ST-25G-SFP28-SR+
Sate Optics ST-25G-SFP28-SR+ is a 25Gbps SFP28 SR+ compatible optical transceiver designed for extended short-distance multimode fiber connectivity in data center and enterprise networks.
The module uses an 850nm VCSEL transmitter and multimode fiber (MMF) to support 25G Ethernet transmission up to 300m over OM4 fiber. Compared with standard SR transceivers, the SR+ version provides extended reach while maintaining low power consumption and high-density connectivity.
The ST-25G-SFP28-SR+ compatible transceiver is suitable for data center switch-to-switch, server-to-switch, and high-performance Ethernet applications requiring longer short-range optical connections.
