Table 1-20 lists and describes the 2.5-Gbps ITU Trunk Card LEDs.
10-Gbps ITU Trunk Cards
The 10-Gbps ITU trunk card sends and receives the ITU grid wavelength signal to and from an OADM
module. This card accepts up to four 2.5-Gbps (3.125-Gbps line rate) electrical signals from the 10-port
ESCON aggregation cards and 8-port FC/GE aggregation cards, and combines them into one 10-Gbps
signal, which is converted to the ITU grid wavelength, or channel. The 10-Gbps ITU trunk card has four
separate redundant interfaces to the backplane, each connecting to the switch fabrics on the active and
standby CPU switch modules.
The 10-Gbps ITU trunk card has two versions: nonsplitter and splitter. 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 (see
Figure 1-28). The splitter version of the 10-Gbps ITU trunk card has two pairs of optical connectors on
the front panel, which connect to the east and west OADM modules, and is designed for splitter protected
applications (see Figure 1-29).
The Cisco ONS 15530 supports up to four 10-Gbps ITU trunk cards for a total of four channels.
