Theory of Operation
1 Introduction
This manual contains information and procedures for installation, operation, and maintenance of
the LinkNet Uniserv Unit RF-FIBER Interface Modules. The manual is organized into the following
chapters:
Chapter 1 Theory of Operation Chapter 5 Operation
Chapter 2 Mounting Chapter 6 Antenna Installation
Chapter 3 Connections Chapter 7 Laser Safety
Chapter 4 Remote Module Chapter 8 Return for Service
1.1 Theory of Operation
The USU RF to Fiber Modules provides a single-band link from a Headend distribution center to
multiple local antennae. RF signals are distributed over a pair of single mode fiber optic distribution
lines to each USU Remote.
Each Headend module can interface to multiple remote modules, the number depending upon the
Headend model.
The Headend modules do not
Note! The remote module fiber optic I/O's are band specific, but the Headend fiber optic I/O's are not;
the Headend I/O's may be used for any band.

Figure 2 Typical Block Diagram
In the LNKFIB-H03 Headend module, the eight fiber optic pairs are in two banks (A & B) of four, with
the RF connections combined inside the module in those groupings. The LNKFIB-H04 is identical, but
with one bank of four removed.
Each of the groups of four consists of a single RF Input feeding a single Laser Transmitter split optically
to four fiber optic outputs. The four matching fiber optic Inputs each go to their own photodiode receiver,
followed by a 0 to -15dB digitally controlled attenuator providing uplink gain control. The RF signals
from the four digital attenuators are combined into a single RF output.
The group of four RF input and output combining inside the module alleviates the need for external
combining / splitting.
