ST-25G-SFP28-BD23-10I

25G SFP28 BiDi BD23 Industrial Optical Transceiver — 10km Single-Fiber, -40~85℃

The Sate Optics ST-25G-SFP28-BD23-10I is a 25G SFP28 BiDi industrial optical transceiver rated for -40~85℃ operation, for single-fiber links up to 10km. It transmits at 1270nm and receives at 1330nm over one LC single-mode fiber, and deploys in matched pairs with its BD32 counterpart at the far end — doubling fiber capacity where strands are scarce.

Why This Module

• 10km over one fiber: bidirectional 1270nm TX / 1330nm RX on a single LC strand
• Matched-pair design: pair with the BD32 end to complete the link
• DDM monitoring: real-time optical power, temperature and voltage readings across the full industrial range

• Compatible with your platform — coded for major networking platforms, including Cisco, Juniper, Arista, Huawei, Nokia, H3C and ZTE; 100% tested before shipment.
