Huawei OptiX OSN 9800 Line Service Processing Board TNS2N602

Basic function

Implements mutual conversion between OTN signals and two OTUC4/OTUC2 signals.

Backplane capacity

The total backplane bandwidth is 800 Gbit/s.

WDM specification

Supports the DWDM specifications.

Tunable wavelength

Supports tunable wavelengths of WDM-side optical signals in Super C band (1524 nm to 1573 nm).

FEC coding

• 400G m16QAM/400G s16QAM/400G 16QAM/200G QPSK: SDFEC4
• 200G e16QAM: SDFEC2
• 200G 16QAM/200G 16QAM-H: SDFEC

Line modulation format

• 400G m16QAM
• 400G s16QAM
• 400G 16QAM
• 200G QPSK
• 200G 16QAM
• 200G 16QAM-H
• 200G e16QAM

Typical channel spacing

• 400G s16QAM: 100 GHz + n x 6.25 GHz (n = 0, 1, 2...)
• 400G m16QAM/400G 16QAM/200G QPSK: 75 GHz + n x 6.25 GHz (n = 0, 1, 2...)
• 200G 16QAM/200G 16QAM-H: 50 GHz x n (n = 1, 2...) (Only the standard center frequency of 50 GHz is supported.)
• 200G e16QAM: 50 GHz + n x 6.25 GHz (n = 0, 1, 2...)

NOTE:

Due to large filter penalties, 400G s16QAM cannot work with the optical-layer boards with a 100 GHz channel spacing, such as TNG2D60 and TNG2M60.

OTN overhead protocol

Supports the OTN frame format and overhead processing defined by ITU-T G.709.

OTN overhead

• WDM-side OTUC4/OTUC2 layer: supports SM overhead processing.
• ODUC4/ODUC2 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

NA

Intra-board 1+1 protection

Supported

NOTE:

Supports intra-board 1+1 protection when working with 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.

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

Outband DCN

Supports communication over ESCs.

Test frame

Not supported

PRBS

Supports the PRBS function on the WDM side.

Latency measurement

Delay measurement in the WDM-side optical port direction (upstream direction) is supported.

• Supports TCM delay measurement for higher-order ODU2(e)/ODU3/ODUflex/ODU4 channels when creating higher-order cross-connections.
• When lower order ODUk cross-connections are created, PM/TCM of higher order channels and TCM delay measurement of lower order ODUk channels are supported.
• Supports PM and TCM delay measurement at the ODUCn layer.

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.
