Patch cable Synergy21 CAT6A S-STP 500 MHz RJ45 0.25 m outdoor UV- and water-resistant

Short Synergy21 CAT6A S-STP patch cable, 0.25 m, designed for outdoor use with UV- and water-resistant jacket. This cable supports frequencies up to 500 MHz and uses RJ45 terminations to connect switches, routers, patch panels and other networking equipment where shielded high-speed Ethernet links are required. The S-STP (screened shielded twisted pair) construction reduces electromagnetic interference and crosstalk, making it suitable for installations near electrical equipment or in congested cabling environments.

Advantages

The compact 0.25 m length minimises excess cable in patching areas and helps keep racks and outdoor enclosures tidy. S-STP shielding enhances signal integrity at high frequencies up to 500 MHz, while the outdoor-rated, UV- and water-resistant jacket provides mechanical protection and longevity in exposed environments. RJ45 connectors ensure compatibility with standard Ethernet ports and simplify installation without special tools beyond normal network termination equipment.

Suitable for

• Short interconnections between switches, routers and patch panels in outdoor or sheltered outdoor enclosures
• Shielded Ethernet runs where EMI reduction is required, such as near electrical panels or industrial equipment
• High-frequency Ethernet applications up to 500 MHz and Category 6A networks
• Patching within compact spaces where minimal cable slack is desired

When it may not be suitable

This 0.25 m patch cable is not intended for long-distance runs; use it only for short links inside cabinets or between closely spaced devices. If an unshielded cable is required for cost or compatibility reasons, a UTP cable would be more appropriate. Also, for indoor-only applications where outdoor resistance is unnecessary, a standard indoor-rated CAT6A cable may offer comparable electrical performance at lower cost.

Key specifications

• Cable category: Category 6A (CAT6A)
• Shielding: S-STP (shielded twisted pair with overall and individual pair screening)
• Frequency rating: up to 500 MHz
• Connector type: RJ45 on both ends
• Length: 0.25 m
• Jacket properties: UV-resistant and water-resistant for outdoor use
• Typical use: Patch cable for high-speed Ethernet and shielded installations

How to use

Insert RJ45 connectors into the Ethernet ports of the devices to be linked, ensuring secure clicks at both ends. Use the cable for short patching tasks inside outdoor cabinets, wall-mounted enclosures or on the exterior of buildings where a weather-resistant connection is required. Avoid tight bends beyond the manufacturer’s minimum bend radius and do not overload cable glands to maintain the jacket’s protective properties. Verify link speed and shield continuity through network testing equipment after installation.

What to consider before purchase

• Required length — 0.25 m is suitable only for short connections between nearby devices
• Need for shielding — choose S-STP when electromagnetic interference reduction is necessary
• Installation environment — confirm outdoor UV and water resistance is needed for exposed locations
• Compatibility with device Ethernet ports and space available in enclosures

Usage recommendations

Use this Synergy21 CAT6A S-STP 0.25 m patch cable for short, shielded outdoor interconnections. Test link integrity and grounding when integrating shielded cables into a wider network to ensure optimal performance and EMI mitigation.
