Brand: Cisco · SKU: SFP-50G-SR-S · MPN: SFP-50G-SR-S · Category: Networking
The Cisco SFP-50G-SR-S is a high-performance SFP56 transceiver module designed for 50 Gigabit Ethernet (50GBASE-SR) and 25 Gigabit Ethernet applications. Utilizing 50G PAM4 (Pulse Amplitude Modulation 4-level) technology, this module provides a cost-effective solution for high-bandwidth data center interconnects. It operates over multi-mode fiber (MMF) at a nominal wavelength of 850nm, supporting link lengths of up to 70m on OM3 MMF and 100m on OM4/OM5 MMF. The module is hot-pluggable, allowing for easy installation and maintenance without powering down the network equipment. It features a duplex LC connector and supports Digital Optical Monitoring (DOM) for real-time diagnostic access to operating parameters such as temperature, supply voltage, and optical power levels. Built to comply with the IEEE 802.3cd and SFP56 Multi-Source Agreement (MSA) standards, it ensures seamless integration and interoperability with a wide range of networking hardware.
