SFP-50G-LR-S
Cisco 25/50GBASE-LR SFP56 Module for SMF
The Cisco SFP-50G-LR-S SFP56 transceiver provides long-reach 50GBASE-LR and 25GBASE-LR connectivity up to 15km over single-mode fiber.
SFP-50G-LR-S Overview
The Cisco SFP-50G-LR-S is a 50GBASE pluggable optics module designed for long-reach 25Gbps or 50Gbps connectivity over single-mode fiber. This SFP56 transceiver supports links up to 15km using 1310nm light source, providing an economical solution for 50G connectivity between buildings and across campus networks.
With support for G.652 standard single-mode fiber, the LR-S can utilize existing fiber cabling for smooth migration from 10G or 25G to 50G speeds. The module is compatible with Cisco Nexus switches and routers using PAM-4 modulation for 50G optical transmission.
The SFP-50G-LR-S enables long-reach deployments not typically feasible with multimode modules. It brings trouble-free 50GBASE-LR signal integrity for data center interconnects and high performance networks.
