UGREEN 20158 0.5m Cat 6 U/UTP Ethernet Cable
UGREEN 20158 0.5m Cat 6 Ethernet Cable
Overview
UGREEN 20158 is a 0.5 m black Cat 6 U/UTP Ethernet patch cable for linking two compatible RJ45 ports. It is specified for data rates up to 1000Mbps and bandwidth up to 250MHz, with four unshielded twisted pairs, 26AWG copper-clad aluminium (CCA), a PVC outer jacket and moulded RJ45 connectors. The 0.5 m reach is suited to nearby ports in a compact desk, rack or media setup.

Key features
Gigabit-class listing
Rated for Ethernet data rates up to 1000Mbps when the complete network path uses compatible Gigabit ports and equipment.
250MHz Cat 6 bandwidth
Designed for Cat 6 network transmission with four twisted pairs and an internal cross-divider that helps manage pair separation and crosstalk.
26AWG CCA
This NW102 model uses 26AWG copper-clad aluminium (CCA). It is intended as a flexible data patch lead. Do not treat it as interchangeable with the pure-copper NW101 range, and do not assume PoE, permanent-building or outdoor approval unless the installation standard and jacket marking are verified.
0.5 m planned reach
A fixed 0.5 m cable length lets you choose the run before installation and avoid excess slack or an over-stretched connector.
A stable wired network path

A wired connection can reduce the variability caused by wireless distance, walls and radio congestion, but the cable is only one part of the network. The router, switch, wall cabling, network adapter, device settings and internet plan all contribute to the result.
The U/UTP construction uses twisting to control crosstalk without an overall shield. Keep the cable away from mains cables, transformers, motors and other strong interference sources where a practical alternate route exists.

Use scenarios
Router or switch patching
Connect nearby network equipment or bridge a router/switch to a wall jack using the 0.5 m reach.
Desktop and workstation
Create a wired link for a desktop PC, an Ethernet-equipped laptop, a dock with RJ45 or a network printer.
TV and gaming
Connect a smart TV, streaming player, PlayStation or Xbox that provides a standard RJ45 LAN port for downloads, streaming and online use.
NAS and local devices
Link compatible NAS units, access points, VoIP equipment and other RJ45 network devices, subject to their port and power requirements.
Setup and usability guidance
- Measure first: include corners, furniture and a small service loop; do not stretch a 0.5 m cable between ports.
- Check both sockets: each endpoint must have a standard RJ45 Ethernet port or a suitable Ethernet adapter.
- Insert straight: align the locking tab, push until seated and avoid sideways pressure on the port.
- Verify the link: confirm the port LEDs or operating-system network status, then test local and internet performance separately.
- Troubleshoot simply: reseat both ends, test known-good ports and bypass couplers or wall links before blaming the cable.

