of data
transmission.
3.Low latency architecture design:
By streamlining protocol processing and optimizing link management
mechanisms, PCI-E 4.0 significantly reduces data transmission
latency. For scenarios such as millisecond level operation feedback
in esports games and real-time command response from industrial
automation equipment, a 90 degree extension cable can ensure fast
data transmission and improve the real-time interaction performance
of the system. Its unique 90 degree design saves space without
affecting the low latency characteristics of data transmission.
4. Good compatibility:
PCI-E 4.0 has backward compatibility and can seamlessly collaborate
with PCI-E 3.0 and PCI-E 2.0 devices. Users do not need to replace
all components when upgrading hardware, and can gradually build
high-performance systems, reducing upgrade costs and promoting a
smooth transition of technology. The 90 degree extension cable also
supports compatibility with devices across generations and adapts
to hardware environments at different stages.
Analysis of PCI-E 4.0 Cable Technology
1. High quality conductor material:
The PCI-E 90 degree extension cable conductor uses 99.99% oxygen
free copper (OFC) with a resistivity of 0.0175 Ω· mm ²/m, which is
12% lower than ordinary copper materials and effectively reduces
signal transmission losses. Adopting a multi strand twisted
structure with a single strand diameter of 0.09mm, the skin effect
during high-frequency signal transmission is suppressed by
optimizing the twisted angle and pitch. At a rate of 16 GT/s, the
signal attenuation is controlled within -2.5dB/5GHz, meeting the
performance requirements of PCI-SIG for PCI-E 4.0 wire. At the
bend, the conductor undergoes special reinforcement treatment to
ensure the continuity of signal transmission.
2.High performance insulation layer:
The insulation layer is made of polyethylene (PE) foam material
with a dielectric constant of 1.5, which is 40% lower than
traditional materials and significantly reduces the dielectric loss
of signal transmission. Through precision extrusion technology, the
thickness of the insulation layer is precisely controlled at 0.18 ±
0.02mm, ensuring that the characteristic impedance of the wire is
stably maintained at 100 ± 3 Ω, effectively avoiding signal
reflection and crosstalk, and ensuring data integrity at a
bandwidth of 64GB/s. For the 90 degree bend, the insulation layer
is designed with increased flexibility to prevent damage caused by
repeated bending.
3.Double layer shielding system:
Due to the susceptibility of PCI-E 4.0 high-frequency signals to
interference, the wire adopts a double-layer shielding design:
Aluminum foil shielding layer: 0.012mm thick aluminum foil tightly wraps around the insulation
layer, with a shielding efficiency of 92% against low-frequency
electromagnetic interference;
Tin plated copper woven mesh: Tin plated copper mesh with a weaving density of ≥ 85%,
possessing good flexibility and conductivity, and a shielding
effectiveness of ≥ 55dB in the 1GHz frequency band
In the 90 degree bend area, a double-layer shielding layer is
reinforced to enhance the shielding effect and ensure stable signal
transmission in complex electromagnetic environments.
4. Precision connector technology:
The PCI-E connectors at both ends of the wire are made of PBT
engineering plastic material, which has high temperature resistance
(180 ℃) and impact resistance characteristics. The terminal adopts
a 3 μ m gold plating process, with a contact resistance of ≤ 60m Ω
and excellent oxidation resistance. The connector adopts a
differential signal independent isolation design internally, which
improves the crosstalk suppression ratio to above -30dB through
physical isolation and optimized wiring. The 90 degree elbow
connector adopts a unique L-shaped structure design, which ensures
the accuracy of signal transmission while facilitating installation
and disassembly in narrow spaces.
