1-Port 10-Gigabit Ethernet Base Module (WS-X6502-10GE)
The 1-port 10-Gigabit Ethernet switching module (WS-X6502-10GE) consists of 
a 10-Gigabit Ethernet Base Module (WS-X6502-10GE) and an Optical Interface 
Module (OIM). (See Figure 1-30.) The following OIMs are currently available:
• WS-G6483 10GBASE-ER Serial 1550-nm Extended Reach OIM
• WS-G6488 10GBASE-LR Serial 1310-nm Long Haul OIM 
The WS-G6483 OIM provides one serial 1550-nm 10-Gigabit Ethernet port 
through an SC connector. The WS-G6488 OIM provides one serial 1310-nm 
10-Gigabit Ethernet port through an SC connector. The switching module is 
upgradable to support distributed forwarding with an optional Distributed 
Forwarding Card (WS-F6K-DFC). Refer to Table 2-8 and Table 2-9 for OIM 
optical specifications.
The QoS port architecture (Rx/Tx) for this module is 1p1q8t/1p2q1t.

The front panel LEDs are described in Table 1-6 on page 1-47.
16-Port Gigabit Ethernet Switching Module (WS-X6516-GBIC)
The 16-port Gigabit Ethernet switching module (WS-X6516-GBIC) provides 
16 switched, full-duplex Gigabit Ethernet ports that you can configure with any 
combination of 1000BASE-SX, LX/LH, and ZX GBICs, copper GBICs, or 
CWDM GBICs. (See Figure 1-31.)
Note CWDM GBICs are used with the CWDM Passive Optical System. For more 
information on the CWDM Passive Optical System, refer to the Installation Note 
for the CWDM Passive Optical System.
