TP-LINK TL-SM321A-2

The linear distance that a cable covers, expressed with a length unit such as meters, centimeters or inches. It represents the total usable length of the cable for connecting devices.

The highest theoretical speed at which a device can send or receive information, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. It represents the upper bound of throughput under optimal conditions and is useful for comparing performance across devices and interfaces.

The general classification of a product, such as tablet, smartphone, router, or computer. It indicates the primary function or form factor that helps buyers quickly identify and compare similar items.

The pixel dimensions of a display or image, expressed as width by height (e.g., 1920x1080). It indicates how many pixels are used to render the visual content and is commonly used for monitors, TVs, smartphones, cameras, and digital images.

The type of fiber‑optic Ethernet cabling supported by the product, such as 1000BASE‑X, 10GBASE‑LR, or 40GBASE‑SR4. It indicates which standardized fiber media and transceiver combinations are compatible with the device.

The classification of optical fiber used in a network transceiver or cable, indicating whether it is single‑mode (SMF), multi‑mode (MMF), or a specific variant such as SM (Single‑Mode) or MM (Multi‑Mode). It may also include the core diameter specification (e.g., 9/125 µm). This attribute helps users identify compatibility with devices and understand signal propagation characteristics.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

A list of the physical or logical interfaces that a product can use to connect with other devices or components, such as USB, PCI Express, SATA, M.2, Ethernet, Thunderbolt, and similar standards.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The form of packaging used for a product, such as box, blister pack, bag, or pallet. It indicates how the item is contained and protected during shipping and storage.

The electrical power consumption or output of the product, expressed in watts (W). It indicates how much energy the device uses during operation or how much power it can deliver to connected equipment.

The number of times per second that a display updates its image, expressed in hertz (Hz). It indicates the smoothness and responsiveness of motion on the screen; higher rates generally provide a more fluid visual experience.

The range of relative humidity (expressed as a percentage) within which the storage device is designed to operate reliably. Values are given as a minimum–maximum interval such as "10 - 90 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

A list of environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.

The length of time for which the manufacturer guarantees that the product will be free from defects in materials and workmanship, typically expressed in years or months.
