a: When the TN19LSC board is installed in an OSN 6800 subrack, the first generation T5U, T62, and T65 pluggable modules without heat dissipation holes are not supported.

b: To use a TN12LSC/TN13LSC/TN15LSCT01 board in the OptiX OSN 3800 chassis, meet the following requirements:

  • TN12LSC: The OptiX OSN 3800 chassis can be DC powered. The air intake vent temperature of the chassis is within the range of 5°C (41°F) to 45°C (113°F) during long-term operation and is within the range of -5°C (23°F) to 50°C (122°F) during short-term operation.
  • TN13LSC: The OptiX OSN 3800 chassis can be AC or DC powered, and the operating temperature requirements of the chassis using TN13LSC are the same as those of the chassis using TN12LSC. The OptiX OSN 3800 chassis can be equipped with at most one TN13LSCT11 board or two TN13LSCT01 boards.
  • TN15LSCT01: The OptiX OSN 3800 chassis can be AC or DC powered and has no special requirements on the operating temperature. It can be equipped with at most one TN15LSCT01 board.
  • TN12LSC/TN13LSC/TN15LSCT01: The system control board TN23SCC must be configured.

Variants

NOTE：

  • The boards using different optical line modulation formats, such as QPSK, QPSK wDCM, and QPSK wDCM-Enhanced, cannot be interconnected. For example, T51 using QPSK cannot be interconnected to T61 using QPSK wDCM.
  • T6x supports the setting of parameter AFEC Grade. Interconnection is supported only when parameters AFEC Grade at two ends are set to the same value. The T6x boards are sorted by transmission distance in the following sequence: T61 > T62 > T65. When different types of boards are interconnected, the actual short-haul transmission distance prevails.
  • The boards using different error correction coding modes, such as HFEC, SDFEC, and SDFEC2, cannot be interconnected.

 

Available variants of the TN17LSC board

Variant WDM-Side Fixed Optical Module FEC Encoding
T50 150000 ps/nm-C Band-Tunable Wavelength-ePDM-QPSK (SDFEC2, Enhanced)-PIN SDFEC2
T51 150000 ps/nm-C Band-Tunable Wavelength-ePDM-QPSK (SDFEC2)-PIN SDFEC2
T52 55000 ps/nm-C Band-Tunable Wavelength-ePDM-QPSK (SDFEC2)-PIN SDFEC2
T53 40000 ps/nm-C Band-Tunable Wavelength-ePDM-QPSK (SDFEC2)-PIN SDFEC2
T61 150000 ps/nm-C Band-Tunable Wavelength-ePDM-QPSK (SDFEC2, wDCM)-PIN SDFEC2
T62 40000 ps/nm-C Band-Tunable Wavelength-ePDM-QPSK (SDFEC2, wDCM, LH)-PIN SDFEC2
T65 12000 ps/nm-C Band-Tunable Wavelength-ePDM-QPSK (SDFEC2, wDCM-Metro)-PIN SDFEC2
T58 120000 ps/nm-C Band-Tunable Wavelength-ePDM-QPSK (SDFEC2)-PIN SDFEC2
T68 120000 ps/nm-C Band-Tunable Wavelength-ePDM-QPSK (SDFEC2, wDCM)-PIN SDFEC2

NOTE:

The T65 variant of the TN17LSC board applies to metro networks, and its WDM-side module requires the use of the same wavelength at the transmit and receive ends and does not support wavelength change by configuring regeneration boards.

Substitution Relationship

Original Board Substitute Board Substitution Rules
TN12LSC TN13LSC

TN15LSC

 TN13LSC can be created as 12LSC on the NMS. The former can substitute for the latter, without any software upgrade. After the substitution, the TN13LSC board functions as the TN12LSC board.

TN15LSC can be created as 12LSC on the NMS. The former can substitute for the latter, without any software upgrade. After the substitution, the TN15LSC board functions as the TN12LSC board.

A TN13LSC/TN15LSC board occupies two slots, and a TN12LSC board occupies four slots. To use a TN13LSC/TN15LSC board to substitute for a TN12LSC board, install the TN13LSC/TN15LSC board into the left-side slot of the four slots that the TN12LSC board originally occupies and keep the right-side slot of them vacant.

NOTE:

When both the receive and transmit boards use HFEC, the TN12LSC board can be replaced with the TN15LSC board.

In an OptiX OSN 6800 subrack, the TN12LSC board cannot be replaced with the TN13LSC board.
