Data splitter DATACOM 4253 STP 1xPC to 1TEL and 1TEL

The DATACOM 4253 STP is a shielded data splitter that lets one cable carry a PC data connection and two telephone signals (1xPC to 1TEL and 1TEL). It provides STP shielding to reduce electromagnetic interference and is intended for simple wiring setups in small offices or home installations where a single network/phone line must be divided into two telephone outputs.

Advantages

The STP shielded design lowers susceptibility to EMI, preserving signal integrity for both the PC and telephone lines. The compact RJ45 plug-and-socket arrangement enables easy inline installation without additional tools or active components. Pin mapping follows standard RJ45 assignments to separate the PC pair from the two TEL outputs.

Suitable for

• Small office wiring where one cable needs to serve a PC and two telephones
• Home installations that require splitting a single network/phone run into two TEL lines
• Temporary setups or low-complexity cabling without a need for active splitting devices

How to use

Insert the male RJ45 plug of the splitter into the network outlet or patch cable carrying the PC and telephone signals. Plug the telephone devices into the two female RJ45 sockets. Ensure connectors are fully seated. No power or configuration is required; the splitter passively redirects the appropriate wire pairs to the TEL outputs according to the printed pin mapping.

Usage recommendations

For reliable performance, use short cable runs and quality shielded cabling; avoid running the cable alongside high-voltage power lines. This passive splitter is intended for basic voice and low-speed data separation—verify compatibility with your devices before permanent installation.
