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.

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 WiFi 2.4 GHz

Slot 2 Unused, but accommodates WiMAX

Slot 3 iDEN 800/900 MHz

Slot 4 AWS 2.1 GHz

Slot 5 700 MHz

Slot 6 Cell 850 MHz

Slot 7 PCS 1.9 GHz

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.
