PAV Data Systems - Free Space Optical Systems for Optical Wireless Communications

PAV provides free space optics systems – FSO - to enterprise and service providers worldwide, supplying last mile connectivity for voice and data communications and wireless backhaul.

PAV Data Systems began as an optoelectronics specialist in 1990, focusing on FSO technology, and has developed into a provider of FSO communications solutions that provide high bandwidth connectivity using lasers or LED-based technology operating in the near infrared spectrum.

LICENSE-FREE OPTICAL WIRELESS LINKS OFFER SERVICE PROVIDERS LOW COST CONNECTIVITY

The last mile connection from a fiber optic network can use PAV's FSO laser links cost-effectively where there is line of sight up to a maximum of 4km. The license-free aspect is attractive to operators offering alternatives to fiber optic links and microwave – as well as 802.11 radio RF.

FREE SPACE OPTICS (FSO) IN ENTERPRISE NETWORKS

FSO is becoming a mainstream technology delivering high bandwidth connectivity for data, voice and video. More internet protocol – IP-based traffic, including Voice over IP – VoIP - is being transmitted across data networks as more broadband connections are established. This last mile connectivity is used frequently on campus sites where point-to-point, building-to-building data links are required.

HIGH BANDWIDTH FREE SPACE OPTICS (FSO)

Bandwidth solutions covering 10Mbps Ethernet, 100 Mbps Ethernet – FET Fast Ethernet, Gigabit Ethernet, ATM155, ATM622, E1 and n x E1 for data, voice and video can be fully integrated over an FSO laser link offering broadband solutions at wireline speeds. This covers 10Base-T, 100Base-Tx and 1000Base-Sx/Lx.

Point-to-point links have been the traditional applications for FSO, but now more companies are installing resilient networks using either ring topology, star topology or mesh topologies incorporating SDH and PDH.

FREE SPACE OPTICS FOR LAN-TO-LAN COMMUNICATION

FSO links from PAV provide full duplex connectivity, providing Gigabit Ethernet speeds for high bandwidth applications while retaining data security required for the corporate LAN – Local Area Networks, WAN - Wide Area Networks, or MAN - Metropolitan Area Networks.

Free space optics can provide the high bandwidth network infrastructure which supports the latest technologies including Wi-Fi and bluetooth as well as the Wireless LAN – wlan. This enables service providers to supply GSM mobile-based hotspots for wireless IP connections.

Free space optical technology overcomes the security issues facing unlicensed radio 802.11 RF and microwave technologies.

FSO can operate over relatively long distances in urban environments for LAN-to-LAN communications, providing office-to-office connections on campus and factory locations where line of sight, LoS, is usually available. Traditionally, expensive leased lines have been used from telco operators as well as costly fixed cabling, licensed microwave or IEEE 802.11 radio systems which may develop spectrum availability or security issues.

Free space optical networks provide cost effective, license free, high bandwidth, rapidly deployed communications links to overcome these issues.

BROADBAND INFRASTRUCTURE

FSO can provide the backbone network, access network and resilient paths by line of sight, LoS, which includes services for Ethernet, 10BaseT, Fast Ethernet 100BaseTx, Gigabit Ethernet, 1000Base Sx/Lx, ATM155 – 622Mbps, and n x E1 (G.703).

BUSINESS CONTINUITY AND FSO

Disaster recovery has become an important factor in business survival and free space optics is now a tested method of providing instant infrastructure. High bandwidth connectivity can be restored in hours to back up fiber optic networks and ensure business continuity.
