4-Port 1-Gbps/2-Gbps FC Aggregation Cards
The Cisco ONS 15530 supports a line card specifically for 1-Gbps and 2-Gbps FC (Fibre Channel),
FICON (Fibre Connection), and ISC (InterSystem Channel) links traffic. The 4-port 1-Gbps/2-Gbps FC
aggregation card has the following features:
• Accepts up to four single-mode or multimode SFP (small form-factor pluggable) optics for client
traffic. Each SFP optic supports 1-Gbps or 2 Gbps FC, FICON, or ISC traffic, depending on how the
interface is configured in the CLI.
• Does not restriction how you can populated the card with SFPs. For example, you can mix a
single-mode SFP optics with a multimode SFP optics in the same aggregated signal.
• Converts up to four client signals from optical form to electrical and transmits them over up to four
2.5-Gbps electric signals. These signals pass through the backplane and the switch fabric on the
active CPU switch module to a 2.5-Gbps ITU trunk card, a 10-Gbps ITU trunk card, or a 10-Gbps
uplink card. The cross connections between the two cards through the backplane and switch fabrics
are configured using the CLI.
• Allows different traffic types on the same card and on the same aggregated signal.
• Allows two 1-Gbps protocol client signals to be aggregated on one 2.5-Gbps signal sent over the
switch fabric. Only one 2-Gbps protocol client signal can be sent over a 2.5-Gbps signal over the
switch fabric.
• Has redundant connections over the backplane to the switch fabrics on the active and standby CPU
switch modules.
• Is compatible with the 8-port FC/GE aggregation card signals. Any 1-Gbps FC, FICON, or ISC
signal can be transmitted between a 4-port 1-Gbps/2-Gbps FC aggregation card and an 8-port FC/GE
aggregation card.
Note The 8-port FC/GE aggregation card does not support 1-Gbps ISC peer mode.
• Provides buffer credit functionality for Fibre Channel.
