A Short Introduction to RFOptic and Its Solutions

Posted on by admin

RFOptic is a leading provider and vendor of RF over Fiber (RFoF) and Optical Delay Line (ODL) solutions as well as embedded RF Optical solutions for OEM customers in the telecommunications, aerospace & defense, broadcasting, and infrastructure industries.

RFOptic is known for its RFoF links, multi-link / multi-channel RFoF systems and subsystems to meet customer requirements, including diverse enclosures (indoor and outdoor), and supporting multiple RFoF links with monitoring and management capabilities. RFOptic’s RF over Fiber solutions offer the best cost performance ratio, featuring noise figure of 5dB and gain link of around 40dB.

The programmable low frequency RF over Fiber units (0.5MHz to 6GHz) are based on direct modulation. The MiniQ High SFDR series indirect modulation product family supports applications from 10MHz to 40GHz with low noise and high spurious-free dynamic range (SFDR). RFOptic’s Optical Delay Line solutions are available as “fixed” ODL with up to 8 predefined time delay values in a single unit, or as “variable” supporting up to 255 delay states. All Optical Delay Lines feature delays of up to 250 μsec (>250 μsec upon request) while maintaining excellent performance. Customers can add RFoF functionality with RFOptic’s compact OEM board for high volume requests. The company’s unique software communicates with our programmable RFoF units, offering you unparalleled flexibility for you RFoF or ODL deployments.

In addition, RFOptic also develops, integrates, and delivers the most cost-effective and state-of-the-art product development of mixed microwave and optical solutions to companies worldwide. The company’s extensive experience and know-how overcomes the technological challenges which customers face, from original concept up to production.

The procedure for customized solution consists of 5 steps from request to implementation:

  1. Getting the requirements from the customer
  2. Building the concept
  3. Defining the specifications and setting the budget
  4. Building a proof of concept for approval
  5. Going into serial production

RFOptic has launched its high frequency links with ultra-low spurious level for RADAR and EW applications

Posted on by admin

At the request of customers, RFOptic has now launched 12GHz, 18GHz, 20GHz, 30GHz, and 40GHz RF over Fiber links that have an ultra-low spurious level of less than -95dBm. This means that RFOptic’s MiniQ RFoF series provide spurious-free dynamic range (SFDR) better than -112dB/Hz. Spurious RFoF solutions are essential in order to mix non-harmonic spurious signals with the input RF signals at the output of the RFoF link. The spurious signals increase the Probability of False Alarm (PFA) and Minimum Detection Signal level (MDS) for EW and RADAR systems and degrade the Adjacent Channel Power Ratio (ACPR) in communication systems.

On a technical level, achieving extremely low spurious levels is a major challenge, particularly in small and tight RFoF modules where power consumption must be kept as low as possible. Many applications can only be supported by a design that achieves low spurious levels across extremes of the RFoF link bandwidth. Applications such as Optical Delay Lines, used in many RADAR test ranges, require ultra-low spurious to test and optimize extremely sensitive systems.

Thanks to the efforts of RFOptic’s R&D department, the new offering will achieve this critical parameter, which opens the market for RADAR and EW as well as other applications.

In general, a high spurious-free dynamic range (SFDR) is desirable when multiple signals of very different power levels are expected to coexist. A high SFDR RFoF solution simplifies signal conditioning requirements that are required to separate true signals from the unwanted spurious. There are well-known techniques, which are intended to identify the spurious signals and null them including LO dither, adjustable ALC, and power range stepping.

However, these techniques complicate the extraction of the real signals of interest and require extra signal processing, which now can be reduced or re-directed to deal with the real input signals rather than with artifacts of the RFoF link. During antenna, RADAR, or communications system testing, high SFDR is essential due to the typical large signal amplitude ratios between main and side lobes or between close and distant targets. The same applies to DF/ELINT systems, which have to handle strong jammers concurrent with weak signals of interest.

RFOptic’s Unique Software Helps Customers to Configurate and Control Their RFoF Modules

Posted on by admin

As RFOptic, we always strive to bring our customers of our RFoF and ODL solutions the best service and support in the field. That’s why we have developed unique software that allows you to configurate your RFOptic’s RFoF modules.

With the software, you can control one or more modules. All you need to do is to power up and connect your computer or tablet using a standard USB to interface with the software. Once connected, the software detects your RFoF modules, and you are ready to configurate and control them. The software is designed to work on PCs and laptops that run Windows 7, 8 or 10 operating system versions. Please note that it does not operate on previous operating system versions. However, a separate version for Windows XP. Is available. The software detects the modules automatically once connected.

Some of the features include:

  • Connecting Transmit (Tx) and Receive (Rx) RFOptic’s RFoF modules
  • Simultaneously connection to multiple modules
  • Obtaining status information and verifying the optical connection
  • Setting up and operating the configuration
  • Defining power-up default setup
  • Initiating self-test, RF module test and RF link test

With the software, it’s easy to check if your modules are connected correctly. (See also our video to learn more) The panel LED indicators on the RFoF modules will indicate if the optical fiber is connected or disconnected.

  • If the optical fiber is disconnected, the panel LED of the Tx is green and the panel LED of the Rx is red.
  • If the optical fiber is connected properly between Tx and Rx units, the panel LEDs of both Tx and Rx are green.

The image below illustrates the easy-to-use software offering a rich set of features and functionalities.

The software is made available free of charge under the license agreement, please make sure to familiarize yourself with the content before downloading and using the software.

RFOptic at IBC 2017

Recently, RFOptic attended the IBC 2017 to meet existing and new customers, strategic partners and distributors. Since we are a leading provider of RF over Fiber & Optical Delay Line solutions, it was a given that we would be attending this world’s leading media, entertainment and technology show.

The IBC 2017, which celebrated its 50th anniversary, was highly successful with a record attendance of over 57,000 visitors. The IBC Exhibition covered fifteen halls across the RAI Exhibition and Convention Centre in Amsterdam and hosted over 1,700 exhibitors spanning the creation, management and delivery of electronic media and entertainment.

At the event, RFOptic had 45 meetings with AV and Satcom integrators as well as wireless cameras and microphones companies who showed an interest in our RFoF and ODL solutions that are already used by Tier 1 and other enterprises active in the broadcast, audio and video sector as well as in the telecom, aerospace, governmental, and research labs industries.

We also introduces our two recent offerings:

  1. Our innovative compact bidirectional (2 way) RF over Fiber (RFoF) transceiver which is comprised of an uplink of Tx and Rx (at 1550nm) and a downlink of Tx and Rx at 1310nm, and
  2. Our controllable RF over Fiber (RFoF) OEM cardswhich offer an excellent solution for companies who need to add an RF over Fiber capability to their portfolio.

We also met potential distributors and integrators for strategic partnerships and cooperation, and met several of our competitors to discuss mutual interests.

We will be attending the next IBC, so come and meet us again at the IBC 2018 that will take place September 13-17, 2018 in the RAI Exhibition and Convention Centre in Amsterdam.
