Overview

Base Stat ion( s)
Theory Of Operation
The USU RF to Fiber Modules provide a single-band link from a Head-End
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 Head-End Module can interface to multiple Remote Modules, the number depending
upon the Head-End Model.
The Head-End Modules do not
transmit directly out into the air.
Note that the Remote Module Fiber-Optic I/O's are band specific, but the Head-End
Fiber-Optic I/O's are not; the Head-End I/O's may be used for any band.
Typical Application
A typical installation would be....
SMF = Single-Mode Optical Fiber
Any r equired
Amplifiers, Filters,
Couplers, Etc.
USU RF to Fiber
Remote Modules
These may be single or
mult iple units, and are
usually grouped on floors
of a building, mounted in
Elect rical Ro oms.

LNKFIB-H03
Head-End Module
Single-Mode Fiber-Optic Distribution Lines and provides a single
duplex Antenna RF Distribution connection. This model covers
800MHz Trunking / iDEN / Public-Safety Services
(806-824 MHz / 851-869 MHz).
As above, but this model covers 800MHz Cellular Services
(824-849 MHz / 869-894 MHz)
As above, but this model covers 900MHz Paging Services
(896-902 MHz / 928-941 MHz)
As above, but this model covers 1.9GHz PCS Services
(1850-1910 MHz / 1930-1990 MHz).
Power Supply for 1 US Remote Module.
This is a 1U high, 19" Rack-Mount Module providing low signal
level interfacing between Head-End RF Modules and 8 Pairs of
Single-Mode Fiber-Optic Distribution Lines. The 8 Fiber-Optic Pairs
are in two groups of four, with the RF connections combined inside
the Module in those groupings.

LNKFIB-H04
Head-End Module
This is a 1U high, 19" Rack-Mount Module providing low signal
level interfacing between Head-End RF Modules and 4 Pairs of
Single-Mode Fiber-Optic Distribution Lines. The RF connections for
the 4 Fiber-Optic Pairs are combined inside the Module.

In the LNKFIB-H03 Head-End Module the
of four, with the RF connections combined inside the Module in those groupings. The
LNKFIB-H04 is identical, but with one Bank of 4 removed.
8 Fiber-Optic Pairs are in two Banks (A & B)
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.
