CHATSWORTH, Calif. -- MRV COMMUNICATIONS, INC. (Nasdaq: MRVC), a leading provider of Ethernet access solutions, today announced the first of its Photonic Air Link (PAL) series of all optical FSO systems - the Terescope 1. The TereScope 1 optical wireless system is the industry's first commercially available all optical free space optics system to deliver fiber-speed service without the need for electric power on the rooftop or opto-electronic (O-E-O) conversion through windows. TereScope 1 significantly reduces the cost of network deployment and speeds the seamless integration of next generation services for broadband access. The systems are passive, electronics and power independent units. Connected directly via fiber optic to an MRV switch module, the TereScope 1 system offers data rates of 1 to 100 Mbps, at distances of up to 300 meters. Protocol independent (SONET, Ethernet/IP, TDM, ATM and Cellular transmission), the TereScope 1 provides easy integration with any existing infrastructure, including twisted pair (DSL), CAT-5, fiber and wireless. Guy Avidan, vice president of MRV International, commented, "FSO equipment commercially available today are generally O-E-O (optical to electrical back to optical), which can impact the ability to scale a FSO system easily to ultra-high bandwidth capabilities. We have eliminated this barrier and the need for power on the rooftop or opto-electronic conversion through windows with the TereScope 1 and PAL series of all optical products. Easy to install and align, these systems can be deployed almost instantly to expand the customer's network as needed." MRV Communications Inc.
