| Basic function | LDX converts signals as follows: - 2 x 10GE LAN/10GE WAN/STM-64/OC-192/OTU2 <-> 2 x OTU2
- 2 x 10GE LAN/OTU2e <-> 2 x OTU2e
|
| Client-side service type | 10GE LAN: Ethernet service at a rate of 10.31 Gbit/s 10GE WAN: Ethernet service at a rate of 9.95 Gbit/s STM-64/OC-192: SDH/SONET service at a rate of 9.95 Gbit/s OTU2: OTN service at a rate of 10.71 Gbit/s OTU2e: OTN service at a rate of 11.1 Gbit/s |
| OTN function | - Provides the OTU2/OTU2e interface on the WDM side.
- Supports the OTN frame format and overhead processing by referring
to the ITU-T G.709.
- Supports the PM and TCM function, and PM and TCM non-intrusive
monitoring functions for ODU2.
- Supports SM function for OTU2.
|
| WDM specification | Supports ITU-T G.694.1-compliant DWDM specifications. |
| Tunable wavelength function | Supports the tunable wavelength optical module. Equipped with this
module, the board can tune the optical signal output on the WDM
side within the range of: 80 wavelengths in C-band with the channel
spacing of 50 GHz. |
| ESC function | Supported |
| PRBS test function | Supports the PRBS function on the client and WDM sides. NOTE:The PRBS function on the client side is supported only when the
client-side service type is STM-64/OC-192, OTU2 or OTU2e. |
| LPT function | The board supports the LPT function only when the client-side
service type is 10GE LAN. |
| FEC coding | NOTE:Boards that use different FEC modes cannot interconnect with each
other. |
| Alarms and performance events monitoring | - Monitors BIP8 bytes (Bursty mode) to help locate line failures.
- Monitors B1 bytes to help locate faults.
- Monitors OTN alarms and performance events.
- Monitors parameters such as the bias current, temperature, and
optical power of the laser.
- Supports the remote monitoring (RMON) of Ethernet services (10GE
LAN).
|
| Regeneration board | The WDM-side signals from one LDX board can be regenerated by
another TN12ND2/TN52ND2/TN53ND2/TN55NO2/TN53NQ2/TN54NQ2 board. |
| ALS function | Supports the ALS function on the client side when client services
are non-OTN services. |
| Test frame | Not supported |
| Latency measurement | Not supported |
| IEEE 1588v2 | Not supported |
| Physical clock | When the board receives 10GE LAN services and the port mapping is Bit Transparent Mapping (11.1 G) on its client side, the board can support synchronous Ethernet
transparent transmission instead of synchronous Ethernet
processing. |
| Optical-layer ASON | Supported |
| Electrical-layer ASON | Not supported |
| Protection scheme | - Supports client 1+1 protection.
- Supports intra-board 1+1 protection (when working with the
OLP/DCP/QCP board).
- Supports OWSP protection.
|
| Ethernet service mapping mode | Bit Transparent Mapping(11.1G), MAC Transparent Mapping(10.7G) |
| Port MTU | 9600 bytes. That is the maximum size of the supported Jumbo frame
is 9600 bytes. |
| Loopback | WDM side | Inloop | Supported |
| Outloop | Supported |
| Client side | Inloop | Supported |
| Outloop | Supported |
