SSN1SLD4A10
SSN1SLD4A(S-4.1), SSN1SLD4A20
The SSN1SLD4A10 is a line board. The SSN1SLD4A10 can be used on the OptiX OSN 1500B, OSN 2500, OSN 3500, OSN 7500 equipment to transmit and receive STM-4 optical signals
S-4.1, 15km
| Basic Functions | Receives and transmits 2xSTM-4 optical signals, and processes 2xSTM-4 standard or concatenation services. |
| Optical Interface Specifications |
Supports different types of standard optical interfaces, namely, the I-4, S-4.1, L-4.1, L-4.2, and Ve-4.2. The characteristics of the optical interfaces of the I-4, S-4.1, L-4.1, and L-4.2 types comply with ITU-T G.957. The characteristics of the optical interface of the Ve-4.2 type comply with the standards defined by Huawei. Here the SSN1SLD4A(S-4.1,LC) transmit distance is 2~15km. |
| Optical Module Specifications |
Supports the detection and query of the information about the optical module. Provides the ALS function. The optical interface supports the setting of the on/off state of a laser. Supports the usage and monitoring of the SFP optical module, which facilitates the maintenance and upgrading of the optical module. |
| Service Processing | Supports the VC-12 services, VC-3 services, VC-4 services, and VC-4-4c concatenation services. |
| Overhead Processing |
Processes the section overheads of the STM-4 signals. Supports the transparent transmission and termination of the path overheads. Supports the setting and query of the J0, J1, J2, and C2 bytes. Supports one or two channels of ECC communication. |
| Alarms and Performance Events | Reports various alarms and performance events, which facilitates the management and maintenance of the equipment. |
| Protection Schemes |
Supports the two-fiber ring MSP, four-fiber ring MSP, linear MSP, SNCP, SNCTP, and SNCMP. Supports the fiber-shared MSP and SNCP and processes four sets of K bytes. A single optical interface supports two MSP protection rings, and one SSN1SLD4A(S-4.1,LC) supports a maximum of four MSP protection rings. |
| Maintenance Features |
Supports inloops and outloops at optical interfaces. Supports inloops and outloops on VC-4 paths. Supports warm resets and cold resets. The warm reset does not affect services. Supports the query of the manufacturing information of the board. Supports the in-service loading of the FPGA. Supports the upgrade of the board software without affecting services. Supports the press-to-collect function in fault data collection. |
