Description

SSN1SL16 overview

Huawei OSN7500 SSN1SL16 1xSTM-16 optical interface board. The SL16 can be used on the OptiX OSN equipment series to transmit and receive STM-16 optical signals. The SL16 converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SL16 converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

Valid Slots

The slots valid for the SL16 vary with the cross-connect capacity of the subrack.

The slots valid for the SL16 are as follows:

  • When the cross-connect capacity is 360 Gbit/s, the SL16 can be installed in slots 1–8, 11–18, and 26–31.

The SL16 is available in three functional versions, namely, N1, N2, and N3. The difference between the three versions is with regard to whether they support the TCM function and AU-3 services.

Description
Functional versions The SL16 is available in three functional versions, namely, N1, N2, and N3.
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 N1SL16 and N2SL16 cannot be substituted with each other.

The N3SL16 supports the board version replacement function.

  • The N3SL16 can substitute for the N1SL16.
  • When the AU-3 services are not required, the N3SL16 can substitute for the N2SL16.

After the N3SL16 substitutes for the N1SL16 or N2SL16, the configuration and service status of the N3SL16 are the same as the configuration and service status of the N1SL16 or N2SL16.

Basic functions Transmits and receives 1xSTM-16 optical signals.
Specifications of the optical interface
  • Supports different types of standard optical interfaces, namely, the L-16.2, L-16.2Je, V-16.2Je (with the booster amplifier (BA)), and U-16.2Je (with the BA and pre-amplifier (PA)). The characteristics of the optical interface of the L-16.2 type comply with ITU-T G.957 and ITU-T G.692. The characteristics of the optical interfaces of the L-16.2Je, V-16.2Je (with the BA), and U-16.2Je (with the BA and PA) types comply with the standards defined by Huawei. U-16.2Je is compatible with U-16.2.
  • Supports the output of the standard wavelengths that comply with ITU-T G.692. The U-16.2Je optical interface can be directly connected to the dense wavelength division multiplexing (DWDM) equipment.
  • The N3SL16 supports DWDM colored optical interfaces, which use LC connectors and support the transmission distances of 170 km and 640 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.
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 N2SL16 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 N2SL16/N3SL16 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 tTwo-fiber ring MSP, Four-fiber ring MSP, Linear MSP, SNCP, SNCMP, and SNCTP.
  • Supports the fiber-shared MSP and SNCP and processes two sets of K bytes. One SL16 supports a maximum of two MSP protection rings.
Maintenance features
  • Supports inloops and outloops at optical interfaces.
  • The N1SL16 supports inloops on VC-4 paths. The N3SL16 board supports inloops and outloops on 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 N2SL16 and N3SL16 support the TCM function.
  • Supports the upgrade of the board software without affecting services.
  • The N2SL16/N3SL16 board supports the TCM function.
