Differences between the CEL36LQFD and CEL36CQFD

Hello,

1. The CEL36LQFD card has 36 interfaces. Starting from interface 0, every four interfaces form a group. The total interface rate of a group cannot exceed 200 Gbit/s. When the Nth port is used as a 100GE port, the (N+2)th port is unavailable and is in the DOWN (Port unavailable) state. As shown in the following figure, when port 0 on the CEL36LQFD board is used for 100G services, port 2 is unavailable. When port 1 is used for 100G services, port 3 is unavailable. The rest can be deduced by analogy.

2. The CEL36CQFD board has 36 interfaces. Each interface can work at 40 Gbit/s or 100 Gbit/s. The actual interface rate depends on the optical module. If a 40GE optical module is used, the interface rate is 40 Gbit/s. If a 100GE optical module is used, the interface rate is 40 Gbit/s, the interface rate is 100 Gbit/s.

3. The CEL24LQFD card has 24 interfaces. The usage of the interfaces is the same as that of the CEL36LQFD card. Starting from interface 0, every four interfaces are grouped into one interface group. The total rate of the interfaces in one interface group cannot exceed 200 Gbit/s. When the Nth port is used as a 100GE port, the (N+2)th port is unavailable and is in the DOWN (Port unavailable) state. As shown in the following figure, when port 0 on the CEL36LQFD board is used for 100G services, port 2 is unavailable. When port 1 is used for 100G services, port 3 is unavailable. The rest can be deduced by analogy.

4. The CEL18CQFD card has 18 ports. Each port can be used as a 40GE or 100GE port. There is no special requirement for the port rate. The actual port rate depends on the optical module. If a 40GE optical module is used, the interface rate is 40 Gbit/s. If a 100GE optical module is used, the interface rate is 100 Gbit/s.

5. The CEL48XSFD board has 48 ports. When the optical ports work in GE mode, they support SFP GE optical modules and 1000BASE-T copper modules (02314171). The copper modules support auto-sensing to 100M/1000M. When working in 10GE mode, optical interfaces support SFP+ 10GE optical modules, 10GE high-speed cables, and AOCs.
