SSN1SF64 overview

The SF64 is a line board. The SF64 can be used on the OptiX OSN equipment series to transmit and receive STM-64 optical signals. The SF64 can achieve ultra-long distance transmission when working with the BPA and DCU board.

Valid Slots

The SF64 must be installed in a valid slot in the subrack. Otherwise, the SF64 fails to work normally.

The N1SF64 can be installed in slots 4-8, 11-16, and 26-31.
The N4SF64 can be installed in slots 1-8, 11-18, and 26-31.
Relationship between the feature code of the SF64 and the type of optical interface
Feature Code
Type of Optical Interface
SSN1SF6400, SSN4SF6400 00 Fixed-wavelength optical interface
SSN1SF6401, SSN4SF6401 01 Ue-64.2c, Ue-64.2d, and Ue-64.2e


The SF64 is available in the following functional versions: N1 and N4.
Functional versions The SF64 is available in two functional versions, namely, N1 and N4.
  • Specifications of optical interfaces: DWDM colored optical interfaces.
  • Specifications of optical modules: pluggable XFP optical modules.
  • Maintenance features: voltage monitoring and reporting, and PRBS function.
Substitution The N4SF64 supports the board version replacement function to substitute for the N1SF64.


Function and Feature
Basic functions
  • Transmits and receives 1xSTM-64 optical signals.
  • Supports the enabling or disabling of the FEC function.
Specifications of the optical interface
  • Supports different types of standard optical interfaces, namely, the Ue-64.2c, Ue-64.2d, and Ue-64.2e. The characteristics of the optical interfaces comply with the standards defined by Huawei.
  • Supports the output of the standard wavelengths that comply with ITU-T G.692 and can be directly connected to the DWDM equipment.
  • The N1SF64/N4SF64 supports the DWDM colored optical interfaces. The optical interface uses the LC connector. The DWDM optical interface supports the transmission distance of 40 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.
  • The N4SF64 supports the usage and detection of the XFP optical module, therefore facilitating maintenance 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, VC-4-16c concatenation services, and VC-4-64c concatenation services.
Overhead processing
  • Processes the section overheads of the STM-64 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.
Specifications of the REG
  • 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 and the FEC 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 SF64 supports a maximum of two MSP rings.
Maintenance features
  • Supports inloops and outloops at optical interfaces.
  • 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.
  • Supports the upgrade of the board software without affecting services.
  • Supports the press-to-collect function in fault data collection.
  • The N4SF64 supports detection and query of the voltage.
  • Supports the PRBS function. For details, see Availability.
