Huawei OSN 9800 100G Line Board TNU5N404 Overview

N404: 4 x 100 Gbit/s Line Service Processing Board

The available functional versions of the N404 board are: TNU4 and TNU5.

As an OTN line board, the N404 board converts 320 ODU0, 160 ODU1, 40 ODU2, 40 ODU2e, 8 ODU3, 4 ODU4, or 320 ODUflex signals into 4 OTU4 signals carried over 4 ITU-T G.694.1 compliant DWDM wavelength, and vice versa. Each port on the board supports a mix of ODU0, ODU1, ODU2/ODU2e, ODU3, and ODUflex signals. When using colored light modules, the TNU5N404 board can be used in coherent systems.

The THU5N404 board supports electrical cross-connections, OTN interfaces, and ESC communication.

The N404 board consists of a WDM-side optical module, signal processing module, control and communication module, and power supply module.

Only the TNU5N404 board with the colored light optical modules supports the regeneration.

The N404 board electrically regenerates four OTU4 optical signals carried over four ITU-T G.694.1 compliant DWDM wavelengths.

The optical receiver on the WDM-side optical module receives four OTU4 optical signals through the IN1-IN4 optical interfaces and converts them into four OTU4 electrical signals.

The OTN processing module performs FEC decoding, overhead processing, and FEC encoding, which is the process of reshaping, regenerating, and retiming the four OTU4 electrical signals and digitally wrapping them into OTN frames.

The OTN-framed OTU4 electrical signals are sent to the optical transmitter on the WDM-side optical module. After performing E/O conversion, the transmitter produces and sends four OTU4 optical signals carried over four ITU-T G.694.1 compliant DWDM wavelengths out the OUT1-OUT4 optical interfaces.

There are indicators and interfaces on the front panel of the N404 board.

The N404 board requires one slot in a U64/U32/U16 subrack. The N404 board requires two slots in an M24 subrack.

In addition to logical ports on the N404 board, this topic describes how the physical ports on the board are displayed on the NMS.

Dimensions of the front panel (H x W x D): 477.3 mm (18.8 in.) x 30.5 mm (1.2 in.) x 220.0 mm (8.7 in.)

Weight:

TNU4N404: 4.52 kg (9.96 lb.)

TNU5N404: 4.53 kg (9.98 lb.)

Function and Feature

Function and Feature	Description
Basic function	Supports the following service conversions: 320 x ODU0/160 x ODU1/40 x ODU2/40 x ODU2e/8 x ODU3/4 x ODU4/320 x ODUflex<->4 x OTU4 Each port on the board supports a mix of ODU0, ODU1, ODU2, ODU2e, ODU3 and ODUflex signals.
Cross-connect capabilities	Supports backplane cross-connections of 320 ODU0, 160 ODU1, 40 ODU2, 40 ODU2e, 8 ODU3, 4 ODU4, or 320 ODUflex signals from/to the cross-connect board.
OTN functions	Supports OTU4 on 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 80 wavelengths tunable in the C band with 50 GHz channel spacing. TNU5N404 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	When colored light optical modules are used: SDFEC2,HFEC PLUS When gray light optical modules are used: FEC NOTE: Boards that use different FEC modes cannot interconnect with each other.
Alarms and performance events 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	TNU4N404: Not supported TNU5N404: The WDM-side signals of a TNU5N404 board can be regenerated using the TNU5N404 board of the same optical modules. Each port supports setting relay mode. NOTE: When using the gray light optical modules, TNU5N404 does not support the regeneration.
Latency measurement	The TNU5N404 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
IEEE 1588v2	Not supported
Physical clock	TNU5N404: Supported TNU4N404: Not supported
Electrical-layer ASON	Supported
Optical-layer ASON	Supported NOTE: Optical-layer ASON is not supported when a gray light optical module is used. TNU5N404: 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 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.
