Line Card Descriptions
AT-CM20x Series
The AT-CM20x 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 either a dual ST or a dual SC 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.
