Huawei OptiX OSN 9800 2 Port 400G Line Service Processing Board TNS3N602 Overview

TNS3N602: 2*400G Line Service Processing Board

The TNS3N602 board is a universal line board that supports hybrid transmission of OTN and SDH services and converts received service signals into OTU signals.

The TNS3N602 board can be used as a line board or a regeneration board.

The TNS3N602 board consists of ODUk cross-connect module, OTN processing module, VC cross-connect module, SDH processing module, WDM-side optical module, control and communication module, and power supply module.

This section lists the TNS3N602 board parameters that can be set or queried by using the NMS.

The transmit and receive directions are defined in the signal flow of the TNS3N602 board. The transmit direction is defined as the direction from the backplane to the WDM side of the board, and the receive direction is defined as the reverse direction.

The following describes the signal flow in the transmit direction along with the module functions.

VC-4 signals and ODUk signals can be cross-connected through the backplane.

The VC-4 signals are received by the VC cross-connect module and sent to the SDH processing module for STM-N framing and overhead processing. The generated STM-N signals are sent to the OTN processing module.

The ODUk signals are received by the ODUk cross-connect module and directly sent to the OTN processing module.

The OTN processing module maps the STM-N signals to the payload of appropriate ODUk signals, performs OTN framing and FEC encoding of the signals, and then produces and sends OTU electrical signal to the WDM-side optical module.

The WDM-side optical module receives the OTU electrical signal from the OTN processing module, performs E/O conversion, and sends out one OTU optical signal over a DWDM wavelength through the OUT port.

Functions and Features of the TNS3N602 Board

Function and Feature	Description
Basic function	Implements mutual conversion between OTN signals and two OTUC4 signal.
Backplane capacity	The maximum capacity is 800 Gbit/s.
WDM specification	Supports the DWDM specifications.
Tunable wavelength	TNS3N602AF4: Supports wavelengths tunable in Super C band (1524 nm to 1573 nm). TNS3N602LF4: Supports wavelengths tunable in Super L band (1575 nm to 1627 nm).
FEC coding	SDFEC5
Line modulation format	400G QPSK
Typical channel spacing	400G QPSK: 150GHz+n6.25GHz (n=0,1,2...) NOTE:* Due to high filtering penalty, 400G QPSK cannot be used with 100G optical-layer boards with fixed channel spacing, such as TNG2UD40 and TNG2UM40. The optical layer corresponding to an electrical module with the minimum channel spacing greater than or equal to 150 GHz must be upgraded to V100R023C10 or later. Otherwise, the following functions will be affected: Online optical power detection based on digital optical labels. Fiber connection quality detection in the local wavelength add/drop directions based on digital optical labels.
OTN overhead protocol	Supports the OTN frame format and overhead processing defined by ITU-T G.709.
OTN overhead	WDM-side OTUC4 layer: supports SM overhead processing. ODUC4 layer: supports PM and TCM 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.
OSU	Not supported
Intra-board 1+1 protection	Supported NOTE: Supports intra-board 1+1 protection when working with the optical protection boards.
ODUk SNCP	Supported
OSUflex SNCP	Not supported
Tributary SNCP	Supported
Electrical-layer ASON	Supported
Optical-layer ASON	Supported NOTE: Only ASON without optical parameters is supported in high SOP mode. The flex ASON must be enabled for the modulation formats whose channel spacing is greater than 50 GHz.
Digital optical label	When LS Ability is enabled, the board supports loading low-frequency pilot-tone modulation signals and overheads during wavelength conversion, and can work the optical-layer board that supports the digital optical label function to detect optical power and overheads and report optical performance data.
ALS	Not supported
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
ITU-T G.8275.1	Not supported
ITU-T G.8273.2	Not supported
Outband DCN	Supports communication over ESCs.
Test frame	Not supported
PRBS	Supports the PRBS function on the WDM side.
Latency measurement	Supports latency measurement in the WDM-side optical port direction (upstream direction). The board supports PM and TCM latency measurement at the ODUCn layer. When only one ODUk granularity level exists in the mapping path, ODUk channels support only TCM latency measurement. When multiple ODUk granularity levels exist in the mapping path, ODUk channels with the smallest granularity support only TCM latency measurement, and other ODUk channels support PM and TCM latency measurement. NOTE: Each line-side port supports latency measurement for a maximum of eight channels concurrently.
Channel loopback	Supports ODUk (k=0, 1, 2, 2e, 3, 4, flex) channel inloops and outloops.
Port loopback	Supports WDM Side Loopback
Alarm and performance event monitoring	Supports the monitoring of BIP8 bytes (Bursty mode) to help locate line faults. Supports the monitoring of the laser bias current. Supports the laser temperature monitoring. Supports the optical power monitoring. Supports the monitoring of OTN alarms and performance events.
