FibroLAN ATARA100 100Mbps Any to Any Redundant link converters

The ATARA100 is an MA managed “Any to Any” 100TX to 100FX Redundant Link Access Device. It has been designed to suit the needs of connecting critical/large users to the network, ensuring fail-free operation by protecting both the fiber path and the user interface. The ATARA100 automatically selects the active port on each F/O and TP sides (with priority to “MAIN” ports) and interconnects them.

It has two TP and two F/O connectors. This way end-to-end path and device redundancy is achieved disregarding the type of the remote device, catering to various network resilience scenarios. Upon failure of a MAIN port, the module switches traffic within less than 10 µsecs to the Backup port and alerts the network manager. When the MAIN link is restored, the traffic automatically switches back to it, providing operational consistency and easy tracing of the active path. The switchback occurs immediately after link restoration or following a tunable delay (via the management system) to avoid network instability during the repair process. Inactive Ports (normally Backup) are continuously monitored for link integrity, providing the network manager with valuable information of his system’s readiness. Using front panel switch (or via management), the Redundant Links mode may be disabled. In such case the module functions exactly like a dual channel converter, with each 2 adjacent ports forming a channel.

As a layer 1.5 media converter, it is independent from frame size. It is forced to Full duplex mode yet performs FDX Advertising to force duplex mode on its link partner. The device is offered in a large variety of optical interfaces, both dual and single fiber strand, allowing the extension of the network up to 150km. Selective Fault Propagation from the F/O port to the TP or vice-versa allows further network resilience (provided that the switch/router to which it is connected is properly set to activate an alternate path). Its RJ-45 ports are Auto-Cross compliant, making installation trouble free.

The Subscriber Link Emulation (SLE)- when link partner is an MA enabled device – allows real time notification of the remote user failure while maintaining the fiber link active. The rate limiting mechanism provides the carrier with a platform to ensure SLAs along with high over-subscription rates. Like other MA enabled devices, the ATARA100 is remotely managed via the MetroStar. The embedded MA chip allows full management, eliminating the need of costly SNMP processors and IP addresses in such. ATARA100M devices have the same characteristics and include also SNMP management
