  • Restricting Fixed IP Access to Switches

    Restricting Fixed IP Access to Switches

    You can configure Access Control to allow only specific users to access the switch and block the others. In this article, I'll walk you through the steps to configure access profiles and profiles rules for your Cisco switch. For example, you can restrict access to SSH. By default, there is no restriction on the user IP addresses that can access a device as long as a user enters the correct username and password. To configure the IP Limit feature, a device must be configured first.

  • Is an optical module a device or a material

    Is an optical module a device or a material

    An optical module is a small device that moves data using light. It changes electrical signals into light signals and back again. This helps data travel faster and farther than with copper cables. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. As an important part of fiber-optic communication, an optical module is a photoelectric converter which converts electrical signals into optical signals and vice versa. An optical module works at the physical layer of the OSI model and is one of the core components in the fiber communication. As an essential component of optical fiber communication, optical modules are optoelectronic devices that facilitate the conversion between optical and electrical signals during the transmission process.
