Network UTP Splitter DATACOM 4203 with 3x RJ45 8P8C ports

DATACOM Rozdvojka UTP CAT5E 3xRJ45 (8p8c-1M/2F) is a compact passive UTP splitter that provides three RJ45 8P8C ports to duplicate a single CAT5E network line. The device offers a simple physical parallel splitting solution for environments where one network or telephone signal must be made available at multiple points without rewiring. It is a passive connector assembly and does not function as an Ethernet switch.

Advantages

The DATACOM 4203 splitter requires no power and is plug-and-play, allowing quick parallel connection of one input to two additional RJ45 outputs. Its compact design is easy to install and carry, and it preserves the original pinout (1–8) across all ports to maintain straightforward compatibility with existing UTP cables and devices.

Suitable for

• Temporary expansion of a CAT5E/UTP line to two additional RJ45 endpoints
• Splitting a single telephone line to ring at two locations
• Simple field tests or short-term network cabling adjustments where only one active connection is needed at a time
• Small office or home setups where rewiring is not practical

Key specifications

How to use

Connect the source UTP cable to the input RJ45 port of the splitter and plug the desired devices or cables into the two output RJ45 ports. The device mirrors the single input signal to both outputs in parallel. Note that only one connection can be active for two-way communications at any moment; simultaneous independent use of both outputs for networking is not supported.

Usage recommendations

Use the splitter only for simple duplication of a single line (for example, to make a phone line ring in two places or to provide a selectable network connection). Do not use it as a replacement for an Ethernet switch or as a method to combine multiple independent network links. For permanent multi-user network installations, use proper switching or routing equipment.
