OSN1800V equipment adopts wavelength division multiplexing technology DWDM/CWDM to achieve multi-service and fully transparent transmission function.WDM equipment is capable of multiplexing 80-channel services in a single optical fiber, i.e., it is capable of transmitting 80-wave carrier signals of different wavelengths. Transmission scheme for different line rates:

80-wave x 200/100/10Gbit/s transmission scheme (DWDM)

40-wave x 200/100Gbit/s transmission scheme (DWDM)

40-wave x 10Gbit/s transmission scheme (DWDM)

40-wave x 2.5Gbit/s transmission scheme (DWDM)

8-wave x 10Gbit/s transmission scheme (CWDM)

8-wave x 2.5Gbit/s transmission scheme (CWDM)

WDM devices are available for line rate applications with both schemes:

OTU single-board multiplexing: when the system has no centralized crossover, the OTU single-board can be used directly with the optical split-insert-multiplexing board for line transmission.

Single-board multiplexing with crossover system: when the system adopts MS-OTN system for centralized crossover, line transmission is carried out through the crossover system board cooperating with OTN branch board and OTN line board.
