of interconnection cables — one at each end. The Laser Heads are installed
outdoors, where a clear optical path exists between the two sites. Each head is
equipped with heavy duty Alignment Base Unit, which allows exact positioning and
ensures reliable long-term operation of the system. The head assembly features rear
and front doors that provide easy access to the internal parts on the field during
installation, troubleshooting or upgrade procedures. Next to the head the Outdoor
Interconnection Unit provides fast and easy interconnection between the laser head
and the cable coming from the network equipment. Moreover the ODIU houses the
Power Supply Unit (PSU) of the system and the network interface. The PSU
provides the low voltage power required to operate the laser head while the data
port offers direct connectivity for standard network equipments. A variety of standard
copper and fibre interfaces are available for voice and data applications. The system
contains built-in signal monitoring unit, which features a visual signal strength
indicator and LINK status information accessible on the rear of the head assembly.
The optional IP Based Management Hardware is placed in an Indoor Interconnection
Unit (IDIU). The bar graph of the IDIU displays the actual signal strength level while
the LED indicators show the presence of Minor or Major alarm condition. With the
help of the relay contacts an external alarm monitoring equipment may be connected
to the system to process the alarm signals further .In addition to the above
GeoDesy-FSO GDview TM software allows the monitoring of the link’s operation
through a proprietary graphical interface (GUI) via Ethernet or RS-232 ports or a
third party SNMP manager via TCP/IP connection.
Industry standard network interfaces and clear upgrade path for higher bandwidth
protect the customer's investments in
GeoDesy-FSO systems. Moreover, GD-
2500 systems offer high level of network flexibility due to their modular design,
which makes them ideal to follow network topology changes.
2.7 GeoDesy-FSO GD5000 series
The
GD-5000 series products from GeoDesy-FSO
are laser based free space optical systems designed to
provide flexible, reliable and secure solution for high
speed wireless connections up to 5000 m. Due to their
modular design the equipments are easy and fast to
troubleshoot and upgrade on the field. Adjustable
transmitter optical system allows custom configuration of the system for specific
installations. The patented Aperture Control Mechanism delivers outstanding system
availability figures. The transparent and wire speed data transfer together with
virtually zero latency assures the easy integration of the system in all environments.
Furthermore,
GD-5000 series systems can be ordered with IP based SNMP
compatible device management that allows remote control and monitoring of the
equipment. Because they use infrared light as transmission medium,
GeoDesy-
FSO systems do not require frequency licenses and the transmission is not affected
by electro-magnetic interference. The concentrated laser beam is extremely hard to
tap, even to discover since it cannot be detected by spectrum analyzers. Basically, a
GeoDesy-FSO link can be considered as a virtual fiber in the air.
