AT-CM212x/1
Series
The AT-CM212x/1 Series (AT-CM212A/1 and AT-CM212B/1) are 100
Mbps copper-to-fiber media converter line cards. The line card contains
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 simplex SC connector with a
maximum operating distance of 15 kilometers (9.4 miles). The twisted pair
port has an RJ-45 connection and a maximum operating distance of 100
meters (328 feet). Both ports feature half- or full-duplex mode operation.
The line cards are hot-swappable into and out of the chassis.
Each AT-CM212x/1 Series line card features the following:
ˆ One 100Base-FX fiber optic port with a simplex SC connector
Refer to “100Base-FX Fiber Optic Ports” on page 27
ˆ One 10/100Base-TX twisted pair port with an RJ-45 connector
Refer to “10/100Base-TX Twisted Pair Ports” on page 29
ˆ Port and system status LEDs
