GPS Over Fiber (GPSoF)
Our GPS over Fiber solution is L-Band (UWB) Optical Transmitter designed to distribute the GPS\GNSS timing signals to various electronic devices such as Cell Site Routers, Data Centers and OLT\rOLT that require precise timing.
The GPS signals are converted into optical signals distributed to various parts of the building, parking garage, airport hanger, datacenter, CSR (Cell Site Routers), Remote PON OLT (rOLT) which are converted back to GPS signals and connected to various timing devices. This allows one GPS antenna to provide timing signals to essential parts of the network that require precise time, which cannot be reached by gps amtenna using coax cables.

Distribution of the GPS signal over long distances
Converts the RF signal to an optical signal, then
back again for datacenters, cell site routers, parking garages, airplane hangers.
GPS Over Fiber
GPS
over Fiber system for applications where coax
cannot be used to route the GPS signal to base
stations. With more centralized RAN and large-scale
DAS applications, there are many cases where
the GPS antennas are located too far from the
base stations for coaxial losses to be acceptable.
To overcome this issue, the GPS over Fiber
system converts the RF signal to light, transmits
it over the fiber, and then restores the light to
the original RF signal. Working in contrast to the
many systems that employ a bulky remote unit –
which requires power and separate mounting
space – as well as a large master unit encompassing
an active GPS splitter, OlsonTech has rethought
the process and designed a fiber-optic replacement
for the coaxial cable. Instead of a master unit
and a remote unit, the system uses an electrooptical converter (E/O converter) at the antenna
and an opto-electrical converter (O/E converter)
near the base station.
By employing this method, the E/O converter
becomes a small, compact unit that connects
directly to the GPS antenna. The O/E converter handles all alarms and is a
compact unit. It can be used to power the E/O
converter and can be connected to standard
GPS splitters with full support for their redundancy
functionality. This means that the GPS over Fiber
system fully emulates the behavior of a passive
copper cable and GPS antenna, allowing any
device that is normally connected to the GPS
antenna to maintain proper operation when
connected to an O/E converter.
Interconnecting the two units i.e. E/O converter
to the O/E converter is a thin hybrid cable
comprised of fiber and power, which means no
power source is required at the GPS antenna.
The individual link support for each GPS antenna
allows for the flexibility of using a normal coaxial
configuration and simply replacing each coax cable
from a GPS antenna with an E/O converter, an O/E
converter, and a hybrid cable. With a healthy link budget the Optical receiver can be mounted miles away.
E-O
The E/O converter directly connects to any active
GPS antenna and converts the GPS RF signal to
an optical one. Powered through a hybrid cable,
the E/O converter not only transfers the GPS signal
to the O/E converter, it also supplies power to
the GPS antenna and detects any antenna faults,
relaying the alarm information to the O/E converter.
O-E
The O/E converter receives the optical signal
from the E/O converter via the hybrid cable
connection and converts it back to an RF signal.
The O/E converter also sends power to the E/O
converter via the same fiber cable
