Hand Calculation for Optical Losses and Output Optical Power required C3750

Customer would like to receive extra information (and step-by-step) regarding calculations of Optical Power for TX / RX according the information delivered at the beginning:

 

- SFP model: GLC-SX-MM

- Fiber: 62.5 micron OM1

- Aprox. 500ft distance

- 6 connections / 3 patchpannel with loss insertion of 0.75 dB each

- 3750 Switch to a 2960S Switch

 

I've already check the datasheet for the fiber:

and for the SFP:
