Huawei OptiX Alps-WDM Solution for Metro Networks

0414

The large-scale deployment of 5G and gigabit optical networks accelerates fixed-mobile convergence (FMC) and drives the continuous increase in network traffic and connections, presenting operators with new service opportunities. Meanwhile, traffic is unevenly distributed at the core, aggregation, and edge layers of metro networks, leading to uneven traffic distribution. A network architecture that matches the traffic trend is required to achieve optimal TCO and ensure network connection quality.

Huawei's latest OptiX Alps-WDM solution extends all-optical switching from the core layer to the access layer. By building a dynamic bandwidth resource pool, this solution achieves 100G to sites and cross-region service wavelength sharing, helping operators reduce network construction costs by more than 30%. It also provides the capacity required for all-service development and evolution over the next decade, facilitating digital transformation for various industries.

Customer Benefits
  • 11 3

    With a flattened network architecture, the solution enables E2E OXC from the core layer to the aggregation layer, and then to the edge layer of a metro network, reducing transmission latency by 60%. It supports smooth evolution of network rates to 400 Gbit/s or higher for striding to 5.5G/F5.5G, future-proofing the network for 10 years with one-off deployment and continuously reducing per-bit TCO.

    By using a resource pooling architecture at the aggregation layer, the solution enables centralized control and on-demand allocation of wavelengths among multiple rings. This greatly improves bandwidth utilization and ensures no bandwidth resources are wasted. By replacing nine traditional subracks with one, the solution requires 80% less space and power consumption and reduces network construction costs.

    With the fully coherent M-QPSK technology customized for metro networks, the solution achieves 100G to CO, 10-fold increase in site bandwidth, and software capacity expansion that meets full-service development requirements — all while reducing network capital expenditure (CAPEX) by 30%.

    The solution attaches a digital optical label to each wavelength to carry O&M information such as the wavelength, bandwidth, and optical power. It can also adopt NCE-based analysis and processing to enable automatic wavelength planning, remote automatic commissioning free of site visits, and one-click E2E service provisioning.

Core Capabilities

5 2

Simplified

The solution uses industry's first M x N WSS and Nano WSS components to extend all-optical switching OXC from the core layer to the edge layer. This simplifies the network architecture, achieves all-optical one-hop connection, reduces latency by 60%, supports networkwide flexible grooming, and shortens TTM by 70%.

10 2

Long-term evolution

The solution uses the customized 100G M-QPSK modulation format and compact integrated coherent transmitter/receiver (ICTR) for metro N x 10G scenarios. This helps to achieve 100G to CO and 10-fold increase in site bandwidth, meet full-service development requirements, and reduce network CAPEX by 30%.

16

Pooling

The solution uses a fully pooled architecture to enable wavelength sharing among multiple rings and on-demand allocation, reducing operators' fiber leasing and routing costs. By using one subrack to replace nine traditional subracks, the solution requires 80% less space and power consumption and reduces network construction costs.

17

Agile

It attaches a digital optical label to each wavelength to carry path, frequency, bandwidth, and power information, and works with the NCE management and control system to implement automatic network planning and O&M.
