About This Part
The Huawei 03031ESR, identified by its internal designation CR5D00N2NC61, is a high-performance 2-Port 100G OTN/ETH-CFP2 Flexible Card. This module is a critical component within Huawei's advanced optical transport network (OTN) and data center interconnect (DCI) platforms, designed to meet the escalating demands for bandwidth and service flexibility. Operating as a line card, it occupies a single sub-slot within compatible chassis, providing dual 100 Gigabit Ethernet (GbE) or Optical Transport Network (OTN) interfaces. Each port supports a data rate of 100G, leveraging CFP2 pluggable optical transceivers for versatile connectivity options across various distances and fiber types. Its "flexible" nature allows for dynamic configuration to handle diverse traffic types, including native Ethernet and OTN services, ensuring efficient aggregation and transport of high-speed data streams over metropolitan and long-haul networks. This card is engineered for robust performance and reliability in demanding carrier-grade environments. The Huawei 03031ESR is typically deployed in core and aggregation layers of telecommunications networks, internet service provider (ISP) infrastructures, and large-scale data centers. It integrates seamlessly into Huawei's OSN series platforms, such as the OSN 8800 or OSN 9800, providing essential capacity expansion and service delivery capabilities. Telecom operators and data center providers utilize this card to address the growing need for high-speed interconnects between data centers, establish robust backbone links, and support the proliferation of 5G backhaul and cloud services. It effectively solves the challenge of converging multiple service types onto a single, high-capacity optical infrastructure, reducing operational complexity and capital expenditure. This flexible card serves as a vital upgrade path for networks transitioning from 10G or 40G interfaces to 100G, enabling future-proof infrastructure that can scale with increasing data traffic and evolving service requirements.
