Cisco 15454-MR-L1-54.1 Multi-Rate Transponder Module

The Cisco 15454-MR-L1-54.1 is a Multi-Rate Optical Transponder Module for the Cisco ONS 15454 platform, delivering four DWDM channels and support for data rates from 100 Mbps up to 2.5 Gbps. It fits in a slot within the ONS 15454 chassis and converts client data to optical wavelengths for long-distance fiber transmission, enabling scalable capacity and dependable SONET/SDH backbone operation. The module covers an optical wavelength range of 1554.13 to 1556.55 nm and is designed for carrier backbone networks, metro optical rings, ISP infrastructure, long-haul fiber transport systems, and enterprise optical transport networks requiring reliable multi-rate signaling. Compatible with the Cisco ONS 15454 platform, it serves as a replacement for failed transponders or a means to expand optical transport capacity across backbone links and rings. Its four-channel DWDM interface and slot-based installation provide flexible service aggregation for optical transport networking hardware. Common replacements include Cisco 15454-MR-L1-50.1, Cisco 15454-MR-L1-58.1, and Cisco 15454-MRP-L1-54.1.
