Cellular

refers to the wireless communication method that utilizes a network of cell sites, each covering a specific area known as a cell.

Satellite

uses satellites orbiting the Earth to relay data, voice, and video across long distances, including remote and rural areas where other forms of connectivity might be unavailable.

802.3 Standards

Set of standards, also known as Ethernet, defines the protocols for wired LAN (Local Area Network) technology, covering aspects like frame formats and physical layer specifications

Single Mode Fiber

designed for long-distance communication, using a single strand of glass fiber with a small diameter that allows only one mode of light to propagate.

Multimode Fiber

A type of fiber optic cable that carries multiple light signals on a single strand.

Direct Attach Copper (DAC)

Cost-effective cables for short-range networking connections.

Twinaxial Cable

A variant of coaxial cables, which features two inner conductors instead of one and is used for very-short-range high-speed signals.

Coaxial/RG-6 Cable

A type of electrical cable consisting of a central conductor, insulating layer, metallic shield, and plastic jacket, used for transmitting television, satellite, and broadband internet signals.

Cable Speeds

Cable speeds vary by type, impacting network performance; Ethernet cables like Cat 5, 5e, 6, and 6a support speeds from 100 Mbps to 10 Gbps over varying distances.

Plenum Rating

Indicates fire resistance and low smoke emission of cables.

Non-plenum cables

Less expensive, toxic fumes when burned.

Transceivers: Protocol

ensures reliable data transmission, minimizes errors, and supports the desired network speed and performance.

Ethernet

widely used networking technology that governs how data is transmiƩed over LANs, supporting a variety of speeds ranging from 10 Mbps to 100 Gbps.

Fibre Channel (FC)

high-speed network technology primarily used for transmitting data between computer devices at data rates of up to 16 Gbps (and higher) in storage area networks (SANs).

Small Form Factor Pluggable (SFP)

compact, hot-pluggable network interface module used for both telecommunication and data communications applications.

Enhanced form-factor pluggable (SFP+)

an upgraded version of the SFP that supports data rates up to 10 Gbps.

It is used for high-speed network connections on network switches, routers, and other networking equipment.
