Sate Optics provides 2.5G SFP BiDi Transceivers designed for single fiber bidirectional transmission in telecom, access networks and optical communication systems.
2.5G BiDi SFP modules use WDM technology to transmit and receive optical signals through different wavelengths over one single-mode fiber, helping reduce fiber usage and improve network deployment efficiency.
Our 2.5G SFP BiDi transceivers support common transmission distances including 20km, 40km, 60km and 80km, providing flexible solutions for fiber access networks, metropolitan networks and legacy optical systems.
Sate Optics offers OEM-compatible 2.5G BiDi SFP solutions with various wavelength combinations such as 1310nm/1550nm, 1310nm/1490nm and 1490nm/1550nm for different network requirements.
