The unceasing demand for Internet-based services makes carrier IP networks a more critical social infrastructure. Operators are required to offer higher speeds, larger capacities and higher reliability network. There emerge two solutions to tackle this issue: IP/WDM and IP/OTN. IP/WDM … Continue reading
Coarse Wavelength Division Multiplexing (CWDM) has proven itself to be a preferred approach to elevate the bandwidth of optical access networks, offering quicker and simpler installation and lower overall cost. Passive CWDM, which requires no electrical power at all, is … Continue reading
Raman amplifier is appearing to be a critical technology which is consistently developed for using in optical communication networks. Typically applied in long-haul networks, Raman amplifier is also expected to extend its reach in dense wavelength-division multiplexing (DWDM) networks. This … Continue reading
WDM technology is commonly used in today’s optical network. It basically assigns each service (10G LAN, SONET/SDH, Fiber Channel, etc) an independent dedicated wavelength—which then is multiplexed into one single fiber. Eliminating the use of multiple fibers while increasing fiber capacity, … Continue reading
An optical network that involves WDM (wavelength division multiplexing) currently gains in much popularity in existing telecom infrastructure. Which is expected to play a significant role in next-generation networks to support various services with a very different requirement. WDM technology, … Continue reading
What Is WDM Firstly, we will answer the question: what is WDM? WDM (Wavelength-division Multiplexing) is the technology of combing a number of wavelengths onto the same fiber simultaneously. A powerful aspect of WDM is that each optical channel can … Continue reading
