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 IDU 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,
PRONTO systems offer high level of network flexibility due to their modular design,
which makes them ideal to follow network topology changes.
2.6 GeoDesy-FSO GD2500 series
The
GD-2500 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
2500 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-2500 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 fibre in the air.
The
GeoDesy-FSO GD-2500 systems comprise of two Laser Heads (each
containing four transmitters), two Outdoor Interconnection Units (ODIU) and two sets
