| Basic Functions |
The LOM supports the conversion of signals:
- 8 x GE/FC100/FICON/ISC 1G1 x OTU2
- 4 x FC200/FICON Express/ISC 2G1 x OTU2
- 2 x FC400/FICON 4G1 x OTU2
- Supports mixed transmission of the above services. The sum of the bandwidth of the first 4 pairs of optical ports and the sum of the bandwidth of the last 4 pairs of optical ports must not exceed 5Gbit/s.
- The LOM single board supports the FC pull-away function to ensure that the data bandwidth does not drop when transmitting FC services over long distances. For FC100, FC200 and FC400, the maximum transmission distance of WDM side of LOM single board is 3000km.
