To ATM network
Connect the ATM SMI3 and
MM3 Ports
The SMI3 (OC-3c/STM-1 single-mode
intermediate reach) and MM3
(OC-3c/STM-1 multimode) ports provide
an interface to ATM networks and transmit
and receive data at rates of up to 155 Mbps
bidirectionally. The SMI3 and MM3 ports
connect to a SONET/SDH single-mode or
multimode optical fiber cable. Use one
duplex SC-type connector or two simplex
SC-type connectors.
Warning
Class 1 laser product.
Warning
Because invisible laser
radiation may be emitted from the
aperature of the port when no fiber
cable is connected, avoid exposure
to laser radiation and do not stare
into open apertures.
