4 4 I KOBRA I System overview KOBRA Optical broadband platform In the form of the KOBRA system Kathrein offers a comprehensive broadband platform that covers all the requirements of optical transmission. A wide range of modular optical transmitters, amplifiers and return path receivers is supplemented by separate device in 19" rack-mounting form. The basis for this is the KBP 4000R 19" broadband platform with a total of 16 module slots. It is already equipped with two redundant power supply and fan units for reliable operation. The scope of supply also includes a plug-in control unit with LC display, status LEDs and input buttons. In the rear part of the platform a bus system provides for the connection of the modules to the 24 V DC power supply, the RS 485 remote monitoring and control interface and management via the control unit. The broadband platform uses four height units and can also be adapted for ETSI cabinets. When used in hubs, for example, the broadband platform can also be used in a 48 V DC version (KBP 4048R).

5 KOBRA I System overview I 5 Comprehensive management and monitoring options permit flexible and reliable operation in any network configuration. The plug-in control unit supplied in the basic configuration can make all the settings required by the equipment. The network element controller module Ethernet (NCM 10) plays a central role here. On the one hand, it sets up the connection from the control unit to all plugged-in modules via the RS 485 bus. One NCM 10 can manage up to three fully equipped KBP 4000R or 4048R broadband platforms. On the other hand, it converts the RS 485 data into SNMP/ Ethernet and Web browser/ethernet protocols. In this way all settings and queries can also be handled by a PC with a Web browser. In addition, it is possible to integrate the broadband platform into any HMS-compliant monitoring system, such as the KOM communication system from Kathrein. Together with the optical compact receivers from Kathrein, an optical distribution system that meet all requirements can be set up with the KOBRA broadband platform. As a result of the modular design and the wide-ranging selection of products that are available, all application cases ranging from a simple optical connection via classic HFC structures up to video distribution in FttH networks is possible and economically viable. Kathrein constantly develops its products further and expands its range of products. Further product variations are available on request. Features in overview Optical broadband platform for up to 16 modules Equipped with two redundant power supply and fan units Large selection of optical transmitters, amplifiers and return path receivers All optical and electrical connections at the rear panel, test sockets at the front panel Integration into any HMS-compliant monitoring system is possible Plug-in control unit with LC display, LEDs and input buttons Settings and management also via a Web browser RS 485 remote monitoring and control interface Management of multiple optical broadband platforms with one controller module is possible Automatic redundant operation of adjacent modules High reliability due to dust-tight modules and large cooling ribs Versions with mains voltage ( V AC) and direct current (36-72 V DC) Note: All data are typical values, unless stated otherwise. Installation height/construction: 19" rack with four height units (HU)

6 6 I KOBRA I System overview Functional and reliable Front view Rear view Platform The KOBRA optical broadband platform has a carefully thought out operation and management concept. Power supply units Redundant power supply units, in each case with duplicated fan units, ensure high reliability. If servicing is required, it is even possible to replace the power supply units even while the unit is running. Network element controller The central element is the network element controller Ethernet NCM 10. This module forms the interface to the RS 485 bus to which all the modules of the platform are connected. In addition, it sets up the connection to external management or monitoring systems, for example, via a Web browser or to HMS monitoring devices. In the last resort, it makes possible the local setting of all parameters via the control unit with the display and input buttons. The corresponding data is kept in decentralized form in the individual modules so that they can also be operated completely independently without the controller module after the commissioning Modules Slimline modules that in some cases have a double functional scope (e.g. return path receivers) ensure a high packing density. The small amount of space required increases the economic viability and makes it easier to expand later. The optical amplifiers only require two or three slots despite their very high output power. Test sockets All the test sockets are located on the front panel. This ensures good accessibility for tests and measurements. HF interfaces The optical and HF interfaces are located at the rear panel of the platform. This makes the wiring in 19" cabinets significantly easier. Cooling ribs Generously sized cooling ribs ensure a long working life for all active components. A further plus is the dustproof 7 configuration of all the modules. The cooling air only flows along the cooling ribs but not through the module itself. This virtually excludes any problems due to dust and dirt.
