All productsHuawei OptiX OSN 8800 is a high-performance, intelligent optical transport platform used for building next-generation telecommunication networks. A crucial component of this platform are the Optical Transponder (OTU) boards responsible for converting client-side services (Ethernet, SDH, etc.) into standard optical signals for transmission over fiber optic cables.
The OSN8800 offers various OTU boards catering to different needs and speeds:
- OTU2 boards: Support 10G Ethernet or 10G SDH services and are ideal for cost-effective short-haul and metro network applications.
- OTU4 boards: Handle 100G Ethernet or 100G SDH services, delivering high bandwidth for data center backhauls and long-haul networks.
- OTUC boards: These cutting-edge boards offer support for future 400G Ethernet and 400G SDH services, future-proofing your network infrastructure.
Now, we will introduce the LSC boards on Huawei OSN8800, which is a wavelength conversion board and applies to coherent systems. In the receive direction, the board receives one 100GE/OTU4 optical signal from the client equipment, maps the optical signal into an OTU4 signal, and converts the OTU4 signal into a standard WDM wavelength.
There are different versions of LSC boards, TN12, TN13, TN15, TN17, TN18 and TN19. The mappings between the board and equipment are as below:
| Board | Initial Versiona(a) | General 8800 T64 Subrack | Enhanced 8800 T64 Subrack | General 8800 T32 Subrack | Enhanced 8800 T32 Subrack | 8800 T16 Subrack | 8800 Universal Platform Subrack | 6800 Subrack | 3800 Chassis |

And the board substitution relation among different versions as below:
| 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. In an OptiX OSN 6800 subrack, the TN12LSC board cannot be replaced with the TN15LSC board. |
