Kathrein Extends its Range of Optical Compact Receivers
Designed for frequency ranges up to 1218 MHz in the forward path and up to 204 MHz in the return path, the receivers can also be used without restrictions in existing networks. The electronic frequency range changeover and the particularly high output levels allow step-by- step network upgrades to be implemented without problems. Outstanding intermodulation parameters and the lowest noise levels in comparison with their competitors ensure the best possible system characteristics.
The ORA 9224-1G2 and the ORA 9222-1G2 are highly-linear FttC fibre nodes for modular configuration, for use in HFC networks. They have two independent downstream paths as well as four or two independent upstream paths (each can be segmented). A double receiver and a single return path transmitter with constant light control permit full redundancy and segmentation. The modular concept allows the system specific configuration of the fibre nodes.
The optical compact receiver ORA 9022-1G2 with its platform strategy offers the same advantages as its “big brothers”. It can be used wherever one segment in the downstream and up to two segments in the upstream path are to be operated. The user can easily make all device settings via the WLAN module WTE 10 using the menu control of a mobile device such as a tablet PC or smart phone and a web browser. The new graphical user surface enables the clear and intuitive changing of all device parameters.
The latest GaN technology was used for all amplifier stages of the three receivers, thus offering very high output levels as well as superior dynamic data for all outputs. They are therefore ideally suited for use in Fibre Deep architectures with a passive coaxial distribution network.
