Ethernet Simple, Fiber Fast

Ethernet Passive Optical Networks (EPON) combine the simplicity of Ethernet with the speed and throughput of fiber optics. Salira has been a leader in the development of EPON systems since its founding in 2000. Now, we’ve simplified things even further with a comprehensive, standards-based product line based on the IEEE 802.3ah protocols.

The Challenge – The high cost and complexity of point-to-point fiber

Today, fiber optic networks are the most effective way to transport large volumes of data, video, and voice traffic at high speeds over long distances. The challenge, however, is getting the power of fiber into homes and offices while keeping equipment and administration costs under control. For most carriers and enterprises, running “point-to-point” fiber connections from the central office to each customer site—which requires installing electronics at both ends of the fiber and managing hundreds of individual connections—is just too expensive.

The Answer – Simple, affordable EPON

EPON systems developed by Salira provide a simpler, more affordable way of extending fiber to your customers. Using a point-to-multipoint topology, EPONs replace the costly electronic components necessary for individual connections in point-to-point configurations with a much smaller number of Optical Line Terminals (OLTs). EPONs reduce Central Office investment, enable simpler provisioning and eliminate power requirements in the Outside Plant. Salira’s cutting-edge EPON systems can be configured in a variety of ways. For residential applications, they are typically deployed in a point-to-multipoint, tree-and-branch architecture. Protected ring architectures are suitable for many business applications, and bus architectures may be used for campus environments and multiple-tenant units.

Hitachi and Salira – A vibrant future

In April 2005, Salira became a wholly-owned subsidiary of Hitachi Communication Technologies, Ltd. and Hitachi, Ltd. With the backing of Hitachi, Salira Systems, Inc. is poised to play a principal role in the global expansion of the optical access systems business.
