    AI Overview
    Cisco-compatible 25GBASE-LR CWDM SFP28 transceivers enable 25Gbps data rates over single-mode fiber (SMF), utilizing CWDM wavelengths (typically 1270nm-1370nm) to achieve 10km to 30km distances. These hot-pluggable modules, often replacing standard 1310nm LR optics, are ideal for network upgrades, offering 25G connectivity via Duplex LC connectors. 
    Key Features & Specifications 
    • Data Rate: 25.78 Gbps, with many supporting dual-rate 10G/25G operation.
    • Wavelength: Coarse Wavelength Division Multiplexing (CWDM) wavelengths allow multiple 25G channels on one fiber, often utilizing 1270nm through 1370nm, or standard 1310nm for non-CWDM specific LR.
    • Distance: 10km to 30km over OS2 Single-Mode Fiber (SMF).
    • Connector: Duplex LC/UPC.
    • Compatibility: Designed for Cisco SFP28 ports (switches/routers) and MSA compliant.
    • Diagnostics: Digital Optical Monitoring (DOM/DDM) support for real-time monitoring. 
    Common Models & Variants 
    • CWDM-SFP25G-10km (various wavelengths): Specialized CWDM modules for wavelength multiplexing.
    • SFP-25G-LR-S: Standard 25GBASE-LR 1310nm SMF (10km) transceiver.
    • SFP-10/25G-LR-S: Dual-rate 10G/25GBASE-LR transceiver. 
    Installation Considerations 
    • FEC Requirement: Requires RS-FEC (Reed-Solomon Forward Error Correction) on the host switch ports for optimal 25G performance.
    • Wavelength Selection: Ensure CWDM wavelengths match on both ends of the fiber link.
    • Connector Type: Uses LC connectors, typically on G.652 SMF. 
    These transceivers are available from various manufacturers to work with Cisco infrastructure, such as FS.com CWDM-SFP25G-1490-10 or 10Gtek SFP-25G-LR-S.
