Network splitter LechPol RJ45 1-to-2 (model TEL0023-2) for Ethernet/telephone connections

LechPol RJ45 1-to-2 splitter (model TEL0023-2) is a passive adapter that divides a single RJ45 port into two RJ45 connections. Intended for basic Ethernet and telephone wiring scenarios, the adapter provides a compact, plug-and-play way to connect two devices to one network line where additional ports or separate cabling are not available. The splitter is suitable for short-distance data and voice setups, temporary expansions, or simple home and office wiring adjustments.

Advantages

The splitter offers a low-cost, passive solution that requires no power or configuration. Its compact form factor makes it easy to insert into existing patch panels, wall sockets or portable network setups. As a passive adapter, it preserves the original signal path for straightforward data or voice pass-through and enables quick, temporary sharing of a single RJ45 outlet between two devices.

Suitable for

• Sharing one RJ45 outlet between two telephones or VoIP adapters over short distances
• Simple, temporary network expansions where a switched port or additional cabling is unavailable
• Home or small-office setups for non-critical Ethernet links and basic data tasks

Key specifications

• Connector type: RJ45 to dual RJ45 passive splitter
• Function: Passive division of a single Ethernet/telephone line into two outputs
• Compatibility: Works with 8P8C RJ45 jacks used in Ethernet and many telephone applications (note: not a network switch)
• Signal type: Suited for short-distance data and voice pass-through; not intended for long-haul or high-performance switched networks
• Power: Passive device — no external power required
• Form factor: Compact, inline adapter for quick plug-and-play installation

How to use

Connect the single RJ45 plug of the splitter into the wall socket or network port. Plug the two target devices into the splitter's outputs using standard RJ45 patch cables. Because the device is passive, it does not perform switching or manage network traffic; ensure connected devices and cabling meet the intended use (voice or basic data). For Ethernet situations, verify that the connection method matches the network topology — the splitter does not replace a network switch and is not suitable for creating independent, simultaneous full-speed Ethernet links over one physical port.

Usage recommendations

Use this passive splitter for short-distance or temporary scenarios such as connecting two telephones or simple data devices to one outlet. Avoid relying on it for critical or high-bandwidth Ethernet connections; for stable, simultaneous network links use a network switch or additional cabling. Inspect connectors and cables for wear and ensure proper seating to maintain reliable signal pass-through.
