4. Compatibilità
This RJ45 plug is specifically designed for use with Cat7 and Cat6A shielded cables.
- Tipi di cavi supportati: Cat7, Cat6A shielded Ethernet cables.
- Spessore del filo: Each individual wire within the cable must have an outer diameter (OD) of Da 1.35 mm a 1.45 mm (AWG: 23).
- Incompatible Cable Types: This plug is non compatibile with Cat8, Cat6, Cat5e, or Cat5 cable versions. Using incompatible cable types may result in improper wire seating and connection failures.

5. Configurazione e installazione
To properly terminate an Ethernet cable with the VCELINK Cat7 Cat6A Pass Through RJ45 Plug, follow these steps. A professional RJ45 crimping tool designed for pass-through plugs is required.
Strumenti necessari:
- RJ45 Crimping Tool (Pass-Through type recommended)
- Cable Stripper
- Tronchesi

Fasi di installazione:
- Insert Cable Cap: Slide the cable cap onto the Ethernet cable.
- Strip Cable Jacket: Use a cable stripper to remove approximately 2-3 cm of the outer jacket from the Ethernet cable.
- Remove Shielding (if applicable): For shielded cables, carefully remove any foil or braid shielding, leaving the drain wire intact.
- Districare e disporre i fili: Untwist the individual wire pairs and arrange them according to the T568B or T568A wiring standard (T568B is most common). Ensure the wires are straight and parallel.
- Fili di rifinitura: Trim the wires to a length of approximately 1.2-1.5 cm from the edge of the jacket. Ensure all wires are of equal length.
- Insert Wires into Plug: Carefully insert the arranged wires into the RJ45 plug, ensuring they pass completely through the front of the plug. Verify the correct wire sequence through the transparent plug body.
- Crimpare la spina: Insert the RJ45 plug into the crimping tool. Squeeze the handles firmly until the connector is fully crimped. The crimping tool will cut off the excess wires protruding from the front of the plug.
- Secure Bend Protector: Slide the bend protector over the crimped plug until it clicks into place, providing strain relief and protection.
- Prova di connessione: Use an Ethernet cable tester to verify proper continuity and wiring sequence.

6. Istruzioni per l'uso
Once the RJ45 plug is correctly terminated onto your Cat7 or Cat6A Ethernet cable, it is ready for use.
- Connessione: Insert the crimped RJ45 plug into any compatible RJ45 port on devices such as routers, switches, modems, computers, or other network equipment.
- Vestibilità sicura: Ensure the plug clicks securely into place. The latch on the plug should engage with the port to prevent accidental disconnection.
- Disconnessione: To disconnect, gently press down on the latch of the RJ45 plug and pull it straight out from the port. Avoid pulling the cable directly without disengaging the latch, as this can damage the plug or the port.

7. Manutenzione
The VCELINK RJ45 plugs are designed for durability and require minimal maintenance.
- Mantenere pulito: Ensure the contact pins of the RJ45 plug are free from dust and debris. Use compressed air or a soft, dry cloth if cleaning is necessary.
- Evitare danni fisici: Do not bend the cable sharply near the connector. Avoid stepping on or placing heavy objects on the cable or connector.
- Conservazione corretta: When not in use, store cables with terminated plugs in a clean, dry environment to prevent damage to the connectors.
8. Risoluzione Dei Problemi
If you encounter issues with your network connection after installing the RJ45 plugs, consider the following troubleshooting steps:
- Nessuna connessione di rete:
- Verify that the RJ45 plug is fully inserted into the port and the latch is engaged.
- Check the wire sequence (T568B or T568A) on both ends of the cable using a cable tester. Incorrect wiring is a common cause of connection failure.
- Ensure all 8 wires are making proper contact within the plug. The pass-through design allows for visual inspection.
- Confirm that the cable type (Cat7/Cat6A) and wire thickness (1.35-1.45mm OD) are compatible with the plug.
- Test the cable with a known working device or a different cable tester.
- Bassa velocità di rete:
- Ensure both ends of the cable are terminated correctly for Cat7/Cat6A standards.
- Check that all network devices (router, switch, network card) support 10 Gigabit Ethernet speeds.
- Inspect the cable for any damage or kinks that could degrade signal quality.
- Connessione intermittente:
- Re-crimp the plugs if there's any doubt about the connection integrity.
- Ensure the cable is not subjected to excessive bending or strain.
- Verify that the shielded design is properly grounded if applicable to your setup, to prevent external interference.
