All productsHuawei OSN 9800 supports several 10G 40G 100G and 200G Universal Line Service Processing Boards,such as 10G TNV1N210 TNV1N220, 40G TNV1N302 TNU1N302, 100G TNU1N402 TNU2N402; There are different functional versions of these boards, for example 100G U401 board has four functional versions: TNU2, TNU3, TNV2, and TNU4. They all supported by the OptiX OSN 9800 U64/U32/U16, but they are different in functions features and appearance, this article will mainly introduce the comparison of TNU2U401, TNV2U401, TNU3U401 and TNU4U401.
Different Appearance：
TNU2U401, TNV2U401, TNU3U401 and TNU4U401 are fixed optical module, but TNU4U401 is pluggable optical module.
1. Front panel of TNU2U401, TNV2U401, or TNU3U40
2. Front panel of TNU4U401
Different Functions and Features:
1. Different service supported
TNU3U401/TNU4U401 support a mixture of OTN, SDH, and packet services.
TNU2U401 and TNV2U401 supports a mix of OTN and packet services.
Application scenario for example: mixed transmission of OTN, SDH, and packet services
2. Initial Version, FEC coding, SDH Service
All firmware should be provided by the client and obtained from legally authorized way.

Cross-connect board: U64 Standard: TNV1XCS/TNV2XCS/TNU2UXCS U32 Standard: TNV1XCS/TNV2XCS/TNU2UXCS U16: TNS1XCS/TNS1UXCS |
| TNU3U401 | Cross-Connect Board: U64 Standard: TNU2UXCS U32 Standard: TNU2UXCS U16: TNS1UXCS |
||
| TNU4U401 | The TNU4U401 board must work with a TNU2UXCS or TNS1UXCS board | ||
| TNU4U401 and TNU3U401 can work with SXCL boards to groom VC-3/VC-12 services, and the SXCL must be used with TNU2UXCS/TNS1UXCS board | |||
Different WDM-side modules supported
