Figure 1-14 Splitter 10-Gbps ITU Tunable Trunk Card Architecture
The Cisco ONS 15530 supports up to four 10-Gbps ITU tunable trunk cards for a total of 4 channels.
10-Gbps Uplink Cards
The 10-Gbps uplink card sends and receives a 10-Gbps 1310-nm signal to and from a 10-Gbps uplink
card on another Cisco ONS 15530, or to and from a 10-GE transponder module on a
Cisco ONS 15540 ESP or Cisco ONS 15540 ESPx. This card accepts up to four (3.125-Gbps line rate)
electrical signals from ESCON aggregation cards, 8-port FC/GE aggregation cards, or a 4-port FC
aggregation card, and combines them into one 10-Gbps signal (see Figure 1-15).
The 10-Gbps uplink card has four separate redundant interfaces to the backplane. Each interface
connects to the switch fabrics on the active and standby CPU switch modules.
