Part Number F-GPS-TX-WE / F-GPS-TX-RM
The Thor Fiber GPS over Fiber outdoor weather kit allows you to send a GPS signal over long distance for synchronizing cellular base stations.
Allows transmission of the two main signals in the GPS band, L1 and L2, at 1575.42 MHz and 1227.6 MHz.
By using built-in LNA , this GPS over Fiber Link is designed to offer a very low noise figure
Sending GPS over the coax is very dificult to do over long distances so our GPS system has many diferent advantages:
Units have LCD dispalys to display RF and Optical levels that is built into our units
The transmitter shows incoming RF level and optical output power. The receiver has built in Optical power meter and RF ouput level meter, allows simple troubleshooting.
Thransmitter is waterproof and Receiver is rackmountable in 1RU chassis.
The Transmitter has Bios-T and can power Active GPS antena.
Both transmitter and receiver have dual redundant power supplies, making them very robust and pragmatic for commerical architectures.
These systems are very easy to deploy and can offer various configurations very many applications.
Main receiver is 19' rack mountable but tranmitter has a built in compact enclosure which is deployable in any environment.
Units are used as a point to point transmission from the tramsitter to the receiver, but the transmitter can be accompanied with our optical splitters which can be used for point to multipoint applications (star configuration) 1x2, 1x4, 1x8 ,1x16 and 1x32
It's also possible to add additional splitters on the receiver side and have up to 6 GPS ouputs on the receiver (special order).
You can add 1x2 optical splitters to the receiver and use them as in line from one receiver to the next in a cascading configuration for easy distribution.
GPS-over-Fiber Applications:
IMPORTANT NOTE*** (it is very important to interface our unit with SC/APC - Angle Polished Connector to avoid any light reflections.
If your fiber is terminated with the SC, ST, FC /PC flat connector, you need to use an optical jumper from PC type to SC/APC for proper conversion.
Transmitter -Weatherproof Enclosures NEMA 4 and dual power supply, LCD display, RF and Optical meters built in

Note 1: C/IM3 is defined as the ratio between the peak of carrier signal and triple beat (IM3) by using a two-tone test (1.0GHz and 1.1GHz).
Note 2: The input level range is 47~67dBµV when AGC attenuation=0; the input level range is 48~68dBµV when AGC attenuation=1. That is to say, AGC attenuation increase 1dB, the input level will corresponding increase 1dB and the optical receiver output level will also increase 1dB (the same optical power received). The reduce rule is just the same.
