ST-40G-QSFP-SR-BD
Sate Optics ST-40G-QSFP-SR-BD is a 40Gbps QSFP+ SR-BD compatible optical transceiver designed for short-distance data center networks and high-speed Ethernet connectivity using existing duplex multimode fiber infrastructure.
This 40G QSFP+ BiDi optical module uses bidirectional wavelength technology with 850nm and 900nm VCSEL channels to transmit 40Gbps data over duplex multimode fiber (MMF). It supports up to 100m over OM3 fiber and 150m over OM4 fiber through a duplex LC connector.
The ST-40G-QSFP-SR-BD compatible transceiver enables 40G network upgrades without replacing existing LC-based fiber cabling, making it suitable for data center interconnects, enterprise networks, and switch-to-switch applications.
