What is LPO (Linear-drive Pluggable Optics)?

LPO is short for Linear Pluggable Optics (or Linear-drive Pluggable Optics), it is a potential technology to satisfy the low power consumption and high bandwidth demand of data centers like CPO (Co-packaged Optics). Currently, IPEC (The International Photonics & Electronics Committee) is focusing on cutting-edge optoelectronic technologies. Image source from LightCounting The following are the […]

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 […]
