DWDM networkA draft assessment, based on traffic forecasts over next five years, indicate that the majority of regional rings could be designed with SDH nodes of STM-16 line capacity (ADM-16), whereas a few regional rings would require SDH nodes of STM-64 line capacity (ADM-64). The national ring should combine DWDM technology with one or two SDH rings composed of ADM-64 nodes. The physical layer provided by local operators would be optical fibre for all rings of largest capacity, and 2.5Gbps wavelengths (STM-16) in all other rings. The topology of new regional rings would derive from CTN, with necessary changes to cope with the exact topology of the new physical layer.

Page 41


Low-cost protection based on use of OMS card after transponder (R3.0): Optical splitter: => to split the signal after WDM Tx Optical switch: => to select the signal before WDM Rx (LOS-based switch)

Only protects channel route (not transponders/optics): alternative to optical channel protection in ring networks where OMS protection cannot be used

Applicable to all transponder types: MCC3, OCC10x, WLAx, 4xAny, 2xGbE in STM-16, 8xGbE in 10G

Fault detection and switching in less than 50 ms

1696 MS: Analog Performance Monitoring

Automatic and continuous monitoring of basic optical parameters is a key to make preventive maintenance effective for WDM networks, since laser and fiber degradation are actually long-term phenomena which can be detected and addressed well in advance with respect to impacts on the carried traffic

1696 MS supports analog PMs via the 1353 NM

Page 48


Power level monitoring started from NE USM (action at Board level): for input/output power levels on transponders (Rx, Tx, client & line sides), mux/demux, amplifiers …

1353NM is in charge to sample and store input/output power values in the PM DataBase

PM Data Storage: a dedicated repository for analog monitoring, containing NEs and Monitoring Points to be selected for Report generation (Table/Chart)

PM Data Storage Query set supported 15min & 24hr sampling periods Export to OSS through 1359IOO supported
