​What is the means of the BW? bandwidth? and which version of the RTH380H?

Hello, dear.
BW needs to be put in a sentence to know what it means.But I'm guessing it should refer to bandwidth.
Huawei OptiX RTN 380H (the RTN 380H for short) is full-outdoor 10GE E-band microwave transmission equipment.

NOTE:
The RTN 380H has two types: RTN 380H housing the MXUI5 board and RTN 380H housing the MXXI5 board. The RTN 380H housing the MXXI5 board works in two modes: common and enhanced. When RTN 380H works in common mode, its functions are the same as the functions provided by the RTN 380H housing the MXUI5 board. Unless otherwise specified, the RTN 380H refers to the RTN 380H housing the MXXI5 board. For details about the RTN 380H housing the MXUI5 board, see RTN 380H V100R007C10 Product Documentation.
Network Positioning
The RTN 380H is generally used to provide 10 Gbit/s microwave backhaul links for base stations or for aggregation sites on a mobile network or a private network, or substitute optical fibers to transmit common public radio interface (CPRI) signals or Open Base Station Architecture Initiative (OBSAI) signal between baseband units (BBUs) and remote radio units (RRUs) in a distributed base station system.
Specifications
The RTN 380H provides high-bandwidth E-band microwave transmission and has unique advantages in maintainability.
Site Configurations
OptiX RTN 380Hs can be cascaded and therefore support 1+0, 2+0, and 1+1 site configurations.
