Big news from Yingda! 🚀

Meet our new SFP-1.25G-BX40-3149 – a powerful 1G single‑mode BiDi fiber transceiver that goes the distance: 40km on just one fiber strand (Simplex LC).

🔹 Wavelength: 1310/1490nm
🔹 Temp: -5°C ~ +70°C with DDM
🔹 Saves 50% of fiber cores thanks to single‑fiber bidirectional tech

⚠️ Important: BiDi modules must be used in pairs – one A‑end (Tx1310/Rx1490) and one B‑end (Tx1490/Rx1310). Two same ends won’t work!

Get long reach, lower cost, and smarter design with Yingda.
