SFP is the plug-in type. You can plug both multi-mode modules and single-mode modules into
the interface board. Different optical modules and optical connectors require different fiber.
The multi-mode interface module connects with the multi-mode fiber; the single-mode
module connects with the single–mode fiber.
The interfaces of FIC low-speed ATM 155M optical modules are equipped with a Square
Connector (SC) optical connector as shown in Figure 5-5. Therefore, Nortel recommends that
you use the fiber with SC/PC optical connectors. In addition, the optical interfaces of
100Base-FX Ethernet optical interface module, Gigabit Ethernet optical interface module, the
HIC high-speed ATM 155M optical interface module and POS optical interface module
should use the Lucent Connector (LC) optical connector as shown in Figure 5-6. Therefore,
Nortel recommends that you use the fiber with LC/PC optical connectors.
5.6.2 Optical connector
The Secure Router 8012 uses two types of optical connectors:
z SC/PC optical connector
z LC/PC optical connector
The following sections describe their outlines, operations, and precautions for plugging in and
unplugging the connectors.
Figure 5-5 shows the outline of the SC/PC optical connectors.
