The Cudy SM100GSA-20 Single Mode 1.25Gb/s SFP Module delivers reliable, high-speed networking for enterprise, data centre, and telecom environments. Designed with an LC connector and operating at a 1310nm FP laser wavelength, this SFP transceiver ensures stable performance for up to 20km transmission over single-mode fiber (SMF). Fully compliant with the SFP Multi-Source Agreement (MSA), it offers seamless integration with a wide range of networking equipment, making it ideal for high-bandwidth applications such as backbone links, long-distance data transmission, and secure point-to-point connections.
Engineered for precision and durability, the SM100GSA-20 features a PIN photodetector for excellent receive sensitivity and a low jitter optical signal that complies with IEEE 802.3z and ANSI Fibre Channel standards. Its LVPECL-compatible data I/O interface and +3.3V single power supply ensure efficient operation, while low EMI and robust ESD protection provide long-term reliability in demanding environments. The module meets laser safety standard IEC-60825, ensuring safe operation in fiber optic networks.
Equipped with Digital Diagnostic Monitoring (DDM) compliant to SFF-8472, the SM100GSA-20 allows administrators to track real-time parameters such as temperature, voltage, and optical power, improving network maintenance and troubleshooting. Its signal ground isolation to case helps reduce interference, ensuring consistent and uninterrupted data transmission. RoHS compliance makes it an environmentally responsible choice without compromising on performance.
With an operating temperature range of 0°C to +60°C, the Cudy SM100GSA-20 is built for versatility, suitable for both controlled data centre environments and remote networking sites. Its compact hot-pluggable design enables quick installation and replacement without service downtime, ensuring maximum network uptime. Whether upgrading existing infrastructure or expanding network reach, this SFP module offers the stability, efficiency, and range needed for modern high-performance fiber networks.
