| WDM Specifications | Supports DWDM specifications of ITU-T G.694.1. |
| ESC Function | Support |
| PRBS Function | Supports PRBS function on customer side and WDM side. Description: The PRBS function is supported on the customer side only when accessing STM-64/OC-192, OTU2, and OTU2e services. |
| LPT Function | The LPT function is supported only when the service type on the customer side is 10GE LAN. |
| FEC Coding | FEC coding is supported on the customer side when accessing OTU2/OTU2e services, in accordance with ITU-T G.709 recommendations. FEC coding is supported on the WDM side, complying with the recommendations of ITU-T G.709. The WDM side supports AFEC-2 encoding in accordance with the recommendations of ITU-T G.975.1.
Description: Veneers with different error correction coding cannot be docked. |
| Performance Surveillance and Alarm Monitoring | Provides BIP8 byte monitoring (burst mode) to locate line faults. Provides B1 byte monitoring to locate line faults. Supports OTN performance monitoring and alarm monitoring. Provides the following monitoring functions: laser bias current monitoring, laser operating temperature monitoring, optical power monitoring, etc. Provides Ethernet (10GE LAN) RMON monitoring function.
