Overview
The AT-CM20x Series (AT-CM201, AT-CM202, and AT-CM202/x Series) line
cards are 10/100 Mbps copper-to-fiber media converter line cards. These line
cards can be installed in any of the Converteon™ Media Converter chassis,
including the AT-CV5000, AT-CV1000, and AT-CV1200. Each line card
features one fiber optic port and one copper twisted pair port. The fiber optic
port operates at a fixed operating speed of 100 megabits per second (Mbps)
and the twisted pair port operates at 10 or 100 Mbps speed. The fiber optic
port is IEEE 802.3ah-compliant and has a either a simplex SC, dual SC, or ST
connector with a maximum operating distance from 2 kilometers (1.24 miles)
to 40 kilometers (24.8 miles), depending on the model. The twisted pair port
has an RJ-45 connector and a maximum operating distance of 100 meters
(328 feet). Both ports feature half- or full-duplex mode operation. The line
card is hot-swappable into and out of the chassis.
