About This Part
The Huawei SL91SL1DA05 is a critical interface board designed for Synchronous Digital Hierarchy (SDH) transmission systems. It provides two STM-1 (Synchronous Transport Module, Level 1) electrical interfaces, each capable of supporting data rates up to 155.52 Mbit/s. These boards are typically deployed in telecom central offices, data centers, or enterprise networks to aggregate and transport various types of traffic, including voice, data, and video, over existing electrical infrastructure. Its primary function is to facilitate reliable, high-speed connectivity between network elements within a metropolitan or regional area network, often serving as an aggregation point for lower-speed tributaries or for interconnecting equipment racks. As an electrical interface board, the SL91SL1DA05 is engineered for robust performance and compatibility within Huawei's extensive range of SDH equipment. Its electrical nature makes it suitable for shorter-distance connections, offering a cost-effective solution for intra-site or inter-rack connectivity where optical fiber deployment might be impractical or unnecessary. Revo Distribution Limited specializes in providing high-quality used and refurbished telecom and data centre equipment. We carry parts like the Huawei SL91SL1DA05 to support the ongoing operational needs of network operators and service providers who maintain legacy SDH infrastructure. This ensures continued service delivery and extends the lifespan of existing network investments, offering a sustainable and economical alternative to new equipment procurement.
