What Serial Cables does

Serial Cables is a privately held Colorado LLC (Serial Cables, LLC) founded in 2006 and headquartered in Englewood, Colorado, operating with a 1–10 employee footprint. The company designs and sells high-speed interconnect products—cable assemblies, retimers, redrivers, host adapter cards, adapters, and JBOF enclosures—for PCIe (Generations 4 through 7), NVMe, and CXL ecosystems, with stated signal-integrity performance up to 64 GT/s PAM4 and 64 GHz. Product portfolio is anchored on Gen6 validation hardware including the Hydra 8-bay passive E3 JBOF, the Hermes PCIe Gen6 Redriver line built around Phison PS7161 silicon, and the Gen6 x16 Atlas3 host card integrating Broadcom Talon 5 SerDes with on-board mCPU and a Python control API. Custom cable and board design services supplement the catalog with proprietary impedance-matched raw wires, ultrasonic-welded termination, and 3D-overlapped routing simulation, supported by PhD-educated SI engineers.

The company sells through a direct e-commerce storefront (serialcables.com) with unit pricing from roughly $79 to $4,995, a domestic sales team handling enterprise quotes and custom engagements, and six authorized regional distributors covering Hong Kong/China, South Korea, India, Taiwan, Israel, and Singapore/Malaysia. For more than 10 years, Serial Cables has been the exclusive Quarch Technology distributor for the US and Mexico, reselling Quarch Power Analysis Modules, Programmable Power Modules, hot-swap/fault injection tools, and cable testers, with native mezzanine integration into its own adapters and JBOFs. Customers include Broadcom, Intel, NVIDIA, Samsung, Dell, Qualcomm, Marvell, Astera Labs, Solidigm, Credo, and Phison—primarily semiconductor vendors, SSD/storage OEMs, and hyperscale-adjacent system builders validating AI and Gen6/NVMe/CXL infrastructure. Recent Gen6 product launches (Hydra November 2025, Hermes December 2025, MCIO Retimer Card February 2026) and an FMS 2026 booth indicate active positioning for the PCIe Gen6 transition, while founder Paul J. Mutschler continues to lead the firm without external institutional investors identified in the available data.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Credo Technology: Credo Technology designs high-speed connectivity silicon including retimers and DSPs for PCIe, Ethernet, and hyperscale data centers. Comparable to Serial Cables because Credo retimer silicon is integrated into Serial Cables' Gen6 retimer cards, making them commercially interlinked; Credo's AEC/ACC active cable products also directly compete with Serial Cables' high-speed cable assembly business in some configurations.
• Astera Labs: Astera Labs designs CXL, PCIe, and Ethernet silicon for cloud and AI infrastructure, including retimers and connectivity ICs. Comparable to Serial Cables as both companies target CXL/PCIe validation and deployment for AI infrastructure, and Astera Labs is listed as a Serial Cables customer and partner; however, Astera Labs is primarily a silicon vendor rather than a cable/adapter supplier.

Broad incumbents

• Keysight Technologies: Keysight is a leading manufacturer of electronic test and measurement equipment, including instruments used for signal integrity validation of PCIe, NVMe, and SAS. Comparable to Serial Cables' Quarch-distributed test equipment business and adjacent to its custom SI engineering services, though Keysight operates at vastly greater scale and across many industries beyond storage.
• Marvell Technology: Marvell is a major semiconductor vendor whose retimer and connectivity silicon is integrated into Serial Cables' Gen6 retimer cards, and Marvell is also a listed customer. Comparable to Serial Cables because they are co-dependent in the PCIe validation ecosystem, though Marvell is a broad incumbent serving data center, 5G, automotive, and storage end markets at scale far larger than Serial Cables.
• Amphenol: Amphenol is a large global interconnect manufacturer serving data center, storage, and telecom end markets with high-speed cable assemblies and connectors. Comparable to Serial Cables because both serve PCIe and storage interconnect demand, but Amphenol is a multi-billion-dollar incumbent with a vastly broader portfolio and customer base.
• Teledyne LeCroy: Teledyne LeCroy is a major manufacturer of oscilloscopes and protocol analyzers used for high-speed serial bus validation including PCIe. Comparable to Serial Cables because both serve the high-speed validation tooling market; Serial Cables' founder previously worked at LeCroy, and the companies target overlapping customer engineering teams at storage and semiconductor companies.
• Molex: Molex (a Koch subsidiary) is one of the largest global manufacturers of electronic interconnect products, including high-speed cable assemblies for PCIe, SAS, and storage. Comparable to Serial Cables as a competing supplier of PCIe/NVMe interconnects, but at far greater scale, broader SKU coverage, and serving a much wider customer base across data center, automotive, and industrial.
• TE Connectivity: TE Connectivity is a broad incumbent in electronic connectivity, including high-speed IO and storage interconnect products. Comparable to Serial Cables because it also sells PCIe and SAS cable assemblies and adapters to enterprise and data center customers, but operates at massive scale across many end markets beyond storage.

Direct peers

• Quarch Technology: Quarch Technology makes power analysis modules, programmable power modules, hot-swap/fault injection tools, and cable testers. It is directly comparable to Serial Cables because Serial Cables is the exclusive U.S./Mexico distributor of Quarch products and integrates Quarch PAM modules into its Gen6 adapters and JBOFs, making them commercially and technologically aligned rather than purely competitive.
• Samtec: Samtec is a leading manufacturer of high-speed board-to-board and cable interconnect products, with a well-known PCIe and SAS portfolio serving data center and storage customers. Comparable to Serial Cables as a direct competitor in PCIe cable assemblies and adapters, with broader product breadth but less specialization in PCIe Gen6/Gen7 validation tooling such as JBOFs and retimers/redrivers.
