3Com Router Module Guide Chapter 4 The following figure illustrates the ROUTER 1-PORT OC-3 ATM SML FIC panel. Figure 4-38 ROUTER 1-PORT OC-3 ATM SML FIC panel The following table describes the LEDs on the card panels. Table 4-24 LEDs on the ATM card panels LED Description LINK OFF means no link is present; ON means a link is present. OFF means no data is being transmitted or received on the interface and blinking means ACT data is being transmitted and/or received. 4.10.4 Interface Optical Fiber The ROUTER 1-PORT OC-3 ATM MM FIC uses multi-mode optical fiber and the ROUTER 1-PORT OC-3 ATM SM FIC/ROUTER 1-PORT OC-3 ATM SML FIC uses single-mode optical fiber. As they all use SC-type fiber-optic connectors, the connectors of the optical fibers must also be SC-type connectors. You are available with several cable length options. For more information, refer to the section "Connecting the Interface Optical Fiber". Warning: Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which are connected with lasers. To protect your eyes against radiation harm, never stare into an open fiber-optic port. 4-40

Interface Optical Fiber
The ROUTER 1-PORT OC-3 ATM MM FIC uses multi-mode optical fiber and the
ROUTER 1-PORT OC-3 ATM SM FIC/ROUTER 1-PORT OC-3 ATM SML FIC uses
single-mode optical fiber. As they all use SC-type fiber-optic connectors, the
connectors of the optical fibers must also be SC-type connectors. You are available
with several cable length options. For more information, refer to the section
“Connecting the Interface Optical Fiber”.
Warning:
Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which are connected
with lasers. To protect your eyes against radiation harm, never stare into an open fiber-optic port.
