Introduction The FS47 Remote Fiber Node (RFN) is a multi-service equipment designed to extend multiple wireless carrier services such as 700, 800/900 iDEN, Cellular, PCS, AWS, WiFi and WiMAX. The RFN’s unique design allows it to be easily adapted to meet the demands of new generations of communication schemes. All three DAS interface ports are capable of providing a high linear output power greater than 25 dBm per band. Incorporating a unique feature, the system provides three downlink/ uplink RF ports for connection to distributed antenna systems (DAS) capturing distributing and launching, the many frequency bands at once using Dense Wavelength Division Multiplex (DWDM) technology allowing simultaneous extended wireless coverage from many of the carrier services. The RFN utilizes a rugged enclosure to withstand high vibration, and the front façade of each plug-in module has a large heat sink for efficient heat dissipation. The RFN employs modular construction, offering trouble-free access to individual carrier services for maintenance and upgrade, without disrupting the operation of any of the others. ©Copyright 2011, Fiber-Span Page 3 of 38 Remote Fiber Node (RFN) User Manual 3.

Product Overview A Remote Fiber Node (RFN) chassis has 7 compartments that houses a variety of modular plug-in modules, of which their internal components and rear-mount mechanisms are mapped according to operating frequency bands. Chassis inside slots have a mating rear receptacle that provides primary power to the plug-ins as well as the RF Input / Output interface functions. There is no optical interface between any of the plug-ins and the back receptacle. As viewed with heat sink facing you, (from left-to-right) each chassis slot is dedicated to a frequency band; a list of which is shown in Figure 1 below: Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 Slot 6 Slot 7 WiFi 2.4 GHz Unused, but accommodates WiMAX iDEN 800/900 MHz AWS 2.1 GHz 700 MHz Cell 850 MHz PCS 1.9 GHz Figure 1 Figure 2: Frequency Band Layout Internally, the Plug-ins employ similar circuitry and layout designs using filters, attenuators, low noise amps and power amplifiers for their respective allocated frequency band, excluding the WiFi Plug-in. For future upgrade purposes, the factory may re-position frequency band plug-ins slots from that shown here. All the plug-ins are HOT-swappable which allows removal and replacement while the RFN is ON and operating. ©Copyright 2011, Fiber-Span Page 8 of 38 Remote Fiber Node (RFN) User Manual 6.1. WiFi WiFi is short for “Wireless Fidelity”, and uses IEEE 802.11 specifications with protocols for communicating end-to-end via a wireless network. The WiFi Plug-in has 3 access points each one independently going to antenna 1,2 and 3 with the Channel set to: Access‐Point Position Antenna ID Channel Name Left ANT 1 WiFi Channel 1 Center ANT 2 WiFi Channel 6 Right ANT 3 WiFi Channel 11 For 802.11g operation, typical receive sensitivity ranges from -73 dBm at 54 Mbps to -96 dBm at 1 Mbps. For all practical purposes, as Mbps data rate doubles sensitivity drops by 3 dB. Indoor wireless coverage ranges from 460 ft. at 1 Mbps to 105 ft. at 54 Mbps data rate. Outdoor use (compared to indoor) with no obstruction distance doubles between 1- 48 Mbps, but not much higher of 120 ft. at 54 Mbps. Measurements were taken with a 2.2-dBi dipole antenna for 2.4 GHz. Maximum power draw per access point is 12.95 Watts x 3 equals 38.85 Watts Total. For added isolation access point ports have an in-line band pass filter. Instrument operates in the 2400-2483.5 MHz region. Figure 3 displays Plug-in WiFi RF connections in rear.

System Block Diagram Figure 9 demonstrates a 1 x 4 system link configuration comprising of 4 RFNs and Headend segments that makeup a link, such as OMU, FTU-RF, FTU-E and RIS. RIS is the last F-S equipment interfacing with the end-user Base Transceiver Station (BTS). In this section, an overview is provided of the Headend equipment incorporated as part of a typical RFN application. Optical Multiplex Unit (OMU) houses all the passive optical devices interfacing with incoming and outgoing fiber bundles which are then neatly individualized, routed and channeled to interface with the Optical Add/Drop Multiplex (OADM). Next, each designated ITU connection interfaces with the FTU-RF and FTU-E. Fiber Transceiver Unit – Radio Frequency (FTU-RF) houses all the active optical devices that converts light into electrical and vice-versa launches light from received electrical. In the receiver there is filtering, post amplification, and gain adjustability for fine tuning as required. ©Copyright 2011, Fiber-Span Page 14 of 38 Remote Fiber Node (RFN) User Manual Fiber Transceiver Unit – Ethernet (FTU-E) houses the media converter. ??-Write a brief summary.Radio Interface System (RIS) houses all the RF devices that condition, filter, rssi and control gain that is required between the BTS and FTU-RF, in part because an ideal RF level into FTU is 0 dBm and levels from BTS are considerably higher up to 30 dBm. As planned, based on the service group, configuration for simplex, duplex and full duplex or combination of them are arranged in the RIS. Fibers interconnecting the FTU-RF, OMU and RFN are 9/125 um single mode. Fiber medium operational range is from 0 to 8 dBo optical loss. Figure 9 7.4.

