Optical Zonu’s RF over Fiber Optics stand-alone transceivers are used as In-Building (DAS) fiber optic transport links. Its broadband capability allows any type of Radio Frequency (RF) signal within the range of 30 MHz to 3 GHz to be transported reliably over single mode or multimode fiber optic cable. Typical DAS applications utilize our products to create bidirectional point-to-point, or point-to-multi-point, links between signal sources and the head end location where the DAS equipment is located. Signal sources include, but are not limited to, 800MHz Cellular, 800MHz or 900MHz iDEN, 850MHz CLR, 1800 and 1900 MHz PCS, 1700 to 2100 MHz AWS, 3G and UMTS, as well as, 2.4 GHz (WiFi and WiMax) and all public safety and UHF and VHF bands.
Optical Zonu’s standard products have a bandwidth ranging from 30 MHz to 3 GHz, and come with a manual gain control (MGC) capability for ease of installation. This makes them ideal choices for virtually all in-building (DAS) applications, especially compared to competing narrowband-only converters.
Transporting RF signals over fiber optic cable has advantages over using coax cable particularly for longer distances. Coax cable has a significant amount of signal loss over longer cable runs limiting its application for long distance links. High quality, low-loss coax is very bulky and expensive. Coax cable often has a large diameter, making it very inflexible and difficult to manipulate. Optical fiber supports very long cable distances, up to 10 Km or more, with minimal signal loss and degradation. Optical fiber operates by transmitting light along a dielectric glass fiber, rather than electrical signals over copper wires. This provides a highly secure, tamper-proof medium for signal transfer, minimizing security risks and unauthorized signal interception concerns. Light is also unaffected by electro-magnetic interference, allowing signals to be transmitted unaffected through electrically noisy environments.
Optical Zonu’s RF over Fiber products for In-Building (DAS) applications come in several different form factors. Stand-alone transceivers, fixed or modular configurations and EIA 310-D Standard 19 inch 1U sub systems are available. All our RF over Fiber Optics Links are capable of providing long or short distance uplink/downlink solutions which may be achieved using our cost effective isolated Fabry Perot Lasers, while professional and more demanding longer distance or multi-carrier CWDM applications may be met using our wide dynamic range, regular or cooled DFB Lasers – delivering excellent signal quality under varying conditions.
