Sate Optics provides 1.25G SFP BiDi Transceivers designed for Gigabit Ethernet transmission over a single strand of optical fiber using bidirectional WDM technology.
1.25G BiDi SFP modules transmit and receive optical signals through different wavelengths on one fiber, helping reduce fiber deployment costs and maximize existing fiber resources.
These single fiber optical transceivers are widely used in enterprise networks, access networks, telecommunications and fiber extension applications where additional fiber installation is difficult or expensive.
Sate Optics offers OEM-compatible 1.25G SFP BiDi solutions with multiple wavelength combinations and transmission distances, including 10km, 20km, 40km and 80km options.
