With ethtool, we can also change settings like speed, duplexity, and toggling auto-negotiation. It takes the device name (like swp1) as an argument. See man ethtool(8) for details.

This guide introduces how to read optical module information when it is installed on a network card in a Linux system.
[pdf] Photovoltaic modules, or solar modules, are devices that gather energy from the sun and convert it into electrical power through the use of semiconductor-based cells. The concept of the module. The United Nations Climate Action report reveals fossil fuels to be the biggest culprit of global climate change with 75% greenhouse gas emissions.
[pdf] Optical interconnects operate on the fundamental principle that light can be modulated to carry information, which is then transmitted through a medium, such as optical fibers or waveguides, to a receiver that converts the light back into an electrical signal. In integrated circuits, optical interconnects refers to any system of transmitting signals from one part of an integrated circuit to another using light. Advanced Signal Integrity for High-Speed Digital Designs, S. Heck, John Wiley & Sons, 2009. Optical interconnects have negligible frequency dependent loss, low cross talk and high band width. Another important task, however, is enabling data center operators to scale quickly and reliably.
[pdf] There have been multiple variants of the electrical interface of optical modules that have been used over the years. The earliest forms of optical modules had an analog electrical interface. In the transmit direction, the optical module would directly drive the laser or LED with the analog signal coming from the front system card. In the receive direction, the module would directly drive the receive electrical interface with the o.
[pdf] A wedged plate beamsplitter splits a single input beam into multiple copies through successive reflections and refractions. These exiting beams are differentiated by either their optical power (non-polarizing) or polarization states (polarizing). It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications.
