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 SFP module
must operate at 100Mbps or 1Gbps.

The two end-nodes connected to the ports of the media converter
must operate with the same duplex mode, either half- or full-
duplex. The twisted-pair port on the media converter can operate in
either mode with Auto Negotiation enabled.

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).

The maximum operating distance of the AT-MMC1000/SP media
converter is dependent on the specific SFP module.

100Mbps and 1Gbps SFP modules are supported.

For a list of supported transceivers, see “Unpacking the Media
Converter” on page 33.
Note
You must purchase the SFP transceiver separately.
