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.

Good quality, but hard
Color: Brown
The leather and metal seem to be of very good quality. My son bought this as his office/study chair. He is starting medical school and liked the professional look of this chair. He is 6’ tall and 200lb. There does not seem to be an issue with the chair rolling even with his weight. The chair is very ‘hard’ not that comfortable if you need to sit in it for long periods. Since my son needs to be staying awake to study, this will work for him as he won’t be able to get too comfortable and fall asleep.

Easy assembly and smooth movement
This chair has been a great addition to my home office. The assembly instructions are simple and easy to follow. The height adjusts smoothly, and the chair is very comfortable. I sit at my desk for about 9 hours a day, and this chair makes it easy to stay seated and work for long hours without discomfort. The cushioning and back support are solid. It spins well, and the wheels move smoothly. The build quality feels sturdy and reliable. Overall, a great value and a solid choice for anyone with a desk job. Highly recommend.
