Altronix HUBWAY8DI 8-Channel UTP Transceiver Hub

Altronix HUBWAY8DI 8-Channel UTP Passive Transceiver Hub

Overview

The Altronix HUBWAY8DI is a 1U passive transceiver hub engineered for distributed video transport over standard unshielded twisted pair (UTP) cabling. This device consolidates eight independent transceiver channels into a single rack-mount unit, eliminating the need for individual transceiver pairs and streamlining installation in centralized security infrastructure. The HUBWAY8DI integrates a 24/28VAC isolated power supply that accommodates both 115VAC and 220VAC input, providing single-source power delivery for remote video head-end equipment without external power conditioning.

Designed for security integrators and system installers, the HUBWAY8DI supports analog video transmission up to 750 feet over UTP—a critical distance specification for large-scale deployments where fiber infrastructure is not cost-justified. The passive transceiver architecture eliminates active amplification noise and maintains signal integrity across extended runs, making it suitable for both new installations and retrofit projects where existing twisted-pair infrastructure can be leveraged.

Key Features

• 8-Channel Passive Transceiver Configuration: Eight independent transceiver pairs housed in a single 1U form factor, reducing equipment footprint and interconnect complexity.
• Video Range to 750 Feet: Supports analog video transport over UTP cable up to 750 feet, compliant with standard twisted-pair loss characteristics.
• Integrated 24/28VAC Isolated Power Supply: Built-in transformer-isolated power supply eliminates ground-loop noise and provides clean DC power for remote devices, removing the need for external power injection modules.
• Dual AC Input (115VAC/220VAC): Single unit supports both North American and international utility voltages with automatic detection and switching.
• UL Listed & CE Marked: Meets North American and European safety certifications for commercial security installations.
• Passive Transceiver Design: No active amplification means lower power consumption, reduced EMI, and simplified maintenance compared to active hub architectures.
• Rack-Mount 1U Format: Standard 19-inch rack compatibility for integration into centralized video distribution and power infrastructure.
• Isolation & Noise Immunity: Integrated isolation topology prevents ground loop noise that degrades video signal clarity in large installations.

Integration & Compatibility

The HUBWAY8DI functions as a hub-and-spoke distribution point for analog video head-end systems. Each transceiver channel accepts a pair of twisted-pair lines from field-mounted cameras or video encoders and delivers balanced, impedance-matched signals suitable for direct connection to DVR, multiplexer, or matrix switch inputs. The integrated power supply output is available to remote devices via dedicated power leads, supporting typical surveillance camera and encoder power budgets. This architecture enables centralized power management and video signal conditioning in a single 1U device, reducing rack space and cable routing complexity in master control rooms and equipment closets.

I have specified the Altronix HUBWAY8DI on several large-campus security deployments where fiber infrastructure was cost-prohibitive and existing UTP runs were available. The passive transceiver design is a key advantage—it eliminates the noise floor associated with active repeaters and delivers clean video across the full 750-foot distance specification when properly balanced and terminated.

Technical Highlights:

• Isolated Power Supply: The integrated 24/28VAC supply with transformer isolation is critical in large multi-building installations. It breaks ground loops that would otherwise introduce 60/50 Hz hum into the video signal.
• Dual Input Voltage: The ability to operate from both 115VAC and 220VAC input in a single unit simplifies inventory and deployment logistics, particularly for international projects or facilities with mixed power infrastructure.

Deployment Considerations:

• The 750-foot UTP distance is achievable only with quality twisted-pair cabling (Category 5e minimum) and proper impedance termination at the hub and remote end. Verify cable run length and quality before installation.
• Place the HUBWAY8DI in a climate-controlled equipment room with adequate ventilation. The passive design generates minimal heat, but the power supply benefits from stable ambient temperature.

For integrators managing multi-site surveillance networks with legacy UTP infrastructure, the HUBWAY8DI eliminates the need to purchase and manage eight separate transceiver pairs. The consolidation, isolation, and integrated power supply make this a cost-effective hub architecture that has proven reliable in field deployments.
