GPS – RFoF
The GPS Over Fiber Link by Optical Zonu provides a simple, cost-effective and reliable RF connection between the GPS antenna and receivers where coaxial cable is impractical. Each link is wideband and supports any of the global GPS frequencies – current or future. The high dynamic range of the system ensures a transparent pass-through with no distortion. A low noise pre-amplifier ensures a margin on signal-to-noise ratio while keeping the signal in the most linear operating Range of the Fiber optic link. The unit housing is a compact IP-50 enclosure. The link supports one GPS antenna. A Built-in Bias-T provides the needed DC power for the active GPS antenna. While the Optical Zonu GPS Fiber Transport Link can be used for point-to-point applications, the link may also be optically split into 8 ways to provide cost-effective GPS distribution to multiple locations over lightweight Fiber cable. In addition, the receiver is available with either one or two RF outputs.
These linear RFoF Transceivers provide an excellent alternative to coaxial cable for distances from 100m to over 10 km. The standard optical connector is the SC/ APC (FC/APC is also available) for low back reflection. This, along with the integrated optical isolator, helps guarantee transparent transport without additive Noise or spurious signals.
The laser diode is an uncooled device that provides stable operation over the entire ambient Operating Temperature Range of –20 °C to +65 °C. Average Automatic Power Control (AAPC) is utilised for optimal optical power stability over the full temperature range.
The RF interface is a 50? SMA connector, and the Alarm and Monitoring Functions are available through a DB9 connector. The standard unit requires +12 VDC power between pins 4 and 5 of the DB9 connector.
The BiasT option +5V or +12V is for powering the Amplifier inside the GPS Antenna. Optical Transmitter monitors ensure the GPS is functioning correctly and if NOT, it optically reports the condition to the GPS optical receiver by blinking the light ON/OFF. The OZ600 Receiver has a built-in active DC Antenna load which goes high impedance if there is a Fibre fault or remote Antenna failure condition.

FAQ: Are GPS Repeaters permitted in Australia?
GPS repeaters can be legal in Australia, but some restrictions and regulations must be followed to ensure compliance with the law.
The Australian Communications and Media Authority (ACMA) regulates the use of GPS repeaters in Australia, and it is important to comply with their regulations to avoid fines or legal action. In general, GPS repeaters are only legal if they meet specific requirements, such as:
- They must be designed to receive and re-transmit GPS signals without causing harmful interference to other wireless services.
- They must be licensed by the ACMA and operated in compliance with the conditions of the license.
- They must not be used to interfere with or disrupt GPS signals used by emergency services, aircraft, or other critical applications.
It is also important to note that GPS repeaters that are not properly licensed or operated in compliance with the ACMA regulations can cause harmful interference to other wireless services and disrupt GPS signals, which can have serious consequences. Therefore, it is recommended to consult with the ACMA or a qualified professional before installing a GPS repeater in Australia.
Cellular Repeater CDMA, Next G
Information from ACMA
Mobile phone boosters/amplifiers, regardless of where they are intended to be used by third parties (i.e. not a mobile telecommunications carrier), are a prohibited device and cannot be legally used in Australia.
All radiocommunications transmitters operating in Australia, its territories and its territorial waters do so under the authority of an Australian Communications and Media Authority (ACMA) issued spectrum, apparatus or class license.
A mobile telephone booster/amplifier and/or repeater is a radiocommunications transmitter and therefore can only be operated in Australia under the authority of an ACMA issued radiocommunications license, or with the permission of the current licensees.
- The radio spectrum in which these mobile telephone booster/amplifiers and/or repeaters operate, is exclusively licensed to the mobile telephone carriers (including Telstra, Optus and Vodafone).
- There are no mobile telephone booster/amplifiers and/or repeaters licensed for use in Australia, with the exception of those operated by the mobile telephone carriers who may install and operate these or similar devices as part of their networks under their licenses.
- Third parties cannot be given licenses by the ACMA to operate mobile telephone booster/amplifiers and/or repeaters in this spectrum. You would need the permission of the licensees (the mobile telephone carriers.
There have been several instances where mobile telephone booster/amplifiers and/or repeaters have been imported into Australia from overseas and the subsequent use has resulted in interference to mobile telephone networks. ACMA has seized several of these devices and appropriate compliance enforcement action was taken under the Radiocommunications Act 1992.
Severe criminal penalties, including court imposed penalties up to $165,000.00 or 2 years imprisonment, exist under the Radiocommunications Act 1992 for the unlawful possession of and/or the use of these devices. Telecommunications carriers may also initiate civil legal action against users for any losses suffered due to the use of these devices the users may subsequently be able to take civil action against the suppliers.
Summary of mobile phone booster prohibition
You cannot legally use a booster or repeater for better mobile phone reception.
Reasons:
- A booster or repeater is classed as a transmitter.
- You need a licence to operate a transmitter.
- The booster would be re-transmitting in the same radio frequency spectrum covered by the Spectrum licences owned by the mobile service providers (the Carriers).
- You cannot legally transmit in the frequencies allocated to the carriers by their licences, without their permission.
Mobile phone boosters banned – Information for consumers:
http://www.acma.gov.au/theACMA/mobile-phone-boosters-banned-information-for-consumers
Alternatives:
Contact your mobile carrier (you mobile phone service provider) to ascertain if they are able to offer you any alternatives, or:
You might find the following alternatives suggested if you were to search on-line for solutions and information, depending on which is most suitable for your phone and situation:
- install a “car kit” for your home, or
- install an external antenna which is cable connected inside either directly to connector on the phone or via an inductive coupler if your phone is without provision for connection of an external antenna, or
- install a passive indoor antenna. Pick up some coaxial cable (enough to go from the outside of your home to the inside) and two antennas with coaxial connections from your nearest electronics store. Place your outside antenna in a location with a strong signal and run the cable into your home. Try running your cable through a window at first to make sure the passive antenna will help improve signal strength before you drill into your home. After connecting both the outdoor and indoor antennas check your signal strength, as it should be improved at this time.
You may still need to check with your Carrier or Service Provider (i.e. Telstra, Optus, 3, Vodafone, Virgin etc) to verify that these suggestions are acceptable under their Spectrum Licence conditions.
