## Summary description

Synergy21 S216490 is a 0.25 m Cat6a networking cable with S/FTP (S‑STP) shielding and RJ-45 connectors on both ends. Designed for high-speed Ethernet links, it supports Cat6a performance and reduces electromagnetic interference with foil-braided shielding. Suitable for short patch connections between switches, routers, network cards and patch panels in office or data center environments.

## Long description

Synergy21 S216490 is a 0.25 m Cat6a S/FTP (S‑STP) networking cable with RJ‑45 connectors on both ends, designed for short patch connections in professional network environments. The cable supports Cat6a performance for high-speed Ethernet links and incorporates foil-braided shielding to reduce electromagnetic interference and crosstalk. Its compact length and robust RJ‑45 plugs make it suitable for interconnecting switches, routers, network interface cards and patch panels where space is limited.
Advantages
The S/FTP (foil‑shielded pairs with overall braided screen) construction offers enhanced protection against external interference while maintaining signal integrity at higher frequencies typical for Cat6a. The 0.25 m length minimizes excess cabling and improves airflow and cable management in dense rack or desktop setups. Shielded RJ‑45 connectors ensure a reliable mechanical and electrical connection, helping preserve link quality for Gigabit and 10 Gigabit Ethernet applications over short distances.
Suitable for
Short patch connections between switches and patch panels in server rooms and network cabinets
Direct connections from routers to switches or network cards where minimal cable slack is required
High-density network racks and structured cabling installations with limited space
Environments with potential electromagnetic interference requiring shielded cabling
Key specifications
Cable category: Cat6a suitable for 10 Gigabit Ethernet over short distances
Shielding: S/FTP (individually foil‑shielded pairs plus overall braided screen)
Connector type: RJ‑45 to RJ‑45, 8P8C
Length: 0.25 m
Color: Black
Typical use: Patch cable for network devices and patch panels
How to use
Insert each RJ‑45 connector into the corresponding network port until the latch clicks to ensure a secure connection. Use this 0.25 m cable for direct, short-distance links where minimal slack is desirable — for example between adjacent ports on a switch and a patch panel. Avoid sharp bends near the connectors and do not stretch the cable; maintain gentle curves to preserve shielding and conductor integrity. For best results in shielded installations, ensure proper grounding of connected hardware and cable screens as part of the overall network earthing strategy.
Usage recommendations
Choose this Synergy21 Cat6a S/FTP cable when you need reliable, shielded short‑reach connections in racks or desk-mounted equipment. For installations with significant electromagnetic noise or long cable runs, evaluate appropriate cable categories and grounding measures to match required performance and distance.
