The SB2D/SB2R/SB2L transmits and receives STM-1 optical signals on a single fiber, performs O/E conversion for the STM-1 optical signals, extracts and inserts overhead bytes, and generates alarm signals on the line.
The SB2R and SB2L must be used together.
Table 1 provides the functions and features of the SB2D/SB2R/SB2L.
