HUAWEI SL16A SSN3SL16A(L-16.1,LC) SSN3SL16A08-STM-16 Optical Interface Board

Supports different types of standard optical interfaces, namely, the I-16, S-16.1, L-16.1, and L-16.2. The characteristics of the optical interfaces comply with ITU-T G.957 and ITU-T G.692.

The N3SL16A supports U-16.2Je (with the BA and pre-amplifier (PA)). The characteristics of the optical interfaces of the U-16.2Je (with the BA and PA) comply with the standards defined by Huawei. U-16.2Je is compatible with U-16.2.

The N3SL16A supports the CWDM and DWDM colored optical interfaces. The optical interface uses the LC connector. The CWDM optical interface supports the transmission distance of 80 km, and the DWDM optical interface supports the transmission distance of 120 km.

• 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.

• Supports the VC-12 services, VC-3 services, VC-4 services, VC-4-4c concatenation services, VC-4-8c concatenation services, and VC-4-16c concatenation services.
• The N2SL16A supports the AU-3 services.

• Processes the section overheads of the STM-16 signals.
• 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.

• The N2SL16A/N3SL16A board supports the setting and query of the REG working mode.
• With the REG function enabled, the board is in RS loopback mode and processes only the regeneration section overhead.

• Supports the Two-fiber ring MSP.
• Supports the Four-fiber ring MSP.
• Supports the Linear MSP.
• Supports the SNCP.
• Supports the SNCMP.
• Supports the SNCTP.
• Supports the fiber-shared virtual trail protection.
• Supports the fiber-shared MSP and processes two sets of K bytes. One SL16A supports a maximum of two MSP rings.

• Supports inloops and outloops at optical interfaces.
• The N1SL16A supports inloops on VC-4 paths. The N3SL16A board 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.
• The N2SL16A/N3SL16A board supports the TCM function.
• Supports the upgrade of the board software without affecting services.
• Supports the PRBS function. For details, see Availability.
• Supports the press-to-collect function in fault data collection.
• Hot board swapping.
