Silkland Launches the First 1.5-Meter Passive Thunderbolt 5 Cable to Market

80Gbps bidirectional bandwidth, 240W USB PD 3.1 EPR, Intel certified – as of August 2026, the first available to consumers, exclusively at silklandtech.com

NEW YORK, Aug. 21, 2026 /PRNewswire/ — Silkland, a developer of high-performance connectivity solutions, announced the launch of its new 1.5-meter passive Thunderbolt 5 cable (Product Model: S3807), bringing a longer passive cable design to the latest Thunderbolt standard. Designed around advanced signal-integrity engineering, the cable combines silver-plated coaxial conductors and 100% shielding coverage to support high-speed Thunderbolt 5 performance without active signal amplification.

As Thunderbolt 5 raises connectivity performance to up to 80Gbps of bidirectional bandwidth and enables Bandwidth Boost of up to 120Gbps for display-intensive workloads, maintaining signal integrity becomes increasingly demanding. Silkland’s new cable addresses this challenge at the cable-construction level, using a low-loss coaxial signal path and comprehensive shielding to minimize signal attenuation and help resist electromagnetic interference.

Key Takeaways

• 1.5-meter passive design engineered for Thunderbolt 5 connectivity without active signal amplification
• Silver-plated coaxial conductors designed to minimize signal loss at high transmission rates
• 100% shielding coverage designed to strengthen resistance to electromagnetic interference
• Up to 80Gbps bidirectional bandwidth with Thunderbolt 5 Bandwidth Boost supporting up to 120Gbps for display-intensive workloads
• Up to 240W power delivery through USB Power Delivery 3.1 EPR

“The challenge was not simply reaching Thunderbolt 5’s bandwidth requirements, but maintaining signal integrity across a 1.5-meter passive connection,” said Vincent, CEO of Silkland. “We focused on the cable itself — from the conductor material and coaxial structure to comprehensive shielding — to develop a passive design capable of supporting the demands of next-generation high-speed connectivity.”

The cable supports up to 80Gbps of bidirectional bandwidth for high-speed data transmission. With Thunderbolt 5 Bandwidth Boost, compatible systems can provide up to 120Gbps of bandwidth for display-intensive applications, while maintaining 40Gbps of bandwidth in the other direction. This makes the cable suitable for demanding workflows involving high-resolution displays, external storage, Thunderbolt docks, gaming systems and professional workstations.

The cable also supports USB Power Delivery 3.1 EPR at up to 240W, allowing compatible devices to combine high-speed data, display connectivity and high-power charging through a single USB-C connection.

The new cable has passed Intel certification, validating its compatibility and performance within the Thunderbolt ecosystem. Certification provides an additional layer of assurance for users building high-performance USB-C systems around Thunderbolt 5-enabled computers, docks, displays and storage devices.

With its 1.5-meter length, passive architecture and advanced internal construction, Silkland’s new cable is designed to give users greater flexibility in arranging high-performance desktop and mobile setups while maintaining the capabilities expected from Thunderbolt 5 connectivity.

The Silkland 1.5M Passive Thunderbolt 5 Cable is now available on the Silkland Official Website for $59.99 USD.
