AT-CV Media Converter Line Cards
The AT-CV Line Cards are two-port media converters. They have a
twisted pair port that connects to a local Ethernet network and a fiber optic
port that connects to the remote network over either single-mode or multi-
mode fiber optic cable. Most of these cards have fiber optic ports that have
fixed operating distances. However, the AT-CV1KSS Line Card has two
slots for SFP modules for transferring traffic between a twisted pair port
and a fiber optic port, or two fiber optic ports, depending on the modules.
All of the fiber optic ports on these line cards are standard Ethernet ports.
They can be connected to other Fast Ethernet or Gigabit Ethernet devices
that have compatible fiber optic ports, including other media converters.
The operating specifications of the fiber optic ports can be found in the
Installation Guides that ship with the line cards.
Although these line cards do not have management software and are
primarily intended as unmanaged devices, you can use the AT-CV5M02
Management Card to change their operating modes or to view card and
port status. Their port settings are not adjustable. They have DIP switches
for setting the cards’ operating modes and the MDI/MDI-X setting for the
twisted pair ports.
This series supports the following operating modes. For background
information, refer to “Operating Modes” on page 42.
