Ultra-wideband Optical DWDM Digital Transport Network

Today’s fiber optic communication networks use dense wavelength division multiplexing (DWDM) to transmit multiple optical signals of different wavelengths over a single fiber, significantly increasing total data throughput beyond the limits of individual transceivers. These wavelengths follow ITU standards for precise channel spacing, enabling interoperability and scalability. In operation, a WDM multiplexer combines multiple laser transmitters into one fiber, while a demultiplexer at the receiving end separates them back into individual channels for detection. Bidirectional transmission is supported, and an optical supervisory channel (OSC), typically operating outside the EDFA band (e.g., 1510 nm or 1620 nm), enables remote monitoring, control, and software upgrades across the network.

Building on this technology, Agiltron’s Ultra-wideband Optical DWDM Digital Transport Network is a highly integrated, carrier-grade platform designed for high-capacity, long-haul applications. It supports single-channel data rates from 100 Mbps up to 400 Gbps, scalable to 800 Gbps, and delivers ultra-terabit capacity across up to 96 DWDM channels in unidirectional or bidirectional configurations. The system enables efficient large-granularity transport with support for 10G, 100G, 200G, and 400G hybrid services, while achieving transmission distances of up to 2,000 km without electrical regeneration. Its modular chassis, available in 1U, 2U, 3U, and 5U formats with up to 20 service slots, provides flexible deployment and high-density integration, including advanced MUX and ODUK processing. Designed for maximum reliability, it features full 1+1 redundancy across client, wavelength, and line interfaces as well as power supplies. Managed by the AG600 network management system, it offers unified, end-to-end control with comprehensive fault, performance, configuration, and security management, delivering a scalable, transparent, and robust solution for modern optical transport networks.
