The OC-3/STM-1 ATM optical interface board provides 155M transmission channels, and the
OC-12/STM-4 ATM optical interface board provides 622M transmission channels. Both boards use
hot-pluggable SFP optical modules. In actual networking, you must first choose the optical interface
board type based on ATM network rate, and then choose the proper SFP optical module based on
transmission distance.
Specifications
Currently, the NE80 supports two types of OC-3/STM-1 ATM optical interface boards (CR-A4CFF
and CR-A8CFF) and one type of OC-12/STM-4 ATM optical interface board (CR-A2HFF).
