NG-PON2 (also known as TWDM-PON), is a telecommunications network standard for a passive optical network (PON). Its capable of total network throughput of 40 Gbit/s, corresponding to up to 10 Gbit/s symmetric upstream/downstream speeds available at each subscriber.
GEZHI Photonics supplying WM1 and CEx modules that fit the NG-PON2 requirements. The Wavelength Multiplexer (WM1) is a passive device used to support Next Generation PON (NG-PON2). it combines and separates the C and L band DWDM bi-directional transmission.
