2 x 10 Gbit/s wavelength conversion unit Board
| Function and Feature | Description | ||
|---|---|---|---|
| Basic function | LDX converts signals as follows:
| ||
| 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 |
| ||
| 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 |
| ||
| Regeneration board | The WDM-side signals from one LDX board can be regenerated by another ND2/NQ2/N210/N216 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 |
| ||
| Ethernet service mapping mode | Bit Transparent Mapping(11.1G), MAC Transparent Mapping(10.7G) | ||
| Loopback | WDM side | Inloop | Supported |
| Outloop | Supported | ||
| Client side | Inloop | Supported | |
| Outloop | Supported | ||
Protocol or standard compliance | Protocols or standards (non-performance monitoring) with which transparently transmitted services comply | IEEE 802.3ae ITU-T G.707 ITU-T G.782 ITU-T G.783 GR-253-CORE Synchronous Optical Network (SONET) Transport Systems: Common Generic | |
Protocols or standards (performance monitoring) for processing services | ITU-T G.805 ITU-T G.806 ITU-T G.709 ITU-T G.872 ITU-T G.7710 ITU-T G.798 ITU-T G.874 ITU-T M.3100 ITU-T G.874.1 ITU-T G.875 ITU-T G.808.1 ITU-T G.841 ITU-T G.8201 ITU-T G.694.1 | ||
| Board | WDM-Side Optical Module | Typical Power Consumption (W) | Maximum Power Consumptiona (W) |
|---|---|---|---|
| LDX | 800 ps/nm-C Band (Odd & Even Wavelengths)-Fixed Wavelength-NRZ-PIN-XFP | 44.5 | 51.2 |
| 800 ps/nm-C Band-Tunable Wavelength-NRZ-PIN-XFP | 45.5 | 52.2 | |
| a: The maximum power consumption is the power consumed by the board when it works normally under the highest ambient temperature. | |||
