APRIL 7, 2008 -- PacketLight Networks Ltd. (search for PacketLight) has released the PL-1000, which it asserts is the first connectivity platform for dark fiber and WDM networks to provide four services at 10 Gbits/sec each in a 1U box.

The PL-1000 is designed to provide 10-Gbit/sec connectivity over existing dark fiber infrustructure previously used for lower-rate services by providing integrated optical amplifier (EDFA), 3R functionality, and mux/demux. The PL-1000 also is designed to offer carrier-class functionality, including built-in performance monitors, protection, and regenerator mode within its compact frame.

The PL-1000 is designed for several network applications, such as upgrading existing CWDM networks to support 10 Gbit/sec connectivity. The PL-1000 supports both CWDM and DWDM optical links based on standard XFP technology. Furthermore, the PL-1000 chassis can be cascaded and integrated with PacketLight's PL-400 and/or PL-300 to provide scalable transport for 32 or more services starting from 2 Mbits/sec up to 10 Gbits/sec. The PL-1000, which is typically deployed as customer-located equipment in enterprise campus environments and central offices, is also environmentally friendly with its low power consumption, the company adds.

"The PL-1000 is the most advanced 10G connectivity solution of its size." said Koby Reshef, PacketLight's vice president of marketing. "The PL-1000 addresses the growing market need for 10G connectivity over the existing fiber infrastructure, leveraging fiber utilization and capacity significantly. Our new product fits perfectly to provide high-throughput metro Ethernet connectivity; effective infrastructure for triple-play, NGN, and DSLAM backhaul; and enables upgrade of existing CWDM or DWDM networks to support 10G services."

The PL-1000 supports a variety of services such as 10GBase-R, 10GBase-W, STM-64/OC-192, 10G FC, and OTU-2 in any mix. Two out-of-band optical supervisory channels are provided for HTTP- and SNMP-based management. The PL-1000 contains built-in passive optical filters (mux/demux) and two EDFA boosters, enabling point-to-point, linear add and drop, and ring topologies in both transponder and regenerator modes. In addition it provides performance monitors as well as facility protection and power supply redundancy. The PL-1000 is ideal for connecting multiple 10-Gigabit Ethernet interfaces over distances of up to 120 km, the company concludes.
