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).

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.

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 compo-

nents. A further plus is the dustproof

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.

Functional and reliable

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.
