DWDM Optical Transport Modules for Data Center Interconnect Topologies – Official Technical Overview & Hardware Datasheet

EXECUTIVE SUMMARY

This document provides a comprehensive technical overview and hardware datasheet for the DWDM Optical Transport Modules for Data Center Interconnect Topologies. These carrier-grade modules are engineered to address the surging bandwidth demands between hyperscale, colocation, and enterprise data centers. By leveraging dense wavelength division multiplexing (DWDM) technology, the platform enables the cost-effective scaling of fiber capacity, delivering multi-terabit transport over a single fiber pair. The solution is purpose-built for high-capacity, low-latency, and highly resilient Data Center Interconnect (DCI) topologies, ensuring seamless integration into existing optical transport networks. It embodies a pay-as-you-grow architecture, allowing service providers and large enterprises to scale from 100G to 400G+ per wavelength, optimizing both capital and operational expenditures.

ARCHITECTURE & CHASSIS DESIGN

The DWDM Optical Transport Modules are housed in a compact, modular 1RU or 2RU chassis, designed for high-density deployments in space-constrained data center environments. The architecture is centered around a redundant, hot-swappable controller and power supply design, ensuring maximum service availability. The passive optical layer is fully integrated, supporting multiplexing and demultiplexing of up to 96 channels. The system employs a flexible grid technology, supporting both 50GHz and 75GHz channel spacing, which allows for optimal spectrum utilization and future-proof capacity expansion. The backplane is designed to support non-blocking, line-rate forwarding across all slots, eliminating internal bottlenecks and ensuring deterministic performance for latency-sensitive applications.

HARDWARE FEATURES

The hardware platform offers a rich set of features tailored for DCI environments. Key capabilities include:
– High-Density Transport: Supports a mix of 100G, 200G, and 400G line cards in a single chassis.
– Advanced Coherent Optics: Utilizes programmable coherent DSPs to support multiple modulation formats (e.g., QPSK, 16QAM, 64QAM), enabling adaptive capacity and reach based on link conditions.
– Integrated OTN Framing: Provides robust OAM&P (Operations, Administration, Maintenance, and Provisioning) capabilities, including FEC (Forward Error Correction), performance monitoring, and fault isolation.
– Layer 0/Layer 1 Encryption: Optional line-rate AES-256 encryption ensures data integrity and confidentiality across the optical link.
– Redundant Timing: Supports Synchronous Ethernet (SyncE) and IEEE 1588v2 PTP for precise frequency and phase synchronization.
