DESCRIPTION
The Siemens Ethernet transceiver is part of Siemens Small
Form Factor transceiver family. It is fully compliant with the
10BASE-FL / 4M-16M Token Ring standards.
This transceiver supports the innovative Volition connectoriza-
tion concept, which competes with UTP/CAT 5 solutions. It is
compatible with RJ-45 style backpanels for fiber-to-the-desktop
applications while providing the advantages of fiber optic tech-
nology. The receptacle accepts the new VF-45 connector.
Ethernet 10BASE-FL is based on the proven effectiveness of
millions of installed Ethernet systems.
This transceiver is completely interoperable with existing SW
solutions for Ethernet and Token Ring.
