History of Free Space Optics (FSO) Selenium
"It's the greatest invention I have ever made; greater than the telephone!” - Alexander Graham Bell 1880 • tests over 200 meters were successful • Since sunlight was used as the source, only worked during sunny daytime hours •– now we use lasers…much better! www.mrv.com

RF Backup Example 2.4GHz RF Backup system • ISM Band frequency • Licence free • RF offers 11Mbps • Switchover <1s • Greatly increases availability - useful in foggy areas T1000X with fusion backup
www.mrv.com
Other Wireless Technologies (1) ISM Band - Spread Spectrum Radio • 2.4GHz "unlicensed" frequencies • Short to Medium range point-to-point or point-to-multipoint systems • Internal or external applications • Limited to throughput of 11 Mbps (Half Duplex) • Data security implications • Bandwidth (speed) is very limited for large projects or if the area is RF crowded. www.mrv.com
Other Wireless Technologies (2) Licenced Microwave •
Use for longer distances (above 1km)
• •
High data rates are available High availability figures at long range
•
Complex installations with link-engineering required Public & Local Auth. safety concerns Hard to obtain frequency licences for distances under 1km

MRV Communications Free Space Optics technology TereScope Passive FSO FAQ
Applications – New Developments
www.mrv.com
Point-to-Point Applications For most users, the TereScopes are an easy and cost-effective way to connect a remote building to their network. This allows immediate access without paying monthly leased-line fees.
www.mrv.com
Ring Applications In a multi-building campus environment, TereScopes can complement your existing network infrastructure by reaching buildings not already on your fiber or providing back-up to your fiber for added redundancy.
www.mrv.com
Access Mesh Topology For carriers and ISPs, TereScopes can be used in a mesh topology to reach multiple customers and maintain routing flexibility. This allows a ‘pay-as-yougrow’ deployment strategy and always maximizes network uptime.

Case study Ministerie van Verkeer en Infrastructuur Brussel Employees are divided over three different buidings in Brussels: – – –
Residence palace Aarlenstraat Cabinet
Initially the communication between the three buidings are made via ISDN-routers. The ministry was searching for a more cost-effective solution
www.mrv.com
Case study Ministerie van Verkeer en Infrastructuur Brussel Requirements: One link between the Residence Palace and the Aarlenstraat – Distance 550 meter – Protocol Fast Ethernet (100 Mbps) – Must have RF backup
Second link between the Aarlenstraat and Cabinet – Distance 90 meters – Protocol Fast Ethernet (100Mbps) – No backup requirements

Case Study: Press Ganey No Line of Sight In this Fast Ethernet enterprise application, no line of sight existed between the two buildings. This problem was overcome by using two TereScopes to connect the buildings via an intermediary point. The two links were 180 m and 335 m in distance, and have plenty of margin to overcome the elements in South Bend, Indiana.
www.mrv.com
Case Study: Netune Communications Movie Production In this temporary application, a TereScope 1000X was used to connect a multimedia studio to the private workshop of a visual effects editor. Operating in London, England, the TereScopes spanned a distance of almost 1 km to provide Fast Ethernet connectivity between two switches. The project was a complete success and the units are being used by the company in other temporary applications.
www.mrv.com
Case Study: TereScope 1 (PAL) in Paris The TereScope 1 (PAL) systems have the advantage of not requiring electrical power at the unit. In this application, these all-optical units were used to connect a Fast Ethernet hotel data network over a distance of 150 m. The units get their optical signal directly from special modules in an OptiSwitch, which can also be used as the network switching platform. This combination of products made for a quick and cost-effective connectivity solution.
