Function and Feature

Description

Basic function

The LDC board on the client side receives four types of signals, which are OTU4, 100GE, FC3200, and FC1600. The LDC converts signals as follows:

200G line:

1. 2 x OTU4 <-> 2 x ODU4 <-> 1 x ODUC2 <-> 1 x OTUC2
2. 2 x 100GE <-> 2 x ODU4 (bit transparent mapping/MAC transparent mapping) <-> 1 x ODUC2 <-> 1 x OTUC2
3. 2 x 100GE <-> 2 x ODUflex (MAC transparent mapping) <-> 2 x ODU4 <-> 1 x ODUC2 <-> 1 x OTUC2
4. 2 x FC3200 <-> 2 x ODUflex <-> 1 x ODUC2 <-> 1 x OTUC2
5. 2 x FC1600 <-> 2 x ODUflex <-> 1 x ODUC2 <-> 1 x OTUC2
6. 2 x FC3200 <-> 2 x ODUflex <-> 1 x ODU4 <-> 1 x ODUC2<-> 1 x OTUC2 (supported only by TN12LDC)
7. 2 x FC1600 <-> 2 x ODUflex <-> 1 x ODU4 <-> 1 x ODUC2<-> 1 x OTUC2 (supported only by TN12LDC)

100G line:

1. 1 x OTU4 <-> 1x ODU4 <-> 1 x OTU4
2. 1 x 100GE <->1 x ODU4 (bit transparent mapping/MAC transparent mapping) <-> 1 x OTU4
3. 1 x 100GE <-> 1 x ODUflex (MAC transparent mapping) <-> 1 x ODU4 <-> 1 x OTU4
4. 2 x FC3200 <-> 2 x ODUflex <-> 1 x ODU4 <-> 1 x OTU4
5. 2 x FC1600 <-> 2 x ODUflex <-> 1 x ODU4 <-> 1 x OTU4

Client-side service type

100GE: Ethernet service at a rate of 103.125 Gbit/s

OTU4: OTN service at a rate of 111.81 Gbit/s

FC1600: SAN service at a rate of 14.025 Gbit/s

FC3200: SAN service at a rate of 28.05 Gbit/s

RTU

Supported only by TN12LDC.

OTN function

1. Supports OTUC2 or OTU4 interfaces on the WDM side.
2. Uses the frame formats and overhead processing methods defined in ITU-T G.709.
3. At the ODU4 layer:
   1. Supports PM overhead processing when 100GE services are received on the client side.
   2. Supports PM and TCM overhead processing when OTU4 services are received on the client side. This board supports non-intrusive monitoring of PM and TCM overheads.
4. Supports PM overhead processing at the ODUflex layer.
5. Supports PM overhead processing at the ODUC2 layer.
6. Supports SM overhead processing at the OTU4 layer on the client side.
7. Supports SM overhead processing at the OTUC2 and OTU4 layer on the WDM side.

Service encryption

Supported

NOTE:

Service encryption is supported only when the client-side service type of the LDC board is not OTU4.

WDM specification

Supports DWDM specifications.

Tunable wavelength function

LDC supports tunable wavelength optical modules that provide for 96 wavelengths tunable in the extended C band with 50 GHz channel spacing.

WDM-side signal spectrum width

1. 200G ePDM-e16QAM: 50GHz Flex/ 62.5GHz Flex/75GHz Flex
2. Others modulation format: 50GHz Fix.

NOTE:

The filter cost of a 50 GHz Fix WSS is greater than that of a 50 GHz Flex WSS. If the board has a flexible grid laser and supports a modulation format with 50 GHz fixed spectrum width, the modulation format supports 50 GHz flexible spectrum width by default. Similarly, if the board has a flexible grid laser and supports a modulation format with 100 GHz fixed spectrum width, the modulation format supports 100 GHz flexible spectrum width by default. Currently, only programmable boards with a signal rate of 200 Gbit/s or higher support flexible grid lasers.

ESC function

Supported

PRBS test function

Supports the PRBS function on both the client side and WDM side.

NOTE:

When only OTU4 services are received, the PRBS function is supported on the client side.

LPT function

Not supported

FEC coding

On the client side:

Supports ITU-T G.709-compliant forward error correction (FEC) on the client side when the client-side service type is OTU4.

Supports RS_FEC coding when the client-side service type is 100GE or FC3200.

On the WDM side:

T81: Supports SDFEC-R coding.

Others: Supports SDFEC and SDFEC2 coding.

NOTE:

Boards that use different FEC modes cannot interconnect with each other.

NOTE:

For FC services, only FC3200 services support RSFEC, and other FC services do not support FEC.

Alarm and performance event monitoring

Monitors BIP8 bytes (BIP8 bytes of OTU4 are in Bursty mode) for 100GE, and OTU4 services on the client side to help locate service failures.

1.  
2. Monitors OTN alarms and performance events.
3. Monitors parameters such as the bias current, temperature, and optical power of the laser.
4.  

Supports the remote monitoring (RMON) of Ethernet services.

1.  
2. Supports the monitoring of CD and PMD performance.

Regeneration board

Supported

ALS function

Supports the ALS function on the client side when client services are non-OTN services.

Test frame

Supported only when the client-side service type is 100GE.

Latency measurement

Supports PM and TCM latency measurement.

Supports PM and TCM latency measurement for upstream higher-order ODU channels.

Supports PM and TCM latency measurement for upstream lower-order ODU channels when non-OTN services are received on the client side.

Supports TCM latency measurement for downstream lower-order ODU channels when OTN services are received on the client side.

NOTE:

In a mapping path, the maximum granularity ODUk channel is the higher-order ODU channel, and other ODUk channels are lower-order ODUk channels.

IEEE 1588v2

Not supported

Physical clock

The board supports synchronous Ethernet transparent transmission instead of synchronous Ethernet processing in bit transparent mapping mode.

Electrical-layer ASON

Not supported

Optical-layer ASON

Supported

NOTE:

In versions earlier than V100R013C10SPC500, ASON is not supported in high SOP mode. In V100R013C10SPC500 and later versions, only ASON without optical parameters is supported in high SOP mode.

Ethernet service mapping mode

Bit Transparent Mapping ODU4, MAC Transparent Mapping ODU4, MAC Transparent Mapping ODUFlex

Protection scheme

1. Supports client 1+1 protection.
2. Supports intra-board 1+1 protection (when working with the OLP/DCP/QCP board).
3. When a QSFP28-100G(4x25G)-850nm(SR4)-MMF-0.1km module or an 112.2 Gbit/s Multirate-0.1km-QSFP28 module is used on the client side, the LDC board does not support client 1+1 protection.
4. When 100GE services are received on the client side, client 1+1 protection supports bidirectional switching rather than unidirectional switching. When OTU4 services are received on the client side, client 1+1 protection supports unidirectional switching.
