ST-40G-QSFP-SR4-I
Sate Optics ST-40G-QSFP-SR4-I is a 40Gbps QSFP+ SR4 industrial temperature compatible optical transceiver designed for reliable short-distance Ethernet connectivity in harsh operating environments.
This 40G QSFP+ SR4-I optical module uses four-channel 850nm VCSEL technology to provide 40Gbps transmission over parallel multimode fiber (MMF). It supports up to 100m transmission over OM3 fiber and 150m over OM4 fiber through an MTP/MPO connector.
With an extended operating temperature range from -40°C to 85°C, the ST-40G-QSFP-SR4-I is suitable for industrial networking, outdoor communication systems, and enterprise infrastructure requiring enhanced environmental durability.
