Salumanus is one of the first companies to reintroduce a complete network solution based on the o-band. O band is a type of optical transmission, which has significant cost saving advantages in 5G networks. After several months of testing, GBC Photonics QSFP28 optical module and multiplexer are now on the market.
The equipment using o-band transmission can help to save 50% of the network construction cost and reduce about 80% of the total cost of ownership (TCO).
Optical fiber communication is generally carried out in the wavelength region with small optical fiber transmission loss. The wavelength is divided into five bands: O -, E -, S -, C - and l -. O band or original band is the main band used for telecommunications, because it has zero dispersion. The transmission range of o band is between 1260 nm and 1360 nm, which is the basis of manufacturing lasers and detectors.
Optical modules and multiplexers are some of the earliest optical modules and multiplexers released in the telecommunications market. They enable operators to send multiple 100G transmissions over distances up to 30 kilometers, using wave multiplication (WDM) technology based on a 200 GHz grid. The company has launched 8 channel solutions and continues to research, hoping to double this number.
The detector technology adopted by QSFP28 100G o band transceiver brings another innovative feature - broadband receiver. Because of this, transceivers can be used for both single fiber and dual fiber applications and help make it easier to migrate from lower speeds to 100G.
Marcin Bala, CEO of Salumanus, said: "At present, 5G and 6G network base stations use 10G and 25G connections, but due to the growing data demand, we will soon need to upgrade these connections to 100G." "An effective and economical way is to use multiplexers and modules based on the o-band. The solution we provide at Salumanus can cover a distance of 30 kilometers, while providing the required passive infrastructure, which is easier to manage and lower energy consumption."
Similarly, the o band will benefit small and medium-sized data centers and ISP operators, which currently rely on multiple 10G connections. In these cases, the o-band solution is a practical choice for easy migration.
