PRELIMINARY Fiber Optical Cables
A.2 Fiber Optical Cables
• Connects Main Hub to Expansion Hub(s)
• Transmits (downlink) and receives (uplink) cellular and PCS signals
• Use industry-standard 62.5µm/125µm MMF or Corning SMF-28 fiber, or equiva-
lent (SC/APC [angle-polished] connectors only)
• Distances:
• Multimode Fiber: up to 1.5 km (4,921 ft) – 3 dB optical loss maximum
• Single-Mode Fiber: up to
6 km (19,685 ft) – 3 dB optical loss maximum
A.3 Coaxial Cable
• Connects a Main Hub to a repeater or base station (N-type connectors)
• Connects an RAU to a passive antenna (SMA connectors)
