Transporting RF signals over fiber optic cable has distinct 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 CWDM Multi RFoF and GbE Data Channel Link is housed in a fixed configuration of EIA 310-D Standard 19 inch 1U rack mounts. The Link is capable of providing long or short distance uplink/downlink solutions that may be achieved using our cost effective isolated CWDM DFB Lasers while more demanding long distance or multi-carrier CWDM applications may be met using our wide dynamic range cooled DFB Lasers – delivering excellent signal quality under varying conditions.
