Item
CE-L36CQJ
Basic function
The card provides data packet processing and traffic management on 36 100GE optical ports or 24 200GE optical ports, which can be used as 36 40GE optical ports or split into 144 25GE or 144 10GE optical ports.
Maximum port density
If all LPUs are these cards:
The CloudEngine 16804 chassis provides a maximum of 144 100GE ports or 96 200GE ports.
The CloudEngine 16808 chassis provides a maximum of 288 100GE ports or 192 200GE ports.
The CloudEngine 16816 chassis provides a maximum of 576 100GE ports or 384 200GE ports.
100GE port
100GE ports on the card support QSFP28 and QSFP+ optical modules. A 100GE port can be used as a 40GE port through auto-sensing, or split into 4 x 25GE or 4 x 10GE ports. The card can provide a maximum port density of 36 x 40GE, 144 x 25GE, or 144 x 10GE. Each 100GE port can be used as a 40GE port through auto-sensing. Every two ports (0-1, 2-3, 4-5, 6-7, 8-9, 10-11, 12-13, 14-15, 16-17, 18-19, 20-21, 22-23, 24-25, 26-27, 28-29, 30-31, 32-33, and 34-35) form a group. The two ports in a group need to be split together, and each port can be split into 4 x 25GE or 4 x 10GE ports.
200GE port
24 ports can work at the rate of 200 Gbit/s and are divided into 12 groups (0 and 1, 2 and 3, 4 and 5, 6 and 7, 12 and 13, 14 and 15, 16 and 17, 18 and 19, 24 and 25, 26 and 27, 28 and 29, and 30 and 31). Such a port works at the rate of 100 Gbit/s by default. You can run the port mode 200GE command to change the port rate to 200 Gbit/s. After the port rate is changed, the port supports QSFP56 optical modules and can work as a 100GE or 40GE port through auto-sensing. The port can be split into two 100GE ports. When the rate is changed for either port in a port group, the other port in the group automatically switches to the same rate. For example, when port 0 is configured to work at the rate of 200 Gbit/s, port 1 is automatically configured to work at the rate of 200 Gbit/s.
Hot swapping
Supported
Restrictions and remarks
Every 12 ports form a group, and three groups (ports 0 to 11, 12 to 23, and 24 to 31) are involved. Each group has a bandwidth limit.
Only the first eight ports in each group can be configured to work at the rate of 200 Gbit/s.
In 3+1 SFU mode, the maximum bandwidth of each group cannot exceed 1.2 Tbit/s (for example, 6 x 200 Gbit/s or 12 x 100 Gbit/s).
In 4+0 SFU mode, the maximum bandwidth of each group cannot exceed 1.6 Tbit/s (for example, 8 x 200 Gbit/s or 8 x 100 Gbit/s + 4 x 200 Gbit/s).
MACsec
Ports 0 to 7, 12 to 19, and 24 to 31 support MACsec. When these ports are configured to work at 40 Gbit/s or are split, MACsec is still supported. Other ports do not support MACsec.

CE-L36CQJ FAQ
Q1: Which Huawei switch models does the CE-L36CQJ support? How compatible is it?
A1: It mainly supports Huawei CE12800 series mid-to-high-end switches (such as CE12804/CE12808), CE8800 series high-end switches (such as CE8868-4C-EI), CE7800 series high-end switches, and some models of the CE9800 series. The interfaces and slots are fully matched, with 100% compatibility; simply plug it in and it's ready to use.
Q2: Does the 36 100G port support backward compatibility with low-speed optical modules? Can existing optical modules be reused?
A2: It supports 100G/40G/25G/10G multi-rate auto-negotiation. Existing 40G, 25G, and 10G optical modules can be used directly without additional purchases, effectively reusing existing assets and reducing upgrade costs.
Q3: How are the power consumption and heat dissipation performance of this interface card? Will it place an additional burden on the switch? A3: It adopts a low-power design, with single-card power consumption controlled at a low level compared to similar high-density 100G interface cards in the industry. It is also compatible with the switch's built-in cooling system, so no additional cooling measures are needed, and it will not put extra pressure on the switch's heat dissipation.
