INTRODUCTION

1. Introduction

The QFMN device is a cost effective mini indoor ber node.

QFMN provides the user with a two-way 870 MHz node with excellent RF and optical performance. The forward optical

detector will accept either 1310nm or 1550nm wavelengths. The QFMN device is designed to operate with a nominal optical

input level of 0 dBm that provides the best RF performance.

QFMN also provides a factory installed 5 to 42 MHz Fabry-Perot return path transmitter with a built-in gain potentiometerto

set the optimum drive level to the laser driver amp and a factory selected plug-in-pad after the laser driver amp to set the
optimum laser RF drive level.

The QFMN device can provide RF output levels of +45 dBmV. For set-up and monitoring purposes, QFMN provides a -20 dB
Forward RF test point located at the output of the amplier and a -20 dB test point for the return path located after the laser

driver amp. Internally a 10-segment LCD optical power meter is available to aid in proper set-up of the forward path optical
input.
