Table 1-13 describes the LEDs on the 8-port FC/GE aggregation card.
2.5-Gbps ITU Trunk Cards
The 2.5-Gbps ITU trunk card sends and receives the ITU grid wavelength signal
to and from an OADM module. This card accepts a 2.5-Gbps (3.125-Gbps line
rate) electrical signal from either a 10-port ESCON aggregation card or an 8-port
FC/GE aggregation card, which is converted to the ITU grid wavelength, or
channel. The 2.5-Gbps ITU trunk card has redundant interfaces to the backplane,
connecting to the switch fabrics on the active and standby CPU switch modules.
The ITU laser is tunable to one of two channel frequencies. There are 16 different
2.5-Gbps ITU trunk cards (for channels 1–2, 3–4,..., 31–32) to support the
32 channels.
The 2.5-Gbps ITU trunk card has two versions: nonsplitter (shown in Figure 1-24)
and splitter (shown in Figure 1-23). The nonsplitter version has only one pair of
optical connectors on the front panel, which connects to either the east or the west
OADM module, and can be used for unprotected, line card protected, or switch
fabric protected applications. The card supports 32 channels as shown in
Table A-2 on page A-3.
