Huawei OptiX OSN 9800 OTM Nodes apply to terminal sites. An OTM node can be either an 80-wavelength or a 40-wavelength system. 80-wavelength system: When serving as an 80-wavelength system, an OTM node optical multiplexer, demultiplexer, and ITL boards. The OTM node can be expanded to provision 80 wavelengths without interrupting services. 40-wavelength system: When serving as a 40-wavelength system, an OTM node optical multiplexer and demultiplexer boards. The OTM node can be expanded to provision 40 wavelengths without interrupting services. Signal Flow In the receive direction: The line signal received from west is separated into an optical supervisory signal and a main-path optical signal. The optical supervisory signal is sent to the optical supervisory channel (OSC) board for processing, and the main-path optical signal is sent to an amplifier board for amplification. The ITL board splits the amplified main-path optical signal into a C_EVEN multiplexed ...

As a one-box product (OTN+OCS), the equipment integrates functions such as WDM transport, ROADM, 40G, electrical T-bit cross-connection, cross-connections of any granularity in the range of 100M to 40G, ASON, and rich management and protection. Transmission Equipment with High Integration and Ultra Capacity The equipment is of high integration, which enables flexible service configuration. A network built with the equipment is easy to design, to expand, and to maintain, and requires a smaller number of spare parts. The equipment supports access of massive services and centralized cross-connections and management of the services. This avoids assembly of multiple subracks. The equipment is of high integration. For example, one PID chip is integrated with tens of photoelectric components to achieve 12 x 10G transmission. When used as an 80/40-channel system, the OptiX OSN 8800 supports:  * Service access over one channel of 2.5 Gbit/s, 10 Gbit/s, 40 Gbit/s.  * Tra...
