Description

TNS2N401 overview

TNS2N401 supports 1*100Gbit/s Universal Line Service Processing Board applied to Huawei OptiX OSN 9800 U64/U32/U16.

The TNS2N401 board is a hybrid line board and supports a mixture of OTN, SDH services.

The N401 board processes and converts the received service signals into one OTU4 signal. The OTU4 signals are carried over ITU-T G.694.1-compliant DWDM wavelengths.

The TNS2N401 board uses coherent receiving technologies and applies to coherent systems.

An optional version of the TNS2N401 is the TNS9N401.

Item	TNS2N401
OTN functions	Supports the OTU4 interface on the WDM side. Supports the OTN frame format and overhead processing defined in 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	The board supports tunable wavelengths of WDM-side optical signals in Super C band (1524 nm to 1573 nm).
PRBS test function	Supports the PRBS function on the WDM side.
FEC coding	Supports SDFEC2 encoding
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 from an N401/N402/N404 board can be regenerated by another N401/N402/N404 board of the same type.
Latency measurement	The board supports latency measurement in the WDM-side optical port direction (upstream direction). When higher-order ODU4 cross-connections are created on the line board, TCM section latency measurement is supported for higher-order ODU4 channels. When lower-order ODUk cross-connections are created on the line board, PM/TCM section latency measurement is supported for higher-order ODU4 channels, and TCM section latency measurement is supported for lower-order ODUk channels.
Test frame	Not supported
Physical clock	Supported (ODU0/ODU1/ODU2/ODU2e/ODU3/ODUflex)
IEEE 1588v2	Not supported
ITU-T G.8275.1	Not supported
ITU-T G.8273.2	Not supported
Electrical-layer ASON	Supported
Optical-layer ASON	Supported NOTE: In versions earlier than V100R007C00SPC500, ASON is not supported in high SOP mode. In V100R007C00SPC500 and later versions, only ASON without optical parameters is supported in high SOP mode.
Protection schemes	Supports ODUk SNCP. Supports tributary SNCP protection. Supports intra-board 1+1 protection (when working with the OLP or DCP board). NOTE: When the cross-connect granularity is ODUflex, the board does not support tributary SNCP protection.
Loopback	WDM-Side Loopback		Supported
	Channel Loopback		ODUk (k = 0, 1, 2, 2e, 3, or flex) channel loopbacks
ESC	Supported
