Now many documents indicate that the subrack of the OptiX OSN 2500 REG is the same as the OptiX OSN 2500 subrack, but their BOM number is found to be different on site.
The BOM number is 02300571 for the REG subrack and 02300486 for a common subrack.
OptiX OSN 2500 REG subrack:
Part number 02300571

Internal english description OptiX OSN 2500, SSQ1AFBA, REG

OptiX OSN 2500 subrack:
Part number 02300486
Part description Backplane subrack-OptiX OSN 2500-SSQ1AFB-subrack
Internal english description OptiX OSN 2500,SSQ1AFB,Subrack

Pay special attention to the different BOM number of the OptiX OSN 2500 REG subrack and the OptiX OSN 2500 subrack when applying for spare parts.
The subracks of the OptiX OSN 2500 REG and the OptiX OSN 2500 are identical originally, but some changes were made later. Now their difference lies in that some unuseful connectors are removed from the REG subrack. Therefore, the BOM number is different.
