What’s a LAN? (LAN Definition)

An introduction to the essential concepts of a LAN

lan cable definition

Local Area Network or LAN for short is a network or group of computers and associated devices that share a common communications line or wireless link in a limited area, such as in an office building, school or house. The function of the LAN is to enable sharing of data and resources like files, printers, games, applications, email or internet access.

LANs are usually built to enable the sharing of resources and services like files, printers, games, applications, email, or internet access.

Technologies Commonly Associated with LAN

In this modern age, LANs either used Wi-Fi or Ethernet for connecting two or more devices together.

Wi-Fi LAN and Broadband Routers

The Wi-Fi LAN can operate multiple wireless access points whenever the device detects the signal range of the Wi-Fi. On the other hand, the LAN we find at home or the wireless broadband routers perform the functions of an access point.

Ethernet LAN Components

The typical Ethernet LAN has hubsswitches, or routers that individual devices connect to through LAN cables.

Because of their low-cost and speed requirements, Ethernet and Wi-Fi are preferred in most businesses and houses, but a LAN with fiber connections can also be used.

Benefits of LAN

Since sharing is a major role of a local area network, it’s clear that this type of network means faster communication. Not only can files and other data be shared much more quickly if they stay within the local network instead of reaching the internet first, but point-to-point communication can be set up for even faster internal communication.

Are LAN and Ethernet the Same?

Can you connect an LAN Cable to an Ethernet port?

According to IEEE, Ethernet is a technology for wiring or cabling configurations in data networks which connects software and/or hardware with each other. This connection takes place through LAN cables, which is why Ethernet is sometimes referred to as LAN technology.


Computers, laptops and consumer electronics usually have an Ethernet port for connecting the device to a wired network. A LAN port is an RJ-45 Ethernet socket where all client machines, servers and network devices on the local network are cabled to.

OTSCABLE LAN Cable Manufacturing Process

With our company’s expertise in cable production, our in-house cable manufacturing process produces the best premium LAN Cables for network and communication cabling

Step #1 Wire Diameter Reduction Through A Series of Wire Drawing Processes

Wire Drawing Processes

1st Wire Draw

The first step in manufacturing LAN cables is wire drawing. Wire drawing is a process in which the wire is drawn through a die so as to reduce its diameter and increase the length. As this happens, its volume remains the same.

The dies are flooded with lubricant which also serves as a coolant, increasing the life of the dies and keeping the copper wire from overheating.

The result of this process is a 5000 ft of coil of 10, 12, or 14 AWG copper wire.

2nd Wire Draw

The copper wire produced in the first draw will then be transferred to an insulating area of the plant where a second wire draw will be done followed by annealing, before the application of insulation to the copper wire.

In the second wire draw, the size of the wire is reduced to 19, 22, 24, 26AWG or to any size needed.

Step #2 Softening the Wire Through Annealing

From its brittle state after drawing, the wire needs to be annealed to make it ductile. Annealing is simply the process of heating the copper to a certain temperature then slowly cooling it.

At this stage, the wire submerged in water is heated up to 1000 deg F for just a moment before taking it out of the water. Submerging it in water prevents oxidation and corrosion of the metal.

Step #3 Wire Extrusion and Insulation

The next step requires the wire to be passed through an extruder where either a single or double coating of plastic is applied. High-density polyethylene pellets are fed into the extruder, heated and mets.

Step #4 Wire Diameter and Insulation Testing

Before the reels move to the next manufacturing operation, wire and insulation diameter are measured, and the wire is tested for electrical properties as capacitance and resistance.

Step #5 Wire Twisting and Stranding

In this step, the insulated wires are twisted into wire pairs. Each pair has a unique twist length to avoid crosstalk and interference.

The wires will now be tested for electrical defects such as crosses, shorts, and opens.

Step #6 Cabling

At this stage, the wires that came out from the stranding process are grouped together forming a multi-unit cable core. The units are also twisted together on a rotating core truck to help control electrical interference and provide flexibility.

Step #7 Jacketing

At jacketing, several operations such as gel-filling, armoring, jacketing, and printing are performed to produce the finished cable.

Gel-filling and Armoring

The cable core is heated ensuring that the filling compound penetrates possible voids. A filling compound is added into the heated core in the filling chambers. Then finally, a plastic core is wrapped around the cable.

Metal Sheathing

Depending on the cable design, a protective metal sheathing of either aluminum or aluminum and steel combined may be added during this manufacturing step. The aluminum acts as a grounding path for high-voltage surges that may be caused by lightning strikes and other eventualities in aerial cables, while steel adds mechanical protection for buried cable against pests such as rats and gophers.

