Remote Fiber Node (RFN) User Manual 2. 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.

Remote Fiber Node (RFN) User Manual 5. Warnings Invisible radiation exits from areas labeled “Aperture” All fibers at both ends of the optical link connected before applying power to either fiber transceiver unit and remote fiber node will prevent exposure. Follow and comply with all site safety policies. Exclamation point denotes attention to statement. Terminate all RF ports with a 50 Ohm load. While in operation do not touch RFN front façade heat sink because surface is very HOT.
Remote Fiber Node (RFN) User Manual 6. 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.
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.
Remote Fiber Node (RFN) User Manual Although it accommodates both paths, circuitry is kept shielded providing 120 dB of isolation between them which prevents any RF crosstalk. The iDEN uplink has 2 independent internal inputs that combined iDEN 8 and iDEN 9 allocated bands. Downlink last stage output power amplifier accommodates both iDEN 8 and iDEN 9 frequency bands.
Remote Fiber Node (RFN) User Manual Instrument operates in the UL 1710-1755, DL 2110-2155 MHz region. Figure 5 displays Plug-in Cell, PCS, and AWS RF connections in rear which are the same for all three bands. Figure 5 6.4. 700 The 700 Plug-in is a bi-directional service module comprising of uplink and downlink circuitry. Internally it houses all the devices that conditions, filters and amplifies the specified frequency band while rejecting the adjacent family bands operating within the chassis.
Remote Fiber Node (RFN) User Manual 6.5. Cellular The CELLULAR Plug-in is a bi-directional service module comprising of uplink and downlink circuitry. Internally it houses all the devices that conditions, filters and amplifies the specified frequency band while rejecting the adjacent family bands operating within the chassis. Although it accommodates both paths, circuitry is kept shielded providing 120 dB of isolation between them which prevents any RF crossover.

Remote Fiber Node (RFN) User Manual 7.2. Plug-in Figure 8 7.3. 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.

Remote Fiber Node (RFN) User Manual DWDM Configuration Tucked in the RFN lower left tier is the Add Drop Multiplex arrangement, housing all the optics and external interface connections. Designated optical channels are ITUs 26,30,34,38 for the downlink (DL) path and ITUs 26, 30, 34 for the uplink (UL) path which are dedicated for the Service Groups (SG1, SG2, SG3) excluding the Ethernet paths. Duplex configuration allows use of the same ITU channels, see Error! Reference source not found..
Remote Fiber Node (RFN) User Manual Beneath the optical housing is a shallow splice tray compartment for the end-user to loop, make interconnections, and secure the fibers.
Remote Fiber Node (RFN) User Manual 8. 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.
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.
