Copper Cable Solutions for Offices, Networks and Data Centers
Reliable network performance depends on choosing the right cable for the job. Although fibre optic cable carries data over long distances and supports high-capacity backbone links, copper Ethernet cable remains a practical choice for connecting computers, IP cameras, wireless access points, VoIP phones and other devices across a local network.
Founded in 2006 and headquartered in Shenzhen, OYI International Ltd. supplies connectivity products to customers in markets around the world. Our product range includes fibre optic solutions as well as copper cabling for the connections that bring a network to individual workstations, devices and equipment racks.
Copper Ethernet Cable for Everyday Network Demands
Copper Ethernet cable can carry data and, when used with compatible equipment, power over the same cable through Power over Ethernet (PoE). This makes it useful for installations such as office LANs, IP surveillance systems and wireless access points, where a separate power connection may be inconvenient.
Cable performance depends on more than the category printed on the jacket. Conductor quality, pair construction, shielding, jacket material and installation all affect how reliably a link performs. Selecting a cable to suit the application helps reduce avoidable problems during installation and operation.
Ethernet Cable Categories at a Glance
The main difference between Cat5e, Cat6, Cat6A and Cat7 is the performance each category is designed to support. The appropriate choice depends on the required data rate, link length, installation environment and plans for future upgrades.

Shielding and Jacket Options
Copper cables are also available in different shielding constructions. UTP cable has no overall metallic shielding, while foil- or braid-shielded designs can help control electromagnetic interference in electrically noisy environments. Shielded cable should be selected and installed as part of a properly grounded system.
The outer jacket should match the installation environment. PVC is commonly used for general indoor cabling; LSZH materials are chosen where low smoke and halogen-free performance is required; and outdoor installations may call for a suitable UV-resistant jacket. Always confirm the required fire rating and local code before specifying a cable.
Where Copper Cable Is Used
Offices and Commercial Buildings
Structured copper cabling connects workstations, printers, phones and wireless access points in offices, schools, hotels and other commercial buildings.
Data Centers
Within equipment rooms, copper links connect servers, switches and patch panels. Cat6A and Cat7 may be suitable for higher-bandwidth links, depending on the required distance and network design.
Security and Surveillance
PoE-compatible Ethernet cabling allows IP cameras and other devices to receive data and power over one connection, helping simplify installation.
Industrial and Smart Building Systems
Where automation equipment, access control and building-management systems operate near sources of electrical interference, the cable construction and shielding should be chosen with the site conditions in mind.
How to Choose the Right Copper Cable
1. Start with bandwidth and distance. Cat5e may be sufficient for basic connectivity. Cat6 supports many enterprise LAN applications, while Cat6A is a common choice for 10 Gbps links up to 100 m. Cat8 is intended for much shorter, high-speed data-center links.
2. Check the conductor material. Solid bare copper is generally preferred for permanent building cabling. Copper-clad aluminium (CCA) has higher resistance and may not meet the requirements of standards-compliant structured cabling or PoE installations.
3. Allow for PoE loads. Higher-power PoE applications can increase cable temperature, especially in tightly packed bundles. Conductor size, cable category, bundle size and installation conditions should all be considered.
4. Match shielding to the environment. UTP is often suitable for typical office spaces. Shielded cable may be appropriate near machinery or other strong sources of electromagnetic interference, provided it is installed and grounded correctly.
5. Choose a suitable jacket. Consider whether the cable will be installed indoors, in a plenum or public space, or outdoors. Confirm the applicable fire, smoke and environmental requirements before ordering.
6. Keep within channel limits. A standard Ethernet channel is generally limited to 100 m, including the permanent link and patch cords. A typical design allows up to 90 m for the permanent link and 10 m for patch cords.
Why Work with OYI?
For network projects, product consistency and clear technical communication matter just as much as the cable itself. OYI supplies connectivity products for customers across international markets, with a focus on helping buyers identify suitable solutions for their applications.
Our cables use copper conductors available in 23, 24, 26 and 28 AWG, and are supported by UL, ETL, RoHS and CE certifications. Together with our fibre optic range, they support projects that combine fibre backbones with copper connections at the network edge.
Free OEM service is available. Cables are packed 305 m per roll, with a minimum order of 50 rolls and a lead time of 25 working days. Please share your required category, conductor, shielding and jacket, and our team will prepare a matching quotation.
Installation Tips for Better Results
· Plan the cable route. Keep copper cabling appropriately separated from power cables and other sources of interference, following local standards and installation guidance.
· Respect bend radius and pulling limits. Avoid sharp bends, crushing or excessive pulling force. Follow the cable manufacturer's specifications.
· Terminate carefully. Keep pair untwist close to the minimum required at the connector and use compatible components. Poor termination can undermine cable performance.
· Test every link. Use a suitable cable certifier when the project requires performance certification. Keep test records for commissioning and future maintenance.
Frequently Asked Questions
What is the maximum length of an Ethernet cable? A standard Ethernet channel is generally limited to 100 m, including patch cords. The permanent link is typically designed for up to 90 m.
Can Cat6 support 10 Gigabit Ethernet? Cat6 can support 10 Gigabit Ethernet over shorter distances, commonly up to around 55 m under suitable conditions. For 10 Gbps over a full 100 m channel, Cat6A is the usual choice.
Why is bare copper generally preferred over CCA? CCA has higher electrical resistance than bare copper, which can increase voltage drop and heating, particularly in PoE applications. Check the project specifications and relevant standards when selecting conductor material.
Do I need shielded Ethernet cable? Not necessarily. UTP is suitable for many office installations. Shielded cable can help in electrically noisy environments, but it must be installed with appropriate grounding and compatible components.
What is the difference between PVC and LSZH jackets? PVC is widely used for general cabling. LSZH materials are designed to emit less smoke and no halogen gases under specified fire conditions, and may be required by local codes in certain buildings.
Is Cat8 necessary for an office network? Usually not. Cat8 is designed for short, high-speed links, mainly in data-center environments. Choose the category based on actual bandwidth and distance requirements.
