Corning WB-B4U Wide Band Base Unit: The Foundation of Your MobileAccess DAS

The Corning WB-B4U Wide Band Base Unit is the central hub of your Corning MobileAccess Distributed Antenna System (DAS), providing the essential RF to optical conversion for seamless mobile connectivity. This robust 4-port unit supports up to four remote units (RHUs) over single-mode fiber, ensuring reliable signal distribution throughout your facility. With the option to support up to eight remote units, the WB-B4U offers scalability for future network expansion.

• Universal Mobile Service Support: Handles RF to optical conversion for all mobile services compatible with Corning MobileAccess DAS, ensuring comprehensive coverage for your users.
• Scalable Architecture: Supports up to four (and optionally eight) remote units, providing flexibility for current needs and future growth. Expand your coverage area efficiently and cost-effectively.
• Centralized Management: Integrates seamlessly with Corning MobileAccess’ centralized management system, offering proactive, end-to-end monitoring and control of your DAS network. Simplify network administration and optimize performance.
• Alarm Support: Equipped with dry contact alarms, enabling integration with existing building management systems for enhanced monitoring and rapid response to potential issues.
• Intuitive Indicators: Features local indicators for optical link status, allowing for quick visual verification of network connectivity and simplified troubleshooting.
• Fiber Flexibility: Available in both multimode and single-mode fiber versions, accommodating diverse installation requirements and cable infrastructure. Single-mode fiber supports longer distances for larger deployments.

Technical Specifications:

• RF Input Power: Up to 10 dBm
• Optical Output Power: < 3.0 mW
• Optical Fiber: Single-mode (9/125 µm) or Multimode (50/125 µm or 62.5/125 µm)
• Maximum Distance: 2 km (single-mode), 300m (multimode) – See Multimode Fiber Qualifications below
• Operating Temperature: 0° to +50°C (32° to 122°F)

Multimode Fiber Qualifications:

When using multimode fiber, specific criteria must be met to ensure proper operation up to 300 meters:

• Both the base unit and remote hub must be multimode compatible.
• All fiber within a given length must be the same core diameter (50/125 or 62/125 µm).
• All bulkhead adapters must be single-mode SC/APC (green) adapters.
• Terminations must be direct fusion splices or Corning MobileAccess specified patch cords.

Ideal Applications:

• Large venues such as stadiums, airports, and convention centers
• Enterprise buildings and campuses
• Hospitals and healthcare facilities
• Educational institutions
