Huawei OSN 3500 SDH Board SSN3SL16A Overview

SL16A :1xSTM-16 optical interface board

The SL16A is available in the following functional versions: N3, N2, and N1. The N1SL16A and N2SL16A are discontinued.

The SSN3SL16A is a line board. The SL16A can be used on the OptiX OSN equipment series to transmit and receive STM-16 optical signals. The SL16A converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SL16A converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

The SL16A receives and transmits 1xSTM-16 optical signals, processes overhead bytes, and performs the MSP.

The SL16A consists of the O/E converting module, MUX/DEMUX module, SDH overhead processing module, logic and control module, and power module.

The front panel of the SL16A has indicators, interfaces, a bar code, a laser safety class label, and an APD alarm label.

The SL16A does not have any jumpers or DIP switches that are used for board settings.

The SL16A must be installed in a valid slot in the subrack. Otherwise, the SL16A fails to work normally.

Functions and Features

Function and Feature	Description
Basic functions	Transmits and receives 1xSTM-16 optical signals.
Specifications of the optical interface	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.
Specifications of the optical module	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, VC-4-4c concatenation services, VC-4-8c concatenation services, and VC-4-16c concatenation services. The N2SL16A supports the AU-3 services.
Overhead processing	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.
Alarms and performance events	Reports various alarms and performance events, which facilitates the management and maintenance of the equipment.
Specifications of the REG	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.
Protection schemes	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.
Maintenance features	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.
