1*100G Line Service Processing Board
| Functions and features (line mode) | |
| Basic function | Supports the following service conversions: 80 x ODU0/40 x ODU1/10 x ODU2/10 x ODU2e/2 x ODU3/1 x ODU4/80 x ODUflex <-> 1 x OTU4 Supports a mix of ODU0, ODU1, ODU2, ODU2e, ODU3, and ODUflex signals. |
| Cross-connect capabilities | Supports backplane cross-connections of 80 ODU0, 40 ODU1, 10 ODU2, 10 ODU2e, 2 ODU3, 1 ODU4, or 80 ODUflex signals from/to the cross-connect board. |
| OTN functions | Supports OTU4 interface the WDM side. Supports the OTN frame format and overhead processing defined by ITU-T G.709. OTU4 layer: supports SM overhead processing. ODUk (k=0, 1, 2, 2e, 3, 4, flex) layer: supports PM and TCM overhead processing, and non-intrusive monitoring of PM and TCM overheads. |
| WDM specification | Supports ITU-T G.694.1-compliant DWDM specifications. |
| Tunable wavelength function | Supports tunable wavelength optical modules that provide for 96 wavelengths tunable in the extended C band with 50 GHz channel spacing. |
| ESC function | Supported |
| PRBS function | Supports the PRBS function on the WDM side. |
| FEC coding | CFP-100G(4x25G/28G,Dualrate)-1295nm to 1310nm(LR4)-SMF-10km-SP modules: FEC Other modules: SDFEC2 Boards that use different FEC modes cannot interconnect with each other. |
| Alarm and performance event monitoring | Monitors BIP8 bytes (Bursty mode) to help locate line failures. Monitors parameters such as the bias current, temperature, and optical power of the laser. Monitors OTN alarms and performance events. |
| Regeneration board | The WDM-side signals of an N401 board can be regenerated using the N401, M402 board of the same type. For example, |
| The type of the TNG1N401C01 board is C01, and the WDM-side signals of the TNG1N401C01 board can be regenerated using the N401, M402 board of the C01 type, such as TNG1N401C01, TNG1M402C01. | |
| Latency measurement | The board supports latency measurement in the WDM-side optical port direction (upstream direction). When higher-order ODUk cross-connections are created on the line board, TCM section latency measurement is supported for higher-order ODUk channels. When lower-order ODUk cross-connections are created on the line board, PM/TCM section latency measurement is supported for higher-order ODUk channels, and TCM section latency measurement is supported for lower-order ODUk channels. |
| Physical clock | Supported |
| Electrical-layer ASON | Supported |
| Protection scheme | Supports ODUk SNCP. Supports tributary SNCP protection. Supports intra-board 1+1 protection (when working with the OLP/DCP/QCP board). Note: When the cross-connect granularity is ODUflex, the board does not support tributary SNCP protection. |
| Loopback | Supported |
| Functions and features (rely mode) | |
| Basic function | Electrically regenerates optical signals at an electrical REG station. |
| Supported service rate | OTU4: OTN service at a rate of 111.81 Gbit/s |
| OTN function | Supports OTU4 interface the WDM side. Supports the OTN frame format and overhead processing defined by ITU-T G.709. OTU4 layer: supports SM overhead processing. ODU4 layer: supports PM and TCM overhead processing, and non-intrusive monitoring of PM and TCM overheads. |
| WDM specification | Supports ITU-T G.694.1-compliant DWDM specifications. |
| Tunable wavelength function | Supports tunable wavelength optical modules that provide for 96 wavelengths tunable in the extended C band with 50 GHz channel spacing. |
