Server Accessories

A Server & Storage I/O cable refers to any data, power, or control cable used inside a server chassis to connect internal components such as CPUs, memory, storage devices, backplanes, expansion cards, and cooling systems. These cables are designed to support high signal integrity, efficient power delivery, and reliable operation in compact, high-density environments. Key Features: Data cables: Includes PCIe, MCIO, mini-SAS, SAS/SATA, and NVMe interconnects that provide high-speed communication between the motherboard, storage devices, and expansion modules. Power cables: Distribute power from the power supply unit (PSU) to various server components. Control and signal cables: Used for system management, fan control, LED indicators, and other internal functions. Form factor: Optimized for space-saving routing, low EMI (electromagnetic interference), and thermal efficiency. Typical Examples: PCIe riser cables for GPU or accelerator connections. MCIO or mini-SAS HD cables for NVMe or SAS storage backplanes. SATA power and data cables for HDDs or SSDs. Fan and sensor wiring harnesses. Applications: Internal data transfer within servers, storage systems, and high-performance computing nodes. Integration of modular components in blade or rack servers.

Active Optical Cable (AOC) is a type of cable that integrates optical fiber with electrical components to improve signal integrity and performance. AOC cables convert electrical signals into optical signals using embedded transceivers, enabling high-speed data transmission over longer distances compared to traditional copper cables. Key Features: Combines optical fiber and active electronics (transceivers) within the cable assembly. Supports high data rates (e.g., 10Gbps, 25Gbps, 40Gbps, 100Gbps ，200Gbps, 400Gbps, 800Gbps and beyond). Lightweight and thin compared to copper-based cables of equivalent length and speed. Reduced electromagnetic interference (EMI) and crosstalk. Typically used in data centers, high-performance computing (HPC), and storage networks. Typical Applications: Server-to-switch and switch-to-switch interconnects in data centers. High-speed interconnects in enterprise and cloud computing environments. High-performance computing (HPC) clusters. Storage area networks (SANs).

DAC Cable (Direct Attach Copper Cable) A Direct Attach Copper (DAC) Cable is a type of high-speed cable assembly that uses copper conductors to transmit data directly between devices. DAC cables have integrated transceivers at both ends, eliminating the need for separate optical transceivers and fiber cables. Key Features: Passive or active options: Passive DAC relies on the physical properties of copper and requires no additional power for signal conditioning. Active DAC contains integrated electronics to boost the signal for longer distances. Short reach: Typically supports distances up to 7 meters (23 feet), ideal for connections within racks or between adjacent racks. Cost-effective: Lower cost compared to active optical cables (AOC) or optical transceivers with fiber. Low power consumption: Particularly in passive versions, DACs consume minimal power. Plug-and-play: Simple deployment without complex configuration. Typical Applications: Server-to-switch connections within data centers. Switch-to-switch stacking and interconnects. Storage systems interconnects. High-performance computing (HPC) clusters.

Transceiver (Transmitter + Receiver) A transceiver is a device that integrates both a transmitter and a receiver into a single unit to send and receive data signals over a communication channel. In server, storage, and network environments, transceivers are typically used to convert electrical signals into optical signals (or vice versa) for high-speed data transmission across fiber optic or copper links. Key Features: Combines transmitting and receiving functions into one compact module. Supports various data rates (e.g., 1Gbps, 10Gbps, 25Gbps, 40Gbps, 100Gbps, 400Gbps, or higher). Available in multiple form factors such as SFP, SFP+, QSFP+, QSFP28, QSFP56, QSFP112, OSFP, CFP, etc. Can operate over copper (e.g., DAC cables) or fiber optic cables (e.g., with AOC or discrete fiber transceivers). Typical Applications: Network switches, routers, servers, and storage systems. Data center interconnects, enterprise networks, and telecommunications. Long-distance, high-speed data transmission over fiber optic links.
