Dual Fiber 4 channel TWDM WM1 WDM LGX Module for NG-PON2 OLT
Dual 4 channel TWDM WM1 WDM LGX Module for NG-PON2 OLT, LC/UPC
WM1 module is a passive optics used to support Next Generation PON (NG-PON2) with up to 40 Gigabit capacity via 4 wavelengths (4x10G per port). It combines and separates the 4 downstream (L-Band) and upstream (C-Band) wavelengths over a single fiber.
Channel 1 Central wavelength 1532.68 /1596.34nm
Channel 2 Central wavelength 1533.47 /1597.18nm
Channel 3 Central wavelength 1534.25 /1598.04nm
Channel 4 Central wavelength 1535.04 /1598.89nm
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.
