    Have you been there long enough to have previously worked at one of the former RBOCs, and if so which? (I literally started by career at PacBell)

      No, I wish I would have had that badge of honor. I was only 16 when Bellsouth got bought by AT&T.

  • What's the split used on your PON deployment?

      1:12. Most of our deployments terminate in Corning OptiTap. We survey a street, get pole spacing (or handhole spacing) measurements, and submit an order for a custom cable with pigtails at those intervals to connect the terminal. We ran 4, 6, 8, and 12 port terminals, depending on what engineering specified for that job.

      We would use terminals with either 10 or 25 foot tails depending on how accurate the measurements were... lol either way the terminal had to make it from the port to the pole or handhole.

      Each PFP breaks out into 864 SC jacks - see below.

      Once they hit the CO, they terminate into an LGX shelf where theyโ€™re demuxed and you can test the individual ports from end-to-end.

      Thatโ€™s as far upstream as my job description allowed me to go :)

    Do you wire wrap all your cables

      All of the F1 copper cables entering the central office are terminated via wire wrap once they hit the frame, yes.

      I have not worked a job where we were adding capacity so I donโ€™t know if weโ€™d do this with new plant, but all existing is done this way and all repairs / change orders are re-terminated using a wire wrap gun.
