MRV is the leader of Free Space Optics (FSO or Optical Wireless or Laser Link) with the TereScope® product line, an optical wireless system for data, voice and video transmission system. With over 8000 links deployed worldwide, MRV has more experience installing and servicing this equipment than any other Optical Wireless vendor. The MRV TereScope® Laser Link systems provide the most comprehensive FSO wireless solutions, ranging from short to long distances and narrow to ultra-high bandwidth.

What is FSO? Free-Space Optics (also known as “FSO”, “Wireless Optics” or “Optical Wireless” Laser Link) 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 Laser Link transceiver units.

How is Free-Space Optics Deployed?
Wireless optics systems are typically mounted on the sturdiest areas of buildings or other structures, where there is minimal exposure to vibration, wind sway, and thermal expansion. Usually the corner of a building's roof is the best location, or as close as possible to an outside wall. Mounting to masonry is preferred, as wood is very susceptible to moisture expansion. Wireless optics units can also be installed indoors behind a window.
 
FSO systems typically interface with your network switch, hub, bridge or router via multimode fiber (850nm or 1310nm) and standard ST or SC connectors. Some TereScope products also connect directly to copper interfaces. The network configuration is designed as if the FSO link was a fiber optic cable running between multiple sites. Free-Space optics systems can be protocol transparent or locked to a particular protocol depending on the user’s needs. A variety of SNMP and proprietary management options are also available for wireless optics systems.

The TereScope™ family of Free-Space Optics (FSO Laser Link) products provides low-cost, high-speed wireless connectivity for a variety of last-mile applications. Operating at data rates of 1.5 Mbps to 10 Gigabit speeds, TereScope systems are deployable in one day, without requiring right-of-way or government permits for installation, providing communication links in hours instead of weeks or months.

• Leased line replacement or backup
• High bandwidths available up to 10 Gigabit
• Licence free operation
• Cost effective solution
• Rapid deployment – less than a day
• Immune from interference

MRV TereScope Laser Link Series Comparison

TereScope TS700 up to GE and 400m

The TS700 series provides high speed Free Space optics (FSO) connectivity for a variety of first mile applications. Operating at full wire speed data rates of 1 Mbps to 1.25 Gbps, the TS700 series is rapidly deployable, without requiring right-of-way or government permits for installation, providing you with communication links in hours instead of weeks or months.

The TS700 is a high quality product specially designed for short distance connections reaching distances of up to 400 m at the best price performance ratio possible.

TereScope® 2000 systems, like all TereScope units, are deployable within a matter of hours. TereScope 2000 supplies a connectivity that reaches up to 4.1 km and supports various protocols. The TS2000 has two transmitters and an 8” RX lens - these features almost eliminate any scintillation influence and en¬hance the transceiver’s reliability. The TS2000 is especially recommended for Voice Connectivity - E1/T1 & 4x E1/4T1 solutions even for short distances.

TereScope TS2000 up to Gigabit

The carrier class TereScope® 2000 operates at data rates of 2 Mbps to 1.25 Gbps. TereScope 2000 systems are used for medium distances and support a wide variety of protocols at full duplex at wire-speed. The more popular protocols are supported, but the power supplies and interfaces are not modular (unlike the TS4000 and TS5000), and a more compact aiming head is used, to reduce system cost. This balance of a basic set of features with multiple transmitters and a large aperture receiver in the large form factor offers a lower cost solution while still maintaining the increased robustness of the large form-factor links.

The TS2000 is especially recommended for Voice Connectivity - E1/T1 & 4x E1/4T1 solutions even for short distances.

TereScope TS5000 up to Gigabit

The carrier class TereScope® 5000 provides long distance high-speed Free Space Optics (FSO) connectivity. Operating at data rates of 1 Mbps to 1 Gigabit, TereScope® 5000 systems are deployable rapidly, providing long distances FSO optical wireless connectivity.

TereScope® 5000 uses multiple transmit aperture technology (3 transmitters) to ensure high performance in adverse weather conditions. The receiver of the long-range TereScope® 5000 has an 8” diameter to overcome scintillation and other atmospheric noises in hot or cold weather.

The TS5000/100-F is designed specifically for 100BaseTX applications, and features a copper RJ45 interface, for both the main interface and redundant FUSION output. For this model the Fusion feature is standard. This model in the low voltage version (V3) has a High Power over Ethernet (PoE, 30W) configuration. The TS5000 series also has a modular interface, i.e. the transceiver can be easily modified in the field from multimode to singlemode or from 850 mm to 1300 mm. (available in TS5000/155, TS5000/155-F, TS5000/G and TS5000/G-F models). An additional advantage of the transceiver modularity is the possibility to add the Fusion option in the field in case this option has not been previously purchased.

TereScope TS-10GE up to 10 Gigabit

TereScope® TS-10GE, the industry’s first wireless 10-Gigabit Ethernet system. TereScope TS-10GE has a range of up to 850 meters in clear weather. It connects to the LAN using a XFP interface with physical-layer and wavelength flexibility and distances up to 10 kilometers.

TereScope® TS-10GE product due to be released 2009! So watch this space.
