1xSTM-4 Optical Interface Board(S-4.1,LC)

Substitute for SSN1SL4(S-4.1,LC).

Apply to Huawei OSN 1500B, OSN 2500, OSN 3500, OSN 7500 to transmit and receive 1xSTM-4 optical signals, at 2~15km.

Supports the detection and query of the information about the optical module.

Supports ALS function. The optical interface supports the setting of the on/off state of a laser.

Supports the usage and monitoring of SFP optical module, which facilitates maintenance and upgrading of optical module.

Supports the single-fiber bidirectional optical module.

Supports the VC-12, VC-3, VC-4 services, and VC-4-4c concatenation services.

Supports the transparent transmission and termination of the path overheads.

Supports the setting and query of the J0, J1, and C2 bytes.

Supports one channel of ECC communication.

Supports the two-fiber ring MSP, four-fiber ring MSP, linear MSP, SNCP, SNCTP, and SNCMP protection schemes.

Supports the fiber-shared MSP and SNCP and processes two sets of K bytes.

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.
