SSR1PCXLL401 is a SDH service board which serve in Huawei OSN 1500B equipment. You could discover several names of this board, these are SSR1PCXLL4, SSR1PCXLL401, SSRD0PCXL411. In fact they describe the same item and you can use any name of it to search on the internet. Many professional HUAWEI transmission product suppliers buy this board such as thunder-link international. Reports various alarms and performance events, which facilitates the management and maintenance of the equipment.
Four parts compose of SSR1PCXLL401, namely, SDH Processing Unit whose function is transmits and receives 1xSTM-1/STM-4/STM-16 optical signals; SCC Unit works on Configures and monitors services, monitors the service performance,and collects the information about the performance events and alarms; Cross-Connect Unit includes Higher order cross-connect capacity: 60(Gbit/s); Lower order cross-connect capacity: 20(Gbit/s), which matters a lot to the customers; the forth one Clock Unit provides the standard system synchronization clock.
The SSR1PCXLL401 is available in one functional version, that is R1. It is used in the OSN 1500B Transmits and receives 1xSTM-1/STM-4/STM-16 optical signals. It converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, it also converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.
The SSR1PCXLL401 could be installed in slots 4 and 5 in the subrack. By default, slot 4 is the slot for the working board, and slot 5 is the slot for the protection board.
The feature code 401 of the SSR1PCXLL401 indicates the type of optical interface is S-4.1. Some parameters that differ from the series board of SSR1PCXLL401 can be referred as follows: (S-4.1) , its transmission distance is 2 ~ 15 km; (L-4.1 ), 20~40km; (L-4.2), 50~80km and (Ve-4.2 ), 50~100km.
