CYGNUS 894 Ring for Ethernet and RS 232 devices
Ideal for extending ports of a central Ethernet Switch to multiple remote locations in a premises using an Optical Fiber Ring.
Option is available for also accommodating async RS232 devices on the same Ring, by providing raw point-to-point connections between RS232 ports at the central site and the remote site.
A Ring comprises of a CYGNUS 894C Central Node, and up to 8 CYGNUS 894R Remote Nodes. Each Node has 2 Fiber ports using which it connects to its previous and subsequent neighbouring nodes. The Ring is closed by connectinga fiber port of the last Remote Node back to the Central Node.
The Central Node can have a mix of Ethernet and RS232 interfaces. Two typeof Remote Nodes are available – one with Ethernet interfaces, and the other with RS232 interface.
The Ring network offers “ring protection”, i.e., if a fiber segment between 2 adjacent nodes fails, all user devices continue to have connectivity with the central site. Similarly If a Remote Node fails, user devices connected to the working Remote Nodes continue to have connectivity with the central site.
The network avoids the cable clutter at the central sites which is common when point-to-point solutions such as LAN Extenders, Media Converters or Modems are used to extend connectivity from a central site to multiple remote sites. The cable length required to cover a premises is also less than that required in point-to-point solutions.
The Network is flexible as it can be easily reconfigured to add, remove or shift nodes at a later date if required.
Ring status is monitored continuously. Indicators on the Central Node allow easy identification of failed fiber segments or non-working Remote Nodes.
Nodes may be ordered with AC or DC power supply
