ST-10/25G-SFP28-CSR-S
Sate Optics ST-25G-SFP28-CSR-S is a dual-rate 10G/25G SFP28 compatible optical transceiver designed for flexible Ethernet network upgrades and data center connectivity.
The module supports both 10Gbps and 25Gbps Ethernet data rates, providing backward compatibility between existing 10G infrastructures and next-generation 25G networks. Using an 850nm VCSEL transmitter and multimode fiber (MMF), it delivers reliable short-distance optical connectivity for switches, routers, and server connections.
The ST-25G-SFP28-CSR-S compatible transceiver is suitable for data centers and enterprise networks requiring a smooth migration from 10G to 25G Ethernet while maintaining existing optical infrastructure.
