Cisco 15454-OC48LR1550 Optical Interface Module

The Cisco 15454-OC48LR1550 Optical Interface Module provides long-reach OC-48 SONET connectivity over single-mode fiber for the Cisco ONS 15454 Optical Transport System, enabling high-capacity links between core and edge nodes in carrier-grade infrastructure and supporting reliable backbone transmission across metropolitan and regional networks. This slot-based module is designed for Cisco ONS 15454 chassis and supports Optical Standard OC-48 / SDH STM-16 with data rates up to 2.488 Gbps, using a 1550 nm wavelength on SMF and an LC connector for consistent, high-quality transmission. Key specifications include connection type: LC, fiber: single-mode (SMF), installation type: slot-based, and application category: optical transport networking interface, all contributing to scalable, high-speed optical paths within service provider and enterprise networks. Platform compatibility and the 15454 series integration make this module suitable for expanding transport capacity, replacing failed interfaces, and maintaining SONET backbone connectivity in carrier-grade networks. Common deployments span service-provider SONET networks, metro fiber rings, optical transport systems, enterprise backbone networks, and ISP network aggregation points where long-distance fiber connectivity is required for reliable high-speed data transmission.