General 8.1. RF Notwithstanding the specific operating frequency band of each plug-in, circuitry are alike with a 40 dB gain on the uplink path and 70 dB gain on the downlink path. Uplink noise figure is optimized to be lower than 2. Downlink can drive DAS in excess of 25 dBm per band. And In both paths, for tuning, the same attenuator device is implemented that provides 31 dB of range. Multiplexer is the external gateway that combines all the plug-in up/down paths user interface ports which introduces 12 dB loss for Ant1 and Ant 3 while Ant 2 has an additional 6 dB more loss. 8.2. Optical All optics are housed in the lower left tier compartment called “Optical Stack”, namely because carefully inside, sections are one on top of the other. Beginning with the FOTXs, middle FORXs and last the OADMs. FOTX further discussion Each unique 1.5 um wavelength is routed into their corresponding OADM channel exiting the common conduit and launched through the interface optical port uplink path. At factory, FOTXs are normalized called TX Set-point that regulate batch with a consistent resultant output. Laser incorporates average optical power feedback keeping output power steady over temperature and lifetime. For best performance laser bias is also tuned. A typical UL FOTX optical output power is 6 dBm, minus 2 dB loss through the OADM for a net launched of 4 dBm. Result using Optical Meter will be the composite power. But with an optical spectrum analyzer (OSA) one or all side-to-side wavelengths spectrum are displayed on screen for precise measurement. Figure 13 demonstrates how the optical configuration for the downlink behaves as a function of muxing the lasers through the OADM. Measurement at the optical port with an optical meter yields 8.8 dBm, on the other hand measuring with an OSA outcome is 4.0 dBm for each laser. For the uplink path each laser launch power is typically 6 dBm but no higher than 8 dBm and would put composite launched power at 10.8 dBm. ©Copyright 2011, Fiber-Span Page 19 of 38 Remote Fiber Node (RFN) User Manual Figure 13 Note: Allow for 0.25 dBo loss for every interconnection. FORX discussion On the opposite side, complimenting is the fiber optic receiver (FORX) which converts the optical input to an electrical output for the downlink (DL) path. By also adding an OADM in the receiver side only matching light goes through while rejecting all others. Most photo detector optical input limits are about 8 dBm, but the system receivers will never see such high levels, with practical values at 5 dBm or much lower due to the external fiber medium optical loss which is around 4 dBo. Further explanation, with a 7 dBm source optical power at the Headend which is split 4-Ways (-7dBo) then the OADM thru loss (-2 dBo) and a typical (-4 dBo) loss thru fiber medium, putting the upper optical input limit of the fiber receiver at -6 dBm. So the upper limits are unreachable into FORX. Alarm threshold for excessive optical loss is set to -14 dBm which is a 4 dBo margin from the expected fiber medium maximum loss of 8 dBo. ©Copyright 2011, Fiber-Span Page 20 of 38 Remote Fiber Node (RFN) User Manual 8.3.

Switches & Indicators TBD. ©Copyright 2011, Fiber-Span Page 21 of 38 Remote Fiber Node (RFN) User Manual 9. Installation 9.1. Mounting The wall or ceiling bolts securing unit must be sufficiently able to carry the weight of the RFN which must be aligned properly balancing weight throughout the supports. While mounting the RFN a platform underneath must sustained all its weight until all the mounting bolts are tighten and secured. See outline section in this manual for bracket hole dimensions and recommended bolt size. Fully populated unit nearly weighs 200 lbs; therefore proper lifting equipment is required to bear its weight during installation. Do not attempt to install equipment on your own. For proper air flow, keep a minimum clearance of 8 inches in front, underneath and top of the black heat-sink section of the RFN. Allow at least 14 inches in front of the unit for removal and installation of the Plug-ins. Each plug-in comes out independently of the other. Remove all the screws around the perimeter of the plug-in, then to remove the plug-in, hold both handles and pull horizontally straight out from its housing slot. 9.2. Optical Connections Travelling from the outside 4 External 9/125 um single mode fiber strands (2- SC/APC, 2- LC connectors) can either be inserted through the side (left or right) access panels.

Maintenance 12.1. Periodic Inspection Checklist Perform an On-Site assessment of the wireless coverage for use as a baseline, so that upon reinspecting quarterly or semiannually a comparison is made to ensure peak performance throughout equipment lifespan. Test and keep a record of the insertion loss of all the fiber strands that interconnect with the equipment from end-to-end. 12.2. Preventative Measure for Optimal Operation 12.2.1. Optical Maintenance Once optical connectors are secured the ports no maintenance is required. However when necessary to unplug it, immediately cap the tip with cover, see Figure 22. This prevents scratching exposed glass tip which deteriorates performance and possibly becoming unusable. Cover SC/APC Connector Figure 22 12.2.2.
