  • Intelligent Photonic Switch
Jul 2004
Lynx Photonic Networks Inc.Request Info
CALABASAS HILLS, Calif., July 6 -- Lynx Photonic Networks, a photonic switch company, has introduced an intelligent all-optical protection switch that protects long haul wavelength services for carriers and service providers. The versatile, rugged new LightLeader (LL) 3710, which provides 1+1 or 1:1 protection for DWDM (dense wavelength division multiplexing) systems at the optical physical level, debuted at the recent Supercomm trade show, where it was demonstrated on a shaker table to prove its robustness and reliability.

The company said, "A pair of plug-and-play LL-3710 protection switches, one at each end, is very cost effective and superior to traditional optical-electric-optical solutions. The LL-3710 supports licensable upgrades, allowing operators to minimize their initial deployment cost and 'pay as they grow' through non-traffic-affecting field upgrades. The switch can be used for link, equipment or tributary protection and configured to work either 1+1 (unidirectional or bidirectional) or 1:1 with extra traffic support to optimize resource utilization. Moreover, it can operate either in master-slave or autonomous mode."

Lynx said the LL-3710 provides fast protection switching for increased link availability; carries traffic during power failure; assures break-before-make connectivity, to avoid misconnections; and is shipped with either AC or optional dual-feed -48 volt DC power supplies.

Like all members of the popular LightLEADER 3000 series, the LL-3710 is based on Lynx's planar lightwave circuit solid-state technology, so it has no moving parts. LightLeader's internal optical chip subsystems have survived extreme reliability tests that include withstanding two billion switch cycles without performance degradation. In addition, LightLeader protection switches are data-rate and format independent. They come with an intuitive graphical user interface, hosted on a PC, and can also be managed by simple network management protocol over Ethernet or command line interface through a Telnet session.
