Description

SSN3SLH41 overview

The SLH41 is a line board. The SLH41 can be used on the OptiX OSN equipment series to transmit and receive STM-1/STM-4 optical signals. The SLH41 converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SLH41 converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

Valid Slots

The SLH41 must be installed in a valid slot on the subrack. Otherwise, the SLH41 fails to work normally.
The slots valid for the SLH41 vary with the cross-connect capacity of the equipment. The slots valid for the SLH41 are as follows:

When the cross-connect capacity is 360 Gbit/s, the SLH41 can be installed in any of slots 1-8, slots 11-18, and slots 26-31.

Basic functions Transmits and receives 16xSTM-1/STM-4 optical signals.
Specifications of the optical interface The STM-1/STM-4 optical module can be used, which supports the adaptive modulation (AM) technology.

  • When the STM-1 optical module is used, the standard S-1.1, L-1.1, and L-1.2 optical interfaces are supported. The optical interfaces of the S-1.1, L-1.1, and L-1.2 types comply with ITU-T G.957.
  • When the STM-4 optical module is used, the standard S-4.1 and L-4.2 optical interface is supported. The optical interface of the S-4.1 and L-4.2 type complies with ITU-T G.957.

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
  • Uses the SFP optical module.
  • Supports the detection and query of the information about the optical module.
  • Supports the single-fiber bidirectional optical module, and the single-fiber bidirectional optical module does not support loopbacks at the optical interface by using fiber jumpers.
  • Provides the ALS function. The optical interface supports the function of setting the on/off state of a laser.
Service processing
  • When the STM-1 optical module is used, the SLH41 supports VC-12 services, VC-3 services, and VC-4 services.
  • When the STM-4 optical module is used, the SLH41 supports VC-12 services, VC-3 services, VC-4 services, and VC-4-4c concatenation services.
Overhead processing
  • Processes the section overheads of the STM-1/STM-4 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 to sixteen channels of ECC communication. The first eight optical interfaces support the ECC communication in D1-D12 mode. The last eight optical interfaces support the ECC communication in D1-D3 mode.
Alarms and performance events Reports various alarms and performance events, which facilitates the management and maintenance of the equipment.
Protection schemes
Maintenance features
  • Supports inloops and outloops at optical interfaces.
  • Supports inloops and outloops on VC-4 paths.
  • Supports the warm reset and cold reset. The warm reset does not affect services.
  • Supports the query of the manufacturing information about a board.
  • Supports the in-service loading of the FPGA.
  • 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.
