Planning the Installation

Be sure to observe the following guidelines when planning the installation
of your media converter.
For AT-DMC1000 media converters, the end node connected to

the fiber connector on the media converter must operate at 1000
Mbps. For AT-DMC100 media converters, the end node connected
to the fiber connector on the 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 media converter copper port will only link up at the same

speed as its fiber port. However, it will only link 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).
Cable specifications for the twisted-pair port are: Standard TIA/EIA

568-A-compliant Category 5 or TIA/EIA 568-B-compliant
Enhanced Category 5 (Cat 5e) shielded or unshielded cabling with
100 ohm impedance and a frequency of 100 MHz.
For the fiber-optic port specifications, refer to "Fiber-Optic Port
Specifications" on page 58.
