NADDOD OTN Optical Transmission Solution

Mar 2, 2023

The OTN (Optical Transport Network) optical transmission solution based on WDM (Wavelength Division Multiplexing) technology can realize multi-service, large-capacity and fully transparent transmission. NADDOD can flexibly set up various networking architectures according to customers’ needs, such as point-to-point, chain, star, ring, ring-chain, tangent ring, intersecting ring and mesh. They are widely used in SDH/SONET, PDH, Ethernet, SAN, LAN and video transmission fields to meet the maximum backbone core layer, metro core layer, metro aggregation layer, access layer, data center interconnection and other application scenarios with ultra-large capacity and ultra-long-distance transmission requirements.

NADDOD Typical OTN Optical Transmission Solution

The large-scale data center single-fiber bidirectional ring network is composed of NCH 1000-5000 integrated transmission system platform equipped with EDFA optical amplifier board, DCM fixed dispersion compensation board, multiplexing and demultiplexing equipment, network management platform and other optical transmission equipment.

Ring architecture is a resilient and flexible optical transport service designed to provide a more robust transport network and improve operational efficiency. The ring network transmission uses wavelength division multiplexing (WDM) equipment to upload and download multiple services between each node, and constructs a large-scale data center ring network transmission network to realize the interconnection of multiple different types of services between each node in a single-core optical fiber intercommunication. At the same time, the ring network has a protection function to prevent the interruption of the optical cable from affecting the business and improve safety and stability. Any node in the network can realize point-to-point service transmission, and customers can flexibly schedule requirements according to the change of service bandwidth requirements of each node at any time, and support upgrade and expansion.

NADDOD OTN Optical Transmission Solution Advantages

Long-distance Transparent Transmission, Hybrid Networking
The network topology is clear; long-distance transmission, multi-point and multi-channel aggregation, ring-forming and large-bandwidth protection, realize hybrid networking of all sites, and efficient and stable transmission.

Comprehensive Network Management
OEO, EDFA, OLP and other devices are all concentrated in one integrated network management platform, which can realize functions such as device management, monitoring and deployment, software upgrade management, configuration file management, alarm and performance management, and realize comprehensive management from device level to network level. network management.

Modular Design, On-demand Configuration, Flexible Upgrade
The business board adopts a modular design, supports hot swapping, and can be replaced at any time, which is convenient for upgrading and expansion.

Customer Benefits
