[ CABLE / ADAPTER RECORD // ANSI/TIA CATEGORY 8 / IEEE 25GBASE-T AND 40GBASE-T ]
Category 8 25G/40G Ethernet Patch Cable
Shielded 100-ohm four-pair copper terminated to 8P8C; designed for short data-center channel.
CLASSIFICATION: Network and fiber cables. Identify protocol, direction, pinout and exact cable revision before connection.
Interface and capability
| Standard / protocol | ANSI/TIA Category 8 / IEEE 25GBASE-T and 40GBASE-T. Connector appearance alone does not establish compatibility. |
|---|---|
| Endpoint / pinout | Shielded 100-ohm four-pair copper terminated to 8P8C; designed for short data-center channel. |
| Capability / limits | Cat8 channel reaches up to 30 m for 25/40GBASE-T; individual patch cord is not automatically a certified channel. |
| Certification / length | Standards define interface requirements, not every assembly’s performance. Certification, mode, current/power rating, direction and maximum length belong to the exact product/revision and complete channel; verify its manufacturer specification. Do not infer certification from connector shape or marketing terminology. |
Compatibility & handling
- Use compatible PHYs, complete shielded/bonded channel and proper termination. Marketing 40G label does not qualify host equipment.
- Inspect connector keying, latch, contact condition, shielding, jacket and model/revision marking. Stop if contacts are bent, loose, scorched, corroded or mismatched.
- Route without tension or sharp bends; follow product bend-radius, strain-relief, current and environmental limits. Test at the intended protocol and mode—physical fit is not a compatibility test.
