DS125DF410: Device recommendation for optical application

Part Number: DS125DF410

Hello,

My customer is looking for suitable device for interface application between OLT and ONT in PON network.

Requirements is as follows:

   - GPON : Down 2.5Gbps / Up 1Gbps + burst mode, 10GPON : Down&Up 10Gbps

   - reshapiing, retiming, regenerating functions for optical communication

 Could you please review if the DS125DF410 can be used for the above application? Do you have a better solution?

Thank you.

  • Hi,

    The DS125DF410 is worth evaluating for this application. I'd recommend to order an evaluation board from TI.com product page and perform some initial evaluation. The caveat I would add is that TI did not formally validate DS125DF410 performance with burst mode data. Two guidelines below:

    • It would be assumed that data would implement some type of standard encoding (such as 64B/66B or 8B/10B)
    • The TI retimer has a max CDR lock time of 100ms. So long as the minimum data/non-data periods are longer than 100ms then I would expect the data flow to occur

    Cordially,
