About This Part
The Huawei 03031DKB, identified internally as CR2D00C1CF11, is a high-performance 1-Port Channelized STM-1c Packet Over SONET (POS) Physical Interface Card designed for integration into carrier-grade networking platforms. This module provides robust optical connectivity at a Synchronous Transfer Mode level 1, specifically STM-1c, delivering a data rate of 155.52 Mbps. Its channelized capability is a critical feature, allowing the STM-1 bandwidth to be subdivided into multiple lower-speed channels, such as E1/T1 or E3/T3 equivalents, or other specific data streams, enabling flexible service provisioning and efficient bandwidth utilization. The card utilizes a Small Form-Factor Pluggable (SFP) interface, supporting various optical transceivers for diverse reach requirements over single-mode or multi-mode fiber. This design ensures compatibility with existing optical infrastructure while providing a scalable solution for high-density WAN aggregation and transport. The Part Number 03031DKB is typically deployed within Huawei's enterprise and carrier-grade routing and switching platforms, such as the NE series routers or CX series switches, where it serves as a crucial component for wide area network (WAN) connectivity. It is extensively utilized by telecommunication operators, internet service providers (ISPs), and large data center providers to establish reliable and high-capacity links between network nodes, points of presence (PoPs), or remote branch offices. This interface card is instrumental in scenarios requiring the aggregation of diverse traffic types over a single optical link, facilitating the migration from traditional Time Division Multiplexing (TDM) networks to more efficient packet-based architectures while maintaining compatibility with legacy SONET/SDH infrastructure. It effectively addresses the demand for flexible, high-speed optical interfaces for backhaul, inter-POP connectivity, and specialized leased-line services.
