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.
| Function and Feature | SB2D | SB2R | SB2L |
|---|---|---|---|
| Basic functions | Transmits and receives 2xSTM-1 optical signals. | Transmits and receives 1xSTM-1 optical signals. | Transmits and receives 1xSTM-1 optical signals. |
| Specifications of the optical interface | Supports different types of standard optical interfaces, namely, the S-1.1 and L-1.1. The characteristics of the optical interfaces comply with ITU-T G.957. | ||
| Specifications of the optical module | Uses the SC optical module. Provides the ALS function. The optical interface supports the function of setting the on/off state of a laser. | ||
| Service processing | Supports the processing of the VC-12, VC-3, and VC-4 services. | ||
| Overhead processing |
| ||
| Pointer processing | Processes the AU pointer. | ||
| Alarms and performance events | Provides rich alarms and performance events, thus facilitating the management and maintenance of the equipment. | ||
| Protection modes | Supports the SNCP. | ||
