TIDA-00725: OTDR specifications

Hi Ankur,

This reference design is a proof of concept intended to aid you in your design process. It is not fully characterized in the same manner as commercially available measurement equipment.

As per the document TIDA-00725, computations(averaging of samples) have been done on PC but we would be using a microcontroller/microprocessor for this purpose.

1) Pl suggest us one which would be able to handle these computations and can interface with a LCD display.

2) Or, Would you suggest doing these computations in the FPGA's DSP block.

Hi Ankur,

I'm forwarding this thread over to our embedded experts, they should be able to help you with a MCU solution.

Hello Ankur,

I am wondering if you could please provide us with more information on your requirements. From the processor perspective, what IPs are you looking for and what type of functionality are you looking for? Are you planning on running Linux or RTOS?

Could you at least let me know how long fiber can be tested with this design?

I am trying to rephrase my question to make it more relevant to you.

How many samples from ADC have been collected per pulse launched into the fiber?  And then how many such pulse repetitions have been averaged to show the results as given in figure 33 on page 28 of the above document i.e. TIDUAZ1.

Hello Ankur,

Krunal and I are from the processors team. Since it sounds like you are no longer asking about the microprocessor side of the design, we are going to send your thread back to the ADC team to see if they can give you more details about the TI Design.

Regards,

Nick

Hi Ankur,

The design was tested with 2 1km fiber cables. Sampling and averaging capabilities are described in section 2.4:
