LaserBit ATM Series
 The ATM155 range of LaserBit offers cost effective, reliable and secure laser based optical transmission for voice, data and video through the air at 155 Mbps. The laser transmission carries the data using the concentrated laser beam and a unique modulation technique is employed to ensure error free data transfer over distances up to 5000 meter.
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 environment. Because they use infrared light as transmission medium, LaserBit systems do not require frequency licenses and the transmission is not affected by electro-magnetic interference. The laser beam is extremely hard to tap, even to discover since it cannot be detected by spectrum analyzers. In order to capture the transmitted information, the tapping device must be in the beam, precisely aligned, which in most of the cases is impossible and any tryout can be easily detected. Basically, the LaserBit link can be considered as a “virtual” fiber in the air, which ends in a “real” fiber optic cable at both ends.
The LaserBit system comprises of two Laser Heads – one at each end – and the associated supporting hardware. The Laser Heads are installed outdoors, usually on the rooftops or sidewalls of the buildings where a clear optical path exists between the two sites. Next to the head the Outdoor Interconnection Units (OIU) provides fast and easy interconnection between the laser head and the cables coming from the network equipment. Moreover the OIU houses the Power Supply Unit (PSU) of the system, which provides the low voltage power required to operate the laser head. The system contains built-in signal monitoring unit, which features a visual signal strength indicator and LINK status information accessible on the rear cover of the head assembly. The optional Indoor Interconnection Unit contains the Alarm and Monitoring Unit (LB-ALARM-MON) or the IP Based Management Hardware (LB-MGM). The bar graph of the LB-ALARM-MON 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 further process the alarm signals. In addition to the above the LB-MGM allows the monitoring of the link’s operation through a PC-based software (LaserBit View) via Ethernet or RS-232 ports.
