Description

SSN3SL16A overview

Huawei OSN7500 SSN3SL16A 1xSTM-16 optical interface board. The SL16A 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.

Version Description

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

Description
Functional versions The SL16A is available in the following functional versions: N3, N2, and N1. The N1SL16A and N2SL16A are discontinued.
Differences
  • Specifications of optical interfaces: DWDM colored optical interfaces.
  • Service processing: AU-3 service processing.
  • REG specifications: REG function.
  • Maintenance features: loopbacks on VC-4 paths and TCM function.
Substitution
  • The N1SL16A and N2SL16A cannot be substituted with each other.
  • The N3SL16A supports the board version replacement function.
    • The N3SL16A can substitute for the N1SL16A.
    • When the AU-3 services are not configured, the N3SL16A can substitute for the N2SL16A.
  • After the N3SL16A substitutes for the N1SL16A or N2SL16A, the configuration and service status of the N3SL16A are the same as the configuration and service status of the N1SL16A or N2SL16A.
Valid Slots

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

The slots valid for the SL16A vary with the cross-connect capacity of the subrack. The slots valid for the SL16A are as follows:

  • When the cross-connect capacity is 360 Gbit/s, the SL16A can be installed in slots 1–8, 11–18, and 26–31.

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.
