Page 3: Product Overview
Product Overview Fiber-Span provides product to enable RF signal to be distributed via optical fiber cable. RF signal sources can be used from over the air (OTA) from a Radio Base Station (BS), OTA from handheld devices, or directly from a BS radio. RF signals are converted to modulated light for transport through optical fiber media to remote locations. -

Alarms The Opt in Alarm interface uses a wire contact header (supplied) that will plug into the Opt in Alarm sockets. Connection of alarm wires to the wire contact header requires a small standard flathead screwdriver. The connections are dry contact relay terminals. - Page 8 range. Make all RF connections and terminate all unused RF connections before applying AC Power. Figure 8. RRU/IHU (Wall Mount Version) Bottom Side Figure 9. RRU/IHU (Rack Mount Version) Alarms The alarm interface uses a circular connector. The connections are dry contact relay terminals.
- Page 9 See LED alarm indicator locations in Figure 10. A receiver alarm is triggered by excessive optical loss. The transmitter alarm is triggered when the laser transmitter runs over bias. The PA alarm indicates that the PA is overdriven. The Door / Fan alarm indicates when the door is left open or if a cooling fan fails.
