The OI4/OI4D transmits and receives STM-4 optical signals, performs O/E conversion for the STM-4 optical signals, extracts and inserts overhead bytes, and generates alarm signals on the line.
The OI4 is a 1xSTM-4 optical interface board.
The OI4D is a 2xSTM-4 optical interface board. The OI4D is available in two types: pluggable OI4D and integrated OI4D. The pluggable OI4D can be installed in slot IU1, IU2, or IU3. The integrated OI4D is integrated with the SCB. The optical port of the OI4D can be equipped with an SC connector or an SFP optical module. You can select an SC connector or an SFP optical module depending on requirements. When an SFP optical module is used, the maintenance of the optical module is convenient.
Table 1 provides the functions and features of the OI4/OI4D.
| Function and Feature | OI4 | OI4D |
|---|---|---|
| Basic functions | Transmits and receives 1xSTM-4 optical signals. | Transmits and receives 2xSTM-4 optical signals. |
| Specifications of the optical interface | Supports different types of standard optical interfaces, namely, the Ie-4, S-4.1, L-4.1, and L-4.2. The characteristics of the optical interfaces comply with ITU-T G.957. | |
| Specifications of the optical module | Provides the automatic laser shutdown (ALS) function (the 42OI4 does not provide 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. | |
| Time synchronization function | Supports the high-precision time synchronization function to realize the synchronization of time over the entire network. | |
| 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. | |
