Customized systems

RFOptic routinely provides semi and fully customized solutions that are based on RFoF technology. These solutions are engineered using existing standard products, including required adaptations and optimizations as needed to address customer requirements and applications. We’ve successfully produced turn-key complete systems and subsystems as well as custom RF Over Fiber (RFoF) products for customers in many market segments, including cellular communications, 5G/6G testing, and EW/Radar/Satcom defense markets. For a proposal, please go to RFQ for subsystems.

Customized ODL and Altimeter

Optical delay lines (ODLs) and Altimeter Optical Delay Line (ALT ODL) have a wide range of applications as test instruments. These ODLs may also be used as system components and tend to have specialized requirements. RFOptic provides an online form to streamline requests for ODL systems. It is structured to provide guidance for many options, standard features and parameter values. This form generates a concise definition of the required custom ODL solution that enables us to design the system, simulate its performance, and provide a reliable technical specification.

Optical Up/Down converter

RFOptic has developed wideband frequency conversion-based RFoF products useful for special applications. Frequency converted RFoF links provide low-cost solution for mm‑Wave sub-band RFoF links. Optical RFoF frequency converters allow coherent wideband frequency conversion. This special technology is ideal for EW applications and airborne platforms.

Redundant multilink products

RFOptic supplies many high-reliability RFoF systems, which include redundant RFoF links as well as redundant power supplies. Redundant RFoF links include a pair of RFoF links, a main channel, and a backup channel that together form a redundant group. To ensure uninterrupted transmission of the signal, the redundant group includes an automatic switchover to a standby RFoF link if the main RFoF link fails or its fiber connection is broken. In this way, superior and reliable performance, superior to that of a coaxial cable interface. A typical redundant system is composed of 2 or 4 redundant auto-switch RFoF channels that are connected to each other by independent, individually routed single-mode fibers (SMF). Such systems are often procured for broadcast services and to support 5G cellular band backhaul.

Drone and robotics products

RFOptic offers several RFoF solutions for remote-controlled platforms. These solutions include bi-directional RFoF links for control station antenna remoting with the aim to distance the source of RF emissions for operator crew safety and to achieve improved antenna coverage. RFoF links used for these purposes are specialized and include one or more power amplifiers and are fitted with appropriate limiters to handle potentially high reflected RF power. These systems can be configured with a single RF port on the controller side, and a bi-static antenna configuration on the remote side and can be enclosed in indoor or rugged outdoor enclosures. Where the controller can be shielded from the Remote antenna site it is possible to make the RFoF link communicate wirelessly with controller(s) allowing for different controllers to use the same RFoF remote antenna link.
