GENERAL DESCRIPTION
The Radiant Communications
Series DL221/DL221A
transceivers
are used to connect two active ethernet network components
together over a fiber optic cable. Radiants unique technology
allows the same transceiver to be used for connecting 10BaseT or
100BaseT components together. The Radiant Communications
Series DL221/DL221A
transceivers allow for extended fiber trans-
mission distances -- in many cases greater than 100 KM. In addi-
tion, the Series DL221A transceivers allow for bi-directional, full
duplex transmission between ethernet components over a single
optical fiber.
It is convenient to think of the
Series DL221/DL221A
transceivers
as having two sections -- an electrical section, which interfaces to
the ethernet component; and an optical section, which interfaces to
the fiber optic cable.
