Planning the Installation

Be sure to observe the following guidelines when planning the installation
of your media converter.
The end node connected to the fiber connector on the

AT-DMC1000 media converter must operate at 1000 Mbps.
The end node connected to the fiber connector on the AT-DMC100

media converter must operate at 100 Mbps.
The two end-nodes connected to the ports of the media converter

must operate in full-duplex mode.
The copper port on the media converter only links up at the same

speed as its fiber port; however, it only links up properly using Auto
Negotiation. As such, do not try to force the copper port to match
the speed.
The devices connected to the two ports on the media converter can

be a network adapter card, repeater, switch, media converter, or
router.
The twisted-pair port has a maximum operating distance of 100

meters (328 feet).
Use a TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e)

shielded or unshielded cabling with 100 ohm impedance and a
frequency of 100 MHz.
Note
For the fiber-optic port specifications, see "Fiber-Optic Port
Specifications" on page 61.
