RJ45 Splitter (1×8P8C to 2×8P8C) Lexi-NET ROZDV8/8 – telephone connection adapter

Lexi-NET ROZDV8/8 is an RJ45 splitter designed to convert one 8P8C (RJ45) telephone line into two 8P8C outputs for basic voice and telephone installations. The passive adapter provides a direct physical split of the incoming RJ45 connection so two telephony devices can share a single wall or patch panel outlet without active circuitry. Its compact design suits small office or home environments where Cat3 telephone wiring or single-line voice connections need simple duplication.

Advantages

The splitter offers a straightforward, low-cost method to duplicate a single telephone line to two devices while maintaining the original wiring polarity and pin mapping for voice signals. Because it is passive, installation requires no power, programming or configuration and it is compatible with standard 8P8C connectors used for telephony. The small footprint enables discreet placement behind furniture, inside outlet boxes or within communication enclosures.

Suitable for

• Duplicating a single RJ45 telephone line to two handsets
• Small office or home voice installations using Cat3 or legacy telephone cabling
• Temporary or low-cost line sharing where no active line splitting is required

Key specifications

• Connector input: 1 × 8P8C (RJ45)
• Connector outputs: 2 × 8P8C (RJ45)
• Function: Passive split for analog voice/telephone signals
• Cabling compatibility: Cat3 and standard telephone-grade twisted pair wiring
• Power requirements: None (passive device)
• Form factor: Compact inline adapter for wall or panel connections

How to use

Plug the incoming RJ45 telephone lead into the single 8P8C input of the splitter, then connect the two destination telephone devices to the splitter outputs using standard RJ45 patch cords. Ensure connectors are seated fully and that cables are not carrying data or network signals intended for Ethernet devices. This adapter is intended for voice-grade wiring and does not provide signal amplification or protection. Test each handset for dial tone after installation to confirm proper continuity.

Usage recommendations

Use this splitter only for analog telephone or voice lines and avoid connecting it to active Ethernet or data services. For installations requiring power, signal conditioning, multiple extensions, or digital line management, choose an active splitter or telephony distribution solution. Keep connections dry and avoid sharp bends in cables to maintain reliable voice quality.
