Cabo S-Impuls 1 m — RJ45 (8/4) para RJ11 (6/4) cabo adaptador de telefone

S-Impuls 1 m adapter cable with RJ45 (8/4) connector on one end and RJ11 (6/4) on the other provides a simple wired conversion between standard modular telephone connectors. The cable is intended for telephone and low-speed data line use, enabling connection of desk phones, analog modems, PBX extensions and other legacy devices that require converting between RJ45 and RJ11 pinouts. A compact 1 metre length makes the cable convenient for desktop setups and short patch runs without excess cable bulk.

Advantages

The adapter cable offers a reliable mechanical connection and straightforward compatibility with devices that use either RJ45 (8/4) or RJ11 (6/4) modular plugs. Its short length reduces signal attenuation and clutter in office or home environments while preserving the necessary conductors for voice and low-speed data transmission. The cable is plug-and-play and does not require configuration, making it practical for rapid deployment in PBX and telephone line maintenance tasks.

Suitable for

• Connecting desktop telephones to PBX extension ports
• Linking analog modems to telephone wall jacks
• Adapting legacy network or telephony equipment with mismatched connectors
• Short patch runs at workstations or communication cabinets

Key specifications

• Cable length: 1 metre
• Connector A: RJ45 modular plug (8-position, 4-conductor wiring)
• Connector B: RJ11 modular plug (6-position, 4-conductor wiring)
• Intended signals: voice and low-speed data (analogue telephone lines, modem connections, PBX extensions)
• Construction: flexible insulated conductors in a single jacket suitable for indoor desktop use

How to use

Insert the RJ45 end into the device or wall jack equipped for an 8-position plug and insert the RJ11 end into the telephone, modem or PBX handset port requiring a 6-position plug. Ensure connectors are fully seated to establish reliable contact. The cable performs passive pinout conversion and requires no power or software. Verify correct operation by testing voice audio or modem handshake as applicable after connection.

Recommendations

Use this 1 m adapter for short, indoor connections where correct pin alignment is required; avoid installing the cable in environments exposed to moisture or mechanical strain. For longer runs or high-speed data applications, choose cabling and converters rated for those requirements.
