Chapter 3: AT-MCF2012LC, AT-MCF2012LC/1 and AT-MCF2032SP Modules
32 Section I: Features
Overview
The AT-MCF2012LC, AT-MCF2012LC/1, and AT-MCF2032SP Modules
are high-density media converter modules that are used to connect Fast
Ethernet or Gigabit Ethernet networks over large geographical distances.
The modules have twelve channels. Each channel functions as an
independent media converter that transfers network traffic between a
twisted pair port and a fiber optic port or an SFP slot.
The modules feature low latency to minimize the impact on network
performance along with cyclic redundancy check (CRC) detection to
prevent the propagation of incomplete or fragmented packets on your
network.

The standards and features of the modules are listed here:
❒
IEEE 802.3 10Base-T
❒
IEEE 802.3u 100Base-TX
❒
IEEE 802.3u 100Base-TX
❒
IEEE 802.3u 100Base-FX compliant
❒
IEEE 802.3ab 1000Base-T (AT-MCF2032SP Module)
❒
IEEE 802.3u Auto-Negotiation on the twisted pair ports
❒
Hot-swapping so the modules can be installed while a chassis is
powered on.
