SFP28 WDM OPTEC 25G SM LC 80 km DFB/APD TX1314 DDM

SFP28 25G BiDi transceivers are advanced optical modules enabling 25 Gb/s transmission over a single optical fiber thanks to WDM (Wavelength Division Multiplexing) technology. The BiDi (Bidirectional) solution allows simultaneous transmission and reception over two different wavelengths, significantly reducing the demand for fiber infrastructure.

Modules in the SFP28 form factor are an evolution of the SFP+ standard and are designed for high port-density environments such as data centers and cloud infrastructure. They share the same mechanical dimensions as SFP+ modules but feature electronic components adapted for 25 Gb/s transmission. This eliminates the need to replace passive infrastructure. Additionally, SFP28 transceivers are backward compatible with SFP+ ports – they can be used in SFP+ slots, although the speed will be reduced accordingly. Conversely, switches supporting 25 Gb/s technology and equipped with SFP28/SFP+ ports allow the use of SFP+ modules in SFP28 ports by adjusting the port speed in the device settings. Compatibility also applies to PCC (Passive Copper Cable) and ACC (Active Copper Cable).

Key features:

• Data rate: 25 Gb/s
• BiDi technology (single-fiber transmission)
• Compliance with 25 Gigabit Ethernet standard
• DDM/DOM support – digital operating parameter monitoring
• Hot-pluggable (replaceable during device operation).

Available reach variants:

• Short-range modules - SR
• Long-range modules - LR/ER.
