Industrial-grade QSFP+ is a 40 Gbps optical transceiver module designed for reliable operation in harsh environments, featuring an extended operating temperature range of -40°C to +85°C. It is commonly used in applications such as industrial networking and outdoor communications where standard commercial modules are unsuitable. Its key distinction from the newer Industrial QSFP28 lies primarily in the data rate, with QSFP+ supporting 40 Gbps compared to the 100 Gbps of QSFP28, while both share similar ruggedized construction for extreme conditions.
C-light provides QSFP+ (40G, 200m MMF & 2~60km SMF, industrial) for rugged network application.
