GENUITY ACTIVATES 10 GBPS IP/DWDM WITH JUNIPER / NORTEL'S OPTERA
Genuity activated a 10 Gbps (OC-192c) IP/ DWDM network segment between Atlanta and Washington DC using Juniper Networks M160 routers and Nortel Networks' OPTera LH-4000 ultra-long-reach optics. The route was established with no electrical regeneration of the 10 Gbps optical signal along the 1480-km path. Genuity said it will shift its network architecture away from IP/SONET rings to an optically protected IP/DWDM mesh network.

WORLDCOM TESTS FUJITSU'S 176-CHANNEL TERABIT-CLASS DWDM PLATFORM
WorldCom is testing Fujitsu Network Communications' 176-channel FLASHWAVE OADX DWDM transmission and optical add/drop platform. The system uses 88 channels in each of two bands of the transmission spectrum, the C and L bands, using 50GHz spacing between each channel. Each channel is capable of carrying 10 Gbps of traffic. fnc.fujitsu.com Fujitsu, December 4, 2000

ESSEX CLAIMS 1 GHZ CHANNEL SPACING DWDM SUPPORTING 4,000 CHANNELS
Essex Corporation, an optical and communication engineering company based in Columbia, Maryland, announced a Hyperfine Wave Division Multiplexing system with 1 GHz channel spacing. The system would allow for the transport of 4000 channels and has been demonstrated at 16 GHz with channel spacing of 1 GHz. Essex is developing a series of Hyperfine DWDM modules that can be adapted for any channel spacing, including Gigabit Ethernet at 1.25 GHz and even applications under 1 GHz. essexcorp.com

LYNX PHOTONIC NETWORKS OUTLINES OPTICAL SWITCHING PLANS
Lynx Photonic Networks, a start-up based in Woodlands, California with R&D in Israel, outlined its plans for planar waveguide switches based on silicon substrates with silica-etched waveguides. The devices are targeted at the 8x8 to 64x64 small-to-medium scale optical switches, optical cross-connects (OXC), and optical add-drop multiplexers (OADM). Lynx said its technology would deliver reconfiguration time (>2ms), dynamic power control and weighted multicasting. Prototypes have been delivered to five major telecom equipment companies. Lynx is also working on a 16x16 photonic switch based on the same silica-on-silicon technology. lynxpn.com Lynx Photonic Networks, December 4, 2000 |
