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.
