RFOptic 18 GHz RF over Fiber Bidirectonal Link Setup

This video shows how to connect to each other outdoor radial connectors that are on the tactical fiber and the IP-65 RFoF Box.

Transcript: "Hello, here you see RFOptic's 18 GHz RF over Fiber bidirectional link setup.

It is made of 3 components: the outdoor enclosure, the control room unit, and optical cable reel of 35 meter long. This video is to demonstrate how to connect the outdoor radial connectors.

RFOptic MultiLink RF over Fiber Solutions

RFOptic's multi-link solution comprises of up to 4 links. The 1RU enclosure can hold up to 4 Tx or Rx modules. All modules can be programmed from the same USB connection. Furthermore,  RFOptic also provides multi-link enclosures for 8 units.

Transcript: "Today we will review RFOptic's multilink RF over fiber solutions. RFOptic offers modular RF over fiber solutions. The standalone RFoF modules can be inserted in a variety of enclosures.


The outdoor enclosure for example is IP-65 rated and accommodates up to two Tx or Rx modules. The rack mountable enclosure that you see here, accommodates up to four modules. Each module can be a transmit or receive module. The particular rack mounting unit you see here has 4 Rx modules. This is a typical deployment where the receiver modules are housed indoors at the data center, whereas the transmit modules are housed in a shelter by the antenna. As you can see, all the units are powered up, and the red blinking LEDs indicate that there is no optical signal coming in to them. Once we connect the Tx signal into the Rx unit (as you can see), now the Tx unit over here provides the optical signal and the light on the Rx unit turns green, indicating that the power is good. The rack multiple enclosure enables hot swapping of the modules. If one module is malfunctioning, you don't need to replace the whole system; you can easily take out the defective module and return it to RFOptic provided it's still under warranty. This rather easy to do - we just unscrew the spring screws over here and we can take out the housing. As you can see, the data cable and the power cables are connected to the side. You slide the unit out, and you replace it with the new unit. Then you push it back in and screw the screws back in place. As you can see, while I have replaced the unit over here, I didn’t have to power down the whole system. All the three other modules were still working. There are other advantages using the rack mounting enclosure: It is a slim design, 1U in height.  All four units regardless if they are transmit or receive units are powered by the same AC input. There is a power distribution unit inside, and most importantly, all four units are controlled from the same user interface. There is a USB cable connecting the laptop to the back of the unit and through a distribution hub within the rack mounting enclosure all four units are connected to my user interface. As you can see, there are four units over here and four tabs here. With the serial numbers, I can switch between each of them and see the status and do even some adjustments. So if I fit the optical power again to the unit (as we've done before) the light turns green. And on the control unit over here the light was in blue transitional state, now it turned green.  So it mimics the LED that is on the unit. There are quite a few things you can control from the user interface. You can change the attenuation level, amplification level of the systems, but those will be covered in our next session.  Thank you for watching!"

Introduction to RFOptic Programmable RF over Fiber Solutions

RFOptic Programmable RF over Fiber Solutions Introduction.

Transcript: "Today we will be reviewing RFOptic's next-generation programmable RFoF solutions introduced earlier in the year. RFOptic's programmable RF over Fiber solutions come in three versions that operate from 500 kilohertz up to 2.5 GHz, 3 GHz, 6GHz and the version with Bias-T that supports GPS applications is also available.


As you can see, they all have the same small form factor. Now let's see all the components that make up an RFoF set. Each set is made of  Tx and Rx modules, 2 AC/DC adapters, fiber patch cable, 2 USB cables, and a USB drive. The T-module is used to convert radio frequency signals (that are input) to converter, to optical signal. The Tx module at the far end, is used to take in the fiber signal, optical signals, and output the RF signals. The patch cable is provided so that the user can test the units before a field deployment in their labs. The 3 USB cables are provided so that the user can simultaneously connect to both of the units from the data connectors. The user interface allows the capability to connect to both of the devices at the same time. Through the user interface, the user can modify the S21 system gain, the P1dB compression point, as well as few other parameters."
