Huawei MCUD1 Overview
The Huawei MCUD1 is a high-performance main control/uplink board for the MA5608T OLT (Optical Line Terminal), offering 10GE uplink capabilities, system control, and service switching for Fiber-to-the-Home (FTTH) networks, featuring 2x 10GE SFP+ & 2x GE SFP ports, 256G switching capacity (or 512G in load sharing), ISSU, time sync (1588v2), and robust management interfaces for stable, scalable broadband delivery.
Product Features
- High-Speed Uplinks: Integrated 2 x 10GE SFP+ and 2 x GE SFP optical ports for fast data transmission.
- System Control & Switching: Provides core management, service switching, and aggregation, functioning as the brain for the MA5608T.
- Performance: Up to 256G switching capacity in active/standby, or 512G in load-sharing mode, supporting large subscriber bases (up to 2048).
- Reliability: Supports active/standby redundancy and ISSU (In-Service Software Upgrade) for non-disruptive updates.
- Time Synchronization: Includes support for Synchronized Ethernet, 3-stratum clock, and 1588v2 for precise timing.
- Interface & Management: Comes with RJ45 ports for Alarm, Console, and BITS/TOD, plus LEDs for status.
Application Scenarios
Small-City FTTH Network Control for European Regional Operators
A regional telecom operator in Central Europe deployed Huawei MA5608T OLTs with MCUD1 units to build an FTTH network covering 40,000 urban and suburban households. Each OLT was configured with 2 MCUD1 boards in 1+1 backup mode: the active board managed 8 service slots (GPBD GPON boards) and aggregated user traffic via 2 GE uplinks to the regional backbone. The standby MCUD1 synchronized data in real time, ensuring zero service interruption during maintenance. Its -40°C~+65°C design adapted to the operator’s unheated rural machine rooms (winter low -20°C), and remote O&M reduced on-site workload by 40%. The solution achieved 99.99% service availability, supporting smooth operation of broadband and IPTV services for users.
