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 maximum power level at which a device can transmit radio signals, expressed in the appropriate unit such as decibels relative to one milliwatt (dBm) or milliwatts (mW). It indicates the strength of the transmitted signal and is used to assess coverage range and regulatory compliance.
