The Cisco ONS 15200 series is a DWDM system optimized to cost-efficiently meet the capacity and scalability requirements in metropolitan networks. It offers simplicity and the capability of exploiting limited physical resources such as fibers, conduits, and floor space to their fullest. The Cisco ONS 15200's modular architecture addresses various network applications with different levels of protection capability cost-effectively using the same basic building blocks. The Cisco ONS 15200 is extremely scalable but does not compromise transmission performance.High transmission efficiency allows for more channels, more nodes, and greater distances without amplifiers. With the majority of metropolitan collector rings employing a hub traffic configuration, the ONS 15200 series provides cost-effective provisioning. The ultra-compact single-channel collector node for the ONS 15200 ensures minimal footprint and low power requirements at points of presence. This is complemented by the general-purpose, multiwavelength node for the ONS 15200, designed for use at hub/gateways and meshed traffic applications of the metro core. The modular system architecture of the Cisco ONS 15200 facilitates upgrades, allowing service providers to deploy additional capacity channel-by-channel, anywhere, anytime. Finally, the Cisco ONS 15200 provides advanced channel-by-channel traffic protection options with full Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) compatibility and switching times of less than 1 ms.Cisco offers you Multi-Channel Unit, Mechanics + CIM, covers, and accessory kit.
