Cudy Fiber SFP Module 1.25Gb/s SM 20km Dual-LC SM100GSA-20

Upgrade and extend your network infrastructure with the Cudy SM100GSA-20 (CD-SFP-SM) 1.25Gb/s Single Mode SFP Optical Transceiver Module. Built for demanding enterprise, telecom, and campus backbones, this duplex optical module provides stable, high-speed Gigabit data transmission over distances of up to 20 kilometers on standard 9/125µm single-mode fiber (SMF).

High-Speed Long-Distance Optical Connectivity

Designed with a precision 1310nm FP laser transmitter and a sensitive PIN photodetector, the SM100GSA-20 delivers clean, jitter-free signal transmission across long fiber links. It is the perfect solution for switch-to-switch uplinks, router interconnects, and fiber-to-copper media converter extensions where copper cabling cannot reach.

Enterprise Reliability and Diagnostic Monitoring

Compliant with SFF-8472 Digital Diagnostic Monitoring (DDM/DOM) standards, this optical module allows network administrators to monitor real-time operating parameters such as optical output power, optical input power, temperature, and transceiver supply voltage. Enhanced with integrated electro-static discharge (ESD) protection and low electromagnetic interference (EMI) engineering, it guarantees maximum operational uptime.
