Description

SST2SL64 overview

The SL64 is a line board. The SL64 can be used on the OptiX OSN equipment series to transmit and receive STM-64 optical signals. The SL64 converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SL64 converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

Versions of the SL64
Item
Description
Functional versions The SL64 is available in the following functional versions: N1, N4 and T2.
Differences
  • The T2SL64 does not support the board version replacement function, but supports the TCM function and AU-3 services, the TCM function and AU-3 services cannot be available at the same time.
  • The N1SL64/N4SL64 supports the board version replacement function, but does not support the TCM function or AU-3 services.
  • The N4SL64 supports pluggable XFP optical modules.
  • The N4SL64 detects and reports voltage performance.
  • SL64 boards of different versions support different loopback functions. For details, see Functions and Features.
Substitution When the TCM function and AU-3 services are not required, the N1SL64 can substitute for the T2SL64.

When the TCM function and AU-3 services are not required, the N4SL64 can substitute for the T2SL64.

The N4SL64 supports the board version replacement function to substitute for the N1SL64.
