What is IP over DWDM (IPoDWDM)?

IP over DWDM (IPoDWDM) is a technology used in telecommunications networks to integrate IP routers and network switches in the OTN (Optical Transport Network). A true IPoDWDM solution is implemented only when the IP Routers and Switches support ITU-T G.709. In this way IP devices can monitor the optical path and implement the transport functionality […]

Introduction to O-band WDM

WDM helps the network operators to run several transmission wavelengths on the same pair of optical fiber, it increases the bandwidth capacity among sites. The O-band WDM wavelengths range between 1260nm and 1360nm, compared with C-band featured with lower attenuation, and higher chromatic dispersion, it features a very low chromatic dispersion, but a higher attenuation […]

What is the L band DWDM?

WDM technology can be divided into WDM, CWDM, and DWDM according to different wavelength modes. The wavelength range defined by ITU-T, The CWDM range is 1271 to 1611nm based on ITU-T G 684.2. Considering the fiber attenuation of the 1270-1470nm band in the application, the band of 1470~1610nm is usually used. The channel space of […]
