Free Space optics
ECSYSTEM Free Space optics (FSO) provides higher capacity Point-to-Point connection with capacity up to 10 Gigabits Full Duplex The Free space optics (FSO) equipment uses lasers to transmit data, but instead of enclosing the data stream in a glass fiber, it is transmitted through the air. It is a secure, cost-effective alternative to other wireless connectivity options.
Application area of Free space optics 
Mobile and fixed link
-
Connecting of base stations. Backhaul for LTE network
- Internet service provider success-story-fso-czech-republic.pdf
-
Continuous growth of base stations numbers and services require a significant communication channel capacity increase. Using FSO equipment, which does not require any radio frequency authorization, easily solves this problem. Besides, availability of multiplexers with E1 channel in our production line allows transmitting in parallel via one transmission link from 2 to 24E1 data flows and Ethernet traffic, which saves investments in the network channel terminating equipment.

It is the only Modular System currently available in the market: The Free space optics EL-1G with throughput 1Gbps and the FSO 10Gbps with capacity 10 Gigabits, which can be with option of posible upgrade of throuthput up to 30Gbps. This upgrade is possible without the need to replace the Unit. This also means there is no realignment required after the upgrade is completed bringing downtime to its barest minimum.
Real-time AGC (Automatic Gain Control) is used in every model to regulate the optical transmit power of the laser diode depending on the link quality which is constantly monitored. This is to ensure high availability of the transmitting circuit.
Real-time Auto tracking is used in every model to compensate for thermal expansion that occurs as a result of mast and building movements.
Internet - creation of high speed local area network of "star" or "ring" topology as well as to realize network development and connection to other networks.
Security systems - Wireless optical communication is one of the most effective options for security and safety systems which provides high data transfer rate. The laser beams are very narrow so it is almost impossible to intercept them.
Network infrastructure - The equipment ensures a quick formation of a wireless optical communication channel when combining the existent region communication channel with already finished network.
Data transport networks - Gigabit Ethernet, ATM, FDDI, Fast Ethernet, Ethernet
