TELEGÄRTNER T-Adapter Cat5e σε 100Base-T/ISDN RJ45 splitter (J00029A0013)

Network T-Adapter that splits one Cat5e cable into two RJ45 ports, enabling simultaneous 100Base-T Ethernet and ISDN S0 bus transmission over a single 4-pair cable. This compact splitter eliminates the need for additional cabling in structured office environments.

Advantages

Utilises all four pairs of a Cat5e cable to carry two independent services, doubling the functionality of existing infrastructure. The ABS plastic housing is lightweight yet durable, and the unshielded design is ideal for typical office installations. With a wide operating temperature range from -10°C to +60°C, it performs reliably in diverse conditions.

Suitable for

• Structured cabling systems in office buildings
• Integrating legacy ISDN telephony with modern Ethernet networks
• Reducing cable clutter where only one Cat5e run is available
• Small to medium business network expansions

Key specifications

• Input: 1x RJ45 female
• Outputs: 2x RJ45 female
• Supports 100Base-T Ethernet and ISDN S0 bus
• Category 5e performance
• Colour: Light grey
• Housing: ABS plastic
• Unshielded (UTP)
• Operating temperature: -10°C to +60°C
