Overview

Twisted Pair Port
The AT-MC115XL and AT-MC116XL media converters have one 10Base-T/
100Base-TX twisted pair port. The twisted pair port features a RJ-45
connector. The maximum operating distance for the twisted pair port is 100
meters (328 feet) when operating at either 10 Mbps or 100 Mbps.
Fiber Optic Port
The AT-MC115XL and AT-MC116XL media converters have one 10Base-FL/
100Base-SX port. The fiber optic port features either an SC or ST connector,
depending on the model. The maximum operating distance for the fiber optic
port for both the AT-MC115XL and AT-MC116XL is 2 kilometers (1.2 miles)
when operating at 10 Mbps and 300 meters (984 feet) when operating at 100
Mbps.
Auto-negotiation
Port Speed
The twisted pair port is compliant with the 10Base-T and 100Base-TX
standards and is capable of either 10 Mbps or 100 Mbps operation. Since the
port is IEEE 802.3u auto-negotiation compliant, the media converter sets the
port speed automatically. With auto-negotiation, the speed of the port is set
automatically by the media converter after it determines the speed of the end-
node connected to the port. Auto-negotiation is designed to ensure that the
port on the media converter and the end-node are operating at the same speed
and that they are communicating at the highest possible common speed of the
devices.
The fiber optic port is compliant with the 10Base-FL and 100Base-SX
standards and can auto-negotiate the operating speed. The end-node
connected to the fiber optic port on the media converter must also be able to
operate at 10 Mbps, 100 Mbps, or auto-negotiate the operating speed.
Note
The end-nodes connected to the ports on the media converter must be
able to operate at the same speed.
