Huawei OptiX OSN 9800 Programmable Line Service Processing Board TNU2N401P Overview

TNU2N401P: 1 * 100G/200G Programmable Line Service Processing Board

The N401P board can work in line or relay mode. It is a programmable line board whose WDM-side rate can be flexibly adjusted to 100G or 200G. The board can be set to support 100G or 200G on a port basis. It supports the setting of 100G or 200G when working as a line board or a regeneration board. The N401P board uses coherent detection technologies and is designated for coherent systems.

An N401P board consists of a WDM-side rate/modulation format tunable optical module, a signal processing module, a control and communication module, and a power module. When the board is set to the 100G mode, the WDM-side rate/modulation format tunable optical module automatically adjusts the rate to 100G and the modulation format to 100G ePDM-QPSK (SDFEC2), and the signal processing module also automatically adjusts the rate to 100G to process OTU4 signals. When the board is set to the 200G mode, the WDM-side rate/modulation format tunable optical module automatically adjusts the rate to 200G and the modulation format to 200G ePDM-16QAM (SDFEC), 200G_8QAM (SDFEC), or 200G_QPSK (SDFEC), and the signal processing module also automatically adjusts the rate to 200G to process OTUC2 signals.

This topic describes the N401P board parameters that can be set or queried by using the NMS.

Functions and Features of the TNU2N401P Board

Function and Feature	Description
Backplane capacity	100G line mode: The total backplane bandwidth is 100 Gbit/s. 200G line mode: The total backplane bandwidth is 200 Gbit/s.
WDM specification	Supports the DWDM specifications.
Tunable wavelength	Support tunable wavelength optical modules that provide for 96 wavelengths tunable in the extended C band with 50 GHz channel spacing.
FEC coding	100G line mode:SDFEC2 200G line mode:SDFEC
Line modulation format	100G line mode: 100G QPSK 100G QPSK wDCM 200G line mode: 200G QPSK 200G 16QAM 200G 8QAM NOTE: When using a board whose line modulation format is 200G QPSK in an 80-wavelength system with a 50 GHz spacing, set the center wavelength to the median of two adjacent standard wavelengths (that is a standard wavelength plus 25 GHz), because the board must use a 100 GHz spacing during transmission. To configure the board to work in 200G mode, you must obtain a license (1 x 100G/200G Programmable Line License).
Typical channel spacing	100G QPSK(wDCM):50GHz Fix 200G QPSK:75GHz Flex/100GHz fix 200G 16QAM:50GHz Fix 200G 8QAM:62.5GHz Flex/75GHz Flex/100GHz Fix
OTN overhead protocol	Supports the OTN frame format and overhead processing defined by ITU-T G.709.
OTN overhead	100G line mode: WDM-side OTU4 layer: supports SM overhead processing. ODUk (k=0, 1, 2, 2e, 3, 4, flex) layer: supports PM and TCM overhead processing. ODUk (k=0, 1, 2, 2e, 3, 4, flex) layer: supports non-intrusive monitoring of PM and TCM overheads. 200G line mode: WDM-side OTUC2 layer: supports SM overhead processing. ODUC2 layer: supports PM and TCM overhead processing. ODUk (k=0, 1, 2, 2e, 3, 4, flex) layer: supports PM and TCM overhead processing. ODUk (k=0, 1, 2, 2e, 3, 4, flex) layer: supports non-intrusive monitoring of PM and TCM overheads.
Intra-board 1+1 protection	Supported NOTE: Supports intra-board 1+1 protection when working with optical protection boards.
ODUk SNCP	Supported
Tributary SNCP	Supported
Electrical-layer ASON	Supported
Optical-layer ASON	Supported NOTE: The flex ASON must be enabled for the modulation formats whose channel spacing is greater than 50 GHz, including 200G 8QAM and 200G QPSK. 200G 8QAM supports only 62.5 GHz/100 GHz flex ASON. 200G QPSK supports only 75 GHz/100 GHz flex ASON. Superchannel does not support ASON. 400G dual-carrier does not support ASON.
Physical clock	Supported NOTE: When the ODU cross-connect granularity of an OTN line port is set to the maximum granularity supported by the port, physical clock synchronization is not supported. The physical clock can be used only after lower-order ODU cross-connections are configured.
IEEE 1588v2	Not supported
Outband DCN	Supports communication over ESCs.
Test frame	Not supported
PRBS	Supports the PRBS function on the WDM side.
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. The board supports PM latency measurement at the ODUC2 layer.
