CRITICAL INSTRUCTIONS:
|
|
1. Look at the most prominent text (usually top 1-2 rows). This is the product NAME and MODEL.
|
|
2. Extract the PART NUMBER (P/N, Model No, Type). If no explicit Part Number is found, synthesize one from the most unique identifier in the header (e.g. 'OM4-MMF-DX').
|
|
3. Separate the COLOR (e.g. Turquoise, Yellow, Black).
|
|
4. Extract CATEGORY based on the item type (e.g. Patchcord, SFP, Connector).
|
|
5. Extract technical SPECS (e.g. '2.0mm', '10G', '850nm').
