Lynx Photonic Networks unveils nanosecond class photonic switch

Mar. 12, 2001--Lynx Photonic Networks, a developer of patented planar waveguide photonic switches and subsystems, is announcing its new dynamically controllable nanosecond class switch.

Lynx Photonic Networks, a developer of patented planar waveguide photonic switches and subsystems, is announcing its new dynamically controllable nanosecond class switch.

The Packet.4x4(TM) has four input ports and four output ports, a switching time of less than 5 nanoseconds, and features strictly nonblocking (anywhere-to-anywhere) operation.

This ultrafast, dynamically controllable, intelligent switch enables virtual port expansion of previously limited high-speed communications systems, such as 10 gigabit Ethernet switches, high- speed routers and OC-192 SONET multiplexers. These applications are accomplished by overcoming the bandwidth and data rate limitations of the existing backplanes of such systems.

One application example would be the creation of multi-terabit router systems through the interconnection of four or more terabit routers. Other application examples include inter- and intra-shelf connectivity, storage area network (SAN) switching and, in the future, all-optical frame and packet switching.

The Packet.4x4 can transparently switch photonic bit streams in either the 1300nm or the 1550nm spectral windows. The product provides for data rate, protocol and data format transparency. Its high-speed logic interface enables unique capabilities, such as integrated optical multicast/broadcast capabilities. In addition, there is less than 6dB insertion loss fiber-to-fiber with no measurable bit error rate.

The Packet.4x4 utilizes an almost instant electro-optic switching technology based on Lynx's Planar Lightwave Circuit (PLC) design, intelligent optical path control and proprietary packaging.

The optical chip is fabricated on a Lithium Niobate substrate, assembled on a printed circuit board (PCB) with on-board intelligence, and fully integrated into a compact 19-inch, 1U rack mountable housing, with high-speed logic control interface. It has been designed for robust handling and is based on long-established volume manufacturing processes.

The Packet.4x4 will be demonstrated at OFC in Anaheim, Calif., from March 19 to 21, 2001. Visit the Lynx booth, No. 3244, for a demonstration of the product.
