Extending the network beyond the limits
Westermo has a solution that makes it possible to ignore the limits of communication over conventional cables. Conventional UTP cables allow Ethernet to be transmitted typically up to 100 meters. Wolwerine Ethernet extenders allow you to go much further beyond these boundaries using many different types of cables already installed.
The Wolwerine product line uses twisted pairs, for example, to connect two or more Ethernet networks at high speed. Instead of laying expensive fiber optic or installing radio links, SHDSL technology offers a cost-effective solution over existing cables. With transmission speeds of up to 15.3 Mbit/s and communication distances of up to 15 km, it can be an excellent alternative to fiber optics. These modems are capable of transmitting transparent Ethernet and other protocols on top of it over long distances.
These devices are equipped with the WeOS operating system and can take advantage of all the features that this system offers such as static routing, IPSec VPN, DMZ and a powerful firewall to protect sensitive data.
Full compatibility and interoperability with other Westermo products is a great advantage.Wiring examples:
Point-to-point
With one twisted pair, up to 15.3 Mbit/s transmission speed can be achieved, but with two and the bonding function, the speed doubles up to 30.4 Mbit/s, which is sufficient for most industrial systems.
Chain Topology
The back-to-back connection was very popular for modems with frequency modulation or for devices with RS-485. The use of these cables can give communication a whole new dimension.
Circular Topology
More and more devices are equipped with Ethernet ports, and more and more devices are managing critical operations where a single mistake can have fatal consequences. The circular topology ensures redundancy and in the event of a communication failure, the connection is immediately restored by the other side. With SHDSL modems, many Ethernet or serial devices can be connected to each other over an existing pair and transmit data between them at high speed over long distances. In this circular topology, the unique features of the FRNT topology can be exploited. These products can be combined with all other WeOS operating system products.
