What are the most important connectivity standards to follow for a wired network?

1 Ethernet Standards

Ethernet is the most common protocol for wired networks. It defines how data is transmitted and received over cables and devices. There are different versions of Ethernet, such as Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet, that offer different speeds and features. Each version has a specific cable type and connector that supports it. For example, Fast Ethernet uses Category 5 (Cat 5) cables and RJ-45 connectors, while 10 Gigabit Ethernet uses Category 6a (Cat 6a) cables and RJ-45 or SFP+ connectors. You should choose the Ethernet standard that meets your network's bandwidth and distance requirements.

2 Cable Categories

Cable categories are another important standard to follow for a wired network. They indicate the quality and performance of the cable, such as its maximum data rate, frequency, and length. Higher cable categories can support higher Ethernet standards, but they are also more expensive and less flexible. The most common cable categories are Cat 5, Cat 5e, Cat 6, and Cat 6a. You should use the cable category that matches your Ethernet standard and your network's layout and design.

3 Connector Types

Connector types are the physical interfaces that connect the cables to the devices. They vary in shape, size, and functionality. The most common connector types for wired networks are RJ-45, SFP, and SFP+. RJ-45 is the standard connector for most Ethernet cables and devices, such as switches and routers. SFP and SFP+ are smaller connectors that are used for fiber optic cables and devices, such as 10 Gigabit Ethernet switches and routers. You should use the connector type that is compatible with your cable type and your device type.

4 Crossover and Straight-Through Cables

Crossover and straight-through cables are two types of Ethernet cables that have different wiring configurations. Crossover cables have the transmit and receive wires swapped at one end, while straight-through cables have the same wiring at both ends. Crossover cables are used to connect devices of the same type, such as two computers or two switches. Straight-through cables are used to connect devices of different types, such as a computer and a switch or a switch and a router. You should use the correct cable type for your network's topology and device connections.

5 Power over Ethernet

Power over Ethernet (PoE) is a standard that allows devices to receive both data and power over the same Ethernet cable. This eliminates the need for separate power cords and outlets, which can save space, cost, and energy. PoE can be used for devices such as IP phones, wireless access points, and security cameras. To use PoE, you need a PoE-enabled device, a PoE-enabled switch, and a PoE-compatible cable. You should use PoE if you want to simplify your network's installation and management.

6 Cable Management

Cable management is the practice of organizing and securing the cables in your network. It helps to improve the appearance, safety, and performance of your network. Cable management can involve using cable ties, labels, trays, racks, and panels to keep the cables neat and tidy. You should use cable management if you want to avoid cable clutter, damage, interference, and confusion.
