LPU–NSQ1XP20
Introduction to 10 GE interfaces
NSQ1XP20 provides two XFP interfaces (10GBASE–R), which operate in the LAN PHY mode rather
than the WAN PHY mode. An XFP interface operating in the LAN PHY mode supports a maximum
data-rate of 10.3125 Gbps. The LED for an XFP interface is on the right of the interface, indicating the
status of the interface. For the description of the XFP interface LEDs, refer to Table 1-9.

Cable connecting 10 GE interfaces
You can use a single-mode or multimode fiber to connect an XFP interface and select proper fibers for
the installed XFP optical modules (XFP transceivers for short). Since the optical interfaces on these
XFP transceivers use LC optical connectors, you must use fibers with LC optical connectors. All XFP
transceivers are hot-swappable. Figure 1-13 shows an XFP transceiver. For a fiber with LC connectors,
see Figure 1-11.
