About This Part
The Huawei 03031JYK, identifiable by its internal code CR5D00C2CF70, is a high-performance 2-Port Channelized STM-1c Packet Over SONET/SDH (POS) Flexible Card. This modular interface card is engineered to integrate seamlessly into Huawei's advanced networking platforms, delivering robust optical connectivity solutions. Designed for efficient data transport, it provides two independent STM-1c interfaces, each supporting a data rate of 155.52 Mbps. The 'channelized' capability allows for the aggregation and de-aggregation of multiple lower-speed data streams within the STM-1c payload, optimizing bandwidth utilization. Each port accommodates Small Form-Factor Pluggable (SFP) transceivers, offering versatility in selecting appropriate optical wavelengths and transmission distances to meet diverse network requirements. This Huawei card is critical for environments demanding reliable, high-speed optical links for packet-based services over traditional SDH/SONET infrastructure. The Huawei 03031JYK card is typically deployed within the chassis of Huawei's carrier-grade routing and optical transport platforms, serving as a vital component for extending network reach and capacity. It is instrumental in scenarios where telecommunication operators, internet service providers (ISPs), and large enterprise networks need to transport packet-based traffic efficiently over Synchronous Digital Hierarchy (SDH) or Synchronous Optical Networking (SONET) infrastructures. This card effectively addresses the challenge of integrating modern IP/Ethernet services with established optical transport layers, facilitating seamless data flow. Common use cases include providing high-speed backhaul for mobile base stations, interconnecting data centers, and delivering dedicated leased line services for business customers. By offering flexible, channelized STM-1c POS connectivity, it enables network providers to optimize their existing infrastructure investments, upgrade legacy systems with enhanced packet capabilities, and support a diverse range of applications requiring robust and scalable optical transport.