Compatible devices and systems
Compatibility depends on a standard RJ45 Ethernet interface—not on a specific brand or operating system.
Network equipment
Routers, broadband gateways with LAN ports, Ethernet switches, patch panels, wall outlets and compatible wireless access points.
Computers and storage
Desktop PCs, servers, NAS units and laptops that have an RJ45 port or use a compatible USB/USB-C Ethernet adapter or dock.
Home entertainment
Smart TVs, streaming boxes, Blu-ray players, PlayStation and Xbox consoles with RJ45 network ports.
Operating systems
No cable driver is required. Windows, macOS, Linux, ChromeOS and console/TV systems use their own Ethernet hardware, drivers and network settings.
What this product does
- Provides one passive, wired RJ45-to-RJ45 Ethernet connection over 0.5 m.
- Supports the listed Cat 6 maximum of 1000Mbps and 250MHz when the complete network path can negotiate that mode.
- Uses four twisted pairs and 26AWG copper-clad aluminium (CCA) inside a flexible black patch-cable jacket.
- Works without software, external power or a separate cable driver.
What this product does not do
- It does not create Wi-Fi, extend wireless coverage, assign IP addresses or replace a router, modem, switch or Ethernet adapter.
- It does not connect directly to USB-A, USB-C, HDMI, DisplayPort or smaller telephone-style RJ11 sockets.
- It does not make a 100Mbps port, slow device or internet plan run at 1Gbps.
- It is not advertised here as a 2.5GbE, 5GbE or 10GbE cable; select and verify equipment for those speeds separately.
- It is not automatically approved for outdoor, wet, direct-burial, plenum, riser, in-wall or PoE installation.
What to do
Match SKU
Choose UGREEN 20158 when you need the documented 0.5 m length and 26AWG CCA construction.
Leave gentle slack
Route with broad curves and a small service loop so moving a device does not pull on the locking tab or network socket.
Test the whole path
Check negotiated link speed and transfer performance on the local network before diagnosing the internet service.
Use the right adapter
For USB-only computers, choose an Ethernet adapter that supports the desired speed and the device’s USB/USB-C port.
What not to do
Do not force the plug
RJ45 is wider than a telephone plug and entirely different from USB. Stop if the connector does not align easily.
Do not crush or kink
Avoid doors, chair wheels, sharp bends, staples, tight cable ties and furniture pressure that can deform the twisted pairs.
Do not pull by the cable
Release the locking tab and hold the moulded plug when disconnecting; do not yank the jacket or twist the port.
Do not assume installation ratings
Confirm PoE current, fire/jacket class, outdoor exposure and local electrical/building rules before any powered or concealed route.
Warnings and limitations
Speed is end-to-end: 1Gbps is a supported maximum. The slowest port, cable segment, coupler, wall run, network setting or service becomes the practical limit.
Unshielded construction: U/UTP is intended for ordinary network routes. Increase separation from mains wiring and strong electrical-noise sources where possible.
PoE and building use: Cat 6 category alone is not proof of PoE class, in-wall fire rating or outdoor suitability. Verify the complete installation specification before use.
Physical condition: Keep connectors dry, disconnect damaged cable, and replace it if the latch, jacket or plug housing is cracked, crushed or exposed.

Product-specific FAQ
What is UGREEN 20158 designed to connect?
It creates one wired Ethernet link between two standard RJ45 network ports—for example a router and switch, a computer and wall outlet, or a console and router. It is a patch cable, not a router, modem or network adapter.
What length is this model?
UGREEN 20158 is the 0.5 m version. Measure the complete route, include gentle bends and leave a small service loop so neither RJ45 socket is held under tension.
What network speed does it support?
The listing specifies up to 1000Mbps (1Gbps) and up to 250MHz. Real throughput is limited by the slowest router, switch, network adapter, device, cable segment and internet service in the complete path.
Can it make my internet faster?
No cable can exceed the speed available from the internet plan or connected equipment. It can provide a stable wired link when every part of the network supports the intended speed.
Is this a shielded Ethernet cable?
No. It is identified as Cat 6 U/UTP: the four twisted pairs have no overall cable shield. Route it away from strong electrical-noise sources and power equipment where practical.
What conductor material is used in SKU 20158?
This listing is documented with 26AWG copper-clad aluminium (CCA). Similar-looking UGREEN Cat 6 models can use a different conductor or gauge, so match the SKU rather than assuming every length belongs to the same construction.
Will it work with a laptop that has only USB-C?
Not directly. The cable has RJ45 male connectors. A laptop without an RJ45 Ethernet port needs a compatible USB-C or USB Ethernet adapter or dock, purchased separately.
Can I use it for PS5, Xbox or a smart TV?
Yes, when the console, television or media device has a standard RJ45 LAN port. The device and network settings determine the negotiated speed and online performance.
Can I use it for Power over Ethernet (PoE)?
Do not infer PoE suitability from Cat 6 alone. For a powered camera, access point or phone, confirm the cable construction, PoE class, current requirement, installation length and local rules with the equipment documentation before use.
Can I install it outdoors or permanently inside a wall?
Do not assume outdoor, UV, moisture, plenum, riser or in-wall approval. Use this patch lead in dry indoor setups unless the jacket markings and local installation rules explicitly approve the intended fixed route.
What comes in the package?
The core package is 1 × UGREEN 20158 0.5 m Cat 6 RJ45 Ethernet patch cable. Routers, switches, adapters, couplers, wall plates and powered network equipment are separate.
