5. The current fiber optic backbone runs to central offices in most of the
large population centers in the US. There has been much work done
to upgrade the fiber optic backbone by both extending its reach,
and increasing its bandwidth. The high bandwidth capability of the
fiber optic backbone of 2.5 Gbps to 10 Gbps has been achieved by
improvements in switching and optical components, and with the
implementation of technologies such as wavelength division
multiplexing (WDM). Most of the recent large effort of digging up
the ground and laying down new fiber has been directed towards
extending the fiber optic backbone to new central offices, and not
laying fiber directly to the customer. In fact, only 5% of all buildings
have a direct connection to the fiber optic backbone.
However, more than 75% of all businesses are within a mile of the fiber
optic backbone.

8. Light up optical bandwidth for your next generation wireless networks.
Wireless mult-gigabit Ethernet links up to 8km
Lasercom has taken Free Space Optical (FSO) and wireless optical communications
a quantum leap forward in bandwidth, and distance. When AOptix resolved the random
unpredictable light scattering distortions caused by scintillation, the clear focus turned to
straight attenuation factors related to weather. Using real-time beam pointing and
tracking for tower twist and sway and collimated beam control for extended reach,
availability is significantly improved in severe weather conditions.
Lasercom offers wireless networks the capacity equivalent of fiber cables. Whether it is
multi-gigabit terrestrial links or secure private networks, the unique set of product
features built into each of the AOptix products ensures top performance.
Key features:
•Long distance links for wireless backhaul up to 8km.
•Scalable capacity to 10 GigE & beyond.
•Real time compensation for tower twist & sway.

9. Breaking the Bandwidth Bottleneck
AOptix lasercom terminals provide solutions for backhaul aggregation hubs, loops, edge and metro
rings, as well as enterprise LAN's between buildings and sites. The bi-direction high capacity links can
also support fiber-backbones as extensions or as emergency back-up links. The interference-free
operation provides true fiber equivalent performance for multiple applications.
The low profile, long distance, high capacity attributes of Lasercom offers diversified solutions for low
profile pico-cells at street level, long distance backhaul aggregation hubs on towers, and high capacity
metro rings on building rooftops.
The outdoor unit (ODU) requires 1 linear foot of tower space regardless of the required capacity. As
network demands increase, this unique product will continue to provide the best value, cost per Mbit
solution year after year.
Availability is the performance measure for Lasercom:
Precision real-time active beam pointing ensures link stability under the worst case twist and sway
conditions for utility poles, towers and building rooftops
Pre + Post Correction for atmospheric distortions caused by scintillation
Collimated Beam control for longer distances in severe weather conditions
"Total Cost of Ownership" (TCO) is the financial measure for Lasercom:
Small lightweight ODU includes semi-automatic link alignment for ease of installation
Low profile configuration and energy efficient power rating ensures the lowest operating costs
Hitless capacity upgrades support new services without building additional infrastructure
The new wireless Lasercom links backhaul multi-gigabit Ethernet payloads in either direction. This cost
effective solution eliminates fees for leased fiber, spectrum licensing, as well as building permits and
construction costs for trenching fiber or additional wireless towers.

10. Laser Links 1.5 Mbps to 10 Gigabit speeds
What is a Laser Link or FSO? Free-Space Optics (also known as FSO,
Wireless Optics or Optical Wireless) is an optical data, voice and
video transmission system. Like fiber optic cable, wireless optics
communication systems use laser light to transmit a digital signal
between two transceivers. However, unlike fiber, the laser like is
transtmited through the air (free-space) instead of through a glass
strand. In order for the digital signal to be transmitted and received,
there must be clear line of site between each wireless optics unit. In
other words, there should be no obstructions such as trees or
buildings between the transceiver units.
