About This Part
The Huawei 020RXB, also identified as SSN1SLT103-B3, is a critical optical line interface board within Huawei's renowned OptiX series of Multi-Service Transport Platforms (MSTP). This module is engineered to provide Synchronous Transport Module level 1 (STM-1) connectivity, operating at a standard data rate of 155.52 Mbps. As a core component for SDH (Synchronous Digital Hierarchy) networks, the Part Number 020RXB facilitates the transmission and reception of optical signals, ensuring robust and reliable data transport over fiber optic infrastructure. It typically supports various optical interfaces, conforming to ITU-T G.957 standards for short-haul, long-haul, or ultra-long-haul applications, depending on the specific transceiver type (e.g., S-1.1, L-1.1, L-1.2). Its primary function is to terminate STM-1 optical links, converting optical signals to electrical signals for processing within the MSTP system, and vice-versa, enabling the aggregation and distribution of TDM (Time Division Multiplexing) services. This board integrates seamlessly into the chassis of compatible Huawei OptiX equipment, contributing to the platform's overall capacity and service flexibility. The Huawei 020RXB is widely deployed in telecommunications networks globally, serving as a foundational element in metropolitan, regional, and access networks. It is primarily installed in Huawei OptiX 1500, OptiX 2500, OptiX 3500, and OptiX 6500 series MSTP systems, which are prevalent among fixed-line and mobile network operators, as well as large enterprises requiring dedicated high-speed links. This board enables service providers to establish reliable point-to-point or ring-based SDH connections for various services, including voice, data, and leased lines. It is particularly crucial for extending the reach of traditional TDM services, supporting mobile backhaul for 2G/3G networks, and providing foundational transport for critical infrastructure. For operators looking to maintain or expand existing SDH infrastructure, the 020RXB offers a proven solution for connecting legacy equipment or adding capacity to established transport layers, ensuring continuity and interoperability within diverse network environments. For B2B clients seeking cost-effective and reliable infrastructure solutions, Revo Distribution Limited offers used and refurbished units of the Huawei 020RXB (SSN1SLT103-B3).
