Function

High-density 25G all-optical interconnection: 36 SFP28 optical ports (25G rate) with a high-density design, which increases the bandwidth by 2.5 times compared to traditional 10G board cards. It is suitable for the "access - aggregation - core" all-optical networking architecture of medium and large parks, and a single board can aggregate the uplink traffic of multiple 10G / 25G access switches

Ultra-high performance and multi-service carrying: 1.8Tbps switching capacity + 1350Mpps packet forwarding rate, supporting line-speed carrying of high-bandwidth services such as office work, 4K monitoring, video conferencing, VR/AR, etc. Compatible with IPv4/IPv6 dual-stack and MPLS VPN, meeting the requirements of cross-regional interconnection and multi-service isolation

High reliability redundancy and fast convergence: Supports hot plugging and board card redundancy, combined with FRR fast reraining and ECMP load sharing, to avoid service interruption caused by single point of failure; BFD link detection + MSTP spanning tree protocol enables millisecond-level response to network faults and rapid convergence

Flexible networking and expansion compatibility: Backward compatible with 10G rate optical modules, it can smoothly upgrade the existing 10G network to 25G. Supports rich routing protocols and EVPN technology, and is compatible with complex topologies such as the core layer of large parks and multi-branch interconnection

Refined QoS and security control: Through priority mapping and traffic shaping, ensure the bandwidth priority of critical services such as voice, medical care, and government affairs. Multi-layer ACL, encrypted tunnels and other functions resist network attacks and ensure the security of core layer data transmission

Unified operation and maintenance and intelligent monitoring: By integrating with Huawei's unified management platform, it is possible to remotely monitor the status of optical ports, module power, and link traffic. It supports fault classification alarm and remote diagnosis, reducing the difficulty of on-site operation and maintenance of core layer equipment and improving management efficiency

Application scenarios

Core layer of medium and large-sized parks: Core layer switches for large enterprise headquarters, industrial parks, and university campus networks. 36 25G optical ports aggregate the uplink traffic of aggregation switches in each area. Through ECMP load balancing, multi-link redundancy is achieved, supporting the high-bandwidth access requirements of tens of thousands of terminals

Backbone network of large commercial complexes: The backbone interconnection of urban commercial complexes and office building clusters, achieving long-distance interconnection of aggregation switches in each building through 25G optical modules (for example, LR optical modules support 10km), carrying multiple services such as merchant office, 4K monitoring, and public WiFi, ensuring sufficient bandwidth

The core of the university/vocational education park network: The campus network core covering multiple teaching buildings, research buildings, and dormitory areas, with 25G bandwidth supporting high-bandwidth services such as teaching and research, video on demand, remote teaching, and VR training, and IPv6 dual-stack adaptation to the upgrade requirements of the education network

Data center access layer: Access layer switches for small and medium-sized data centers, with 36 25G optical ports directly connected to servers, meet the high concurrency and high bandwidth data transmission requirements of data centers, and enhance reliability in combination with main control redundancy

Core networks in the medical and financial industries: Core switches for large hospital medical parks and regional bank data centers, carrying key services such as medical image transmission, remote consultation, and financial transaction data. 25G high bandwidth and low latency ensure smooth business operations, and the redundant design meets the industry's "zero interruption" requirement

25G upgrade and transformation of campus network: For the original 10G campus network upgrade scenario, replace the traditional 10G service board card with CE-L36LQ-EG to upgrade the access/aggregation layer bandwidth to 25G, be compatible with the existing switch chassis and optical modules, reduce the upgrade cost, and meet the high bandwidth requirements brought about by digital transformation
