Realizes the interconversion of the following signals:

1 x 100GE/OTU41 x OTU4

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

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

• Supports WDM side OTU4 interface.
• Adopts ITU-T G.709 recommended frame format and overhead processing.
• ODU4 layer:
  • Customer side access to 100GE, supports PM function.
  • Customer-side access to OTU4, supporting PM and TCM functions, and non-involved monitoring functions for PM and TCM layers.
• OTU4 layer: supports SM function.

Supports DWDM specifications of ITU-T G.694.1.

Wavelength-side optical signals are adjustable in the 80-wave range at 50 GHz intervals in the C-band.

Support

Supported on the client side when accessing OTU4.

WDM side support when accessing 100GE and OTU4.

Customer side: FEC coding is supported only when accessing OTU4 services, in accordance with ITU-T G.709 recommendations.

WDM side:

TN12LSC: HFEC and SDFEC coding is supported.

TN13LSC: supports HFEC2 encoding.

TN14LSC: Supports HFEC, HFEC2 and SDFEC encoding.

TN15LSC: Supports HFEC and SDFEC2 encoding.

TN17LSC: Supports SDFEC2 and HFEC PLUS encoding.

• The client side supports BIP8 monitoring for 100GE and OTU4 services (BIP8 for OTU4 is in burst mode), which can locate service faults.
• The wavelength division side supports BIP8 byte monitoring (burst mode) for OTN, which can locate line faults.
• Supports OTN performance monitoring and alarm monitoring functions.
• Provides the following monitoring functions: laser bias current monitoring, laser operating temperature monitoring, optical power monitoring, etc.

• Provides Ethernet RMON monitoring function.

• Support CD and PMD performance monitoring function.

Signals from the WDM side of the TN12LSCT01/TN14LSCT01/TN15LSCT01 boards can be trunked through other TN11LTXT01/TN54NS4T01/TN57NS4T01/TN12LTXT01 boards.

The WDM side signals of TN12LSCT11/TN14LSCT11 single boards can be relayed through other TN11LTXT11/TN54NS4T11/TN56NS4T11/TN12LTXT11 single boards.

The WDM side signal of TN13LSCT21 single board can be relayed through other TN12LTXT21/TN54NS4T21 single boards.

The WDM side signal of TN14LSCT21 single board can be trunked through other TN12LTXT21/TN54NS4T21 single boards.

WDM side signals from TN15LSCT31 single board can be trunked through other TN57NS4T31 single boards.

The WDM side signals of TN15LSCT51/TN17LSCT51 single boards can be relayed through other TN57NS4T51/TN58NS4T51 single boards.

The WDM side signals of TN15LSCT61/TN17LSCT61 single boards can be relayed through other TN57NS4T61/TN58NS4T61 single boards.

Customer side support when accessing non-OTN services.

Supported only when 100GE services are accessed on the customer side.

TN14LSC/TN13LSC/TN15LSC/TN17LSC single boards support delay measurement. You can measure the bidirectional delay of ODU layer 4 between two OTU boards, and the delay data is displayed on the network management.

When the customer side accesses OTU4 services, delay measurement is not supported.

Supported

• Supports customer-side 1+1 protection.
• Supports on-board 1+1 protection (realized with QCP or OLP or DCP single board).
