Brief Introduction
This Vchung DWDM-SFP25G-xx.xx SFP28 transceiver features a high-performance cooled DWDM EML transmitter and high sensitivity APD receiver. This 25G SFP28 module operates on a nominal wavelength of 100GHz ITU Grid, C Band DWDM wavelength. The DWDM transceiver allows 5G network operators to deliver higher bandwidth without deploying new fibers and save more by efficiently utilize existing fiber plants. The DWDM SFP28 transceiver is suitable for 5G wireless fronthaul network applications.