Extrusion of Outer Cable Jacket

The outer cable jacket is extruded in the next step. It is usually made from low-density polyethylene, black in color and resistant to ultraviolet light in case it is exposed to sunlight. This rugged plastic is the final protection for the enclosed cable against the environmental conditions underground or when strung to utility poles.

Cooling and Finishing Touches

The jacketed cable then passes through a temperature- controlled water trough, which cools the jacket. The cable is dried, and the top layer of the jacket is heated slightly so that printer markings can be imprinted on it. Because of the heating, the markings are stamped into the jacket itself and will last the life of the cable.

Step #8 Cables Tested Before Shipping

Upon exiting the jacketing operation, the finished cable is wound onto metal or wooden reels and then transported to the final test facility.

Physical Inspection of the LAN Cable

An inspector checks for proper placement of units, subunits, and spare pairs within the cable.

Electrical Test

Electrical tests include a ring-out of all conductors for continuity, and a core-to-sheath test. The core-to-sheath test measures minimum voltage requirements between the cable core and the metal sheath; this helps ensure that high-voltage surges, such as lightning strikes, cannot reach the conductors. A high-voltage test is also performed, and all conductors are checked for electrical integrity. Random tests are performed for mutual capacitance, unbalance, and resistance.


Preparing the cable for shipment may include sealing the cable end with a steel or plastic cap, and testing air-core cables for integrity. Such cables are equipped with valves so that dry, pressurized air can be pumped into them to protect them from moisture.

Quality Control

“If a thing’s worth doing, it’s worth doing well,” as quoted by a Chinese proverb.

OTSCABLE not only assures the best quality LAN Cables are delivered into the market, but also upholds an environmental responsibility of disposing raw materials, in-process products and end-products which can potentially harm the environment.

OTSCABLE follows a round of quality checks throughout the production process from raw material acceptance to production and to end-products processing prior to shipping.

Raw-Material Quality Control (RMQC)

High-quality raw material is paramount in delivering standard-wise end-products. Upon delivery of the raw materials (copper wires, etc), they go through IDC inspection that determines whether they pass or fail. Failure to meet specific standards will automatically reject the raw materials.

Production Quality Control (PQC)

Mass producing LAN cables from the raw materials stored in the warehouse is carried out in the production area.

A certain procedure for testing the cables would be by randomly picking a 90-m cable and by fluke testing it for on-contact to contact voltage, continuity detection and open jaw current detection. Also, the connectors are checked if they conform with T568B standard.

OTSCABLE also carries out a series of quality checks in the production area whether daily, weekly, monthly or yearly. This is to check if certain measures should be done in their machines or manufacturing process should be improved or fixed to meet safety standards for both the process and their employees.

In-Process Quality Control (IPQC) and Unfinished Product Quality Control (uPQC)

These are checks that are carried out during mass production is  completed. In-process materials are tested for identity, strength, quality and purity as appropriate and approved or rejected by the quality control unit during the production process.

Quality Control Before Packing and Final Quality Control

Before LAN Cables are packed or boxed, the QC unit checks the products for possible cracks, breaks and cable connectivity. The cables are also physically inspected and tested (electrical tests are ran).

LAN Cable FAQs

How can I choose the right ethernet cable?

First, determine the speed of your internet connection. An old ethernet cable cannot be able to sustain you if you have an internet running on a gigabit. But if you have a slower connection, like 10 or 20 megabits per second, you can get Cat 5.

Next, consider the speed you need for your network. If you happen to move files frequently or you video stream most of the time, a high-bandwidth is required so a better Ethernet cable can be better.

Finally, consider your router. A Cat 6 or newer is usually used as routers rarely support more than gigabit Ethernet, but some may use Cat 5e.

Does Ethernet use all 8 wires?

LAN cables/Ethernet cables have eight wires (four pairs) but only four (two pairs) of these wires are actually used, under 10BaseT and 100BaseT standards (10 Mbps and 100 Mbps, respectively) . One pair is used for transmitting data and the other pair is used for receiving data.

What is 10GBASE-T and Why Is This Technology So Important?

10GBASE-T is a type of Ethernet signaling that provides speeds that go beyond 1 Gb per second for a hundred meters. This capability can be able to provide about 10G on the desktop for data centers. Increase bandwidth opens the door for developers to grow essential applications.

How To Wire and Crimp RJ45 Connector for T568B Ethernet Standard

T568A and T568B are the two colour codes used for wiring eight-position modular plugs. At OTSCABLE, we typically follow these two types of color coding. Both are allowed under the ANSI/TIA/EIA wiring standards. The difference between these standards is that the orange and green pairs are just interchanged.
