The damaged fiber optics connection in Nichols has recently been replaced. The issue was likely caused by mice chewing the cables.
The problem affected some teachers’ phones, but for the most part these issues did not affect students, as the school’s Internet traffic is wireless and does not go through the fiber optics cables.
“When they sent out the email, I went ‘Huh? The phones were broken?'” said Upper School science teacher Eric Nelson.
Two weeks ago, the school phones in Nichols Hall, which use the underground fiber optics cables to connect to the rest of the school and the outside world, started having intermittent issues. According to Director of Instructional Technology Dan Hudkins, after lengthy diagnostics, the school determined that one of the six pairs of fiber optics cables that go to Nichols had stopped working. As a temporary fix, the school changed the phones to use the other five pairs.
Within a few days, the phones started to have issues again, and it appeared as though another pair of cables had failed. According to Hudkins, the chances of two pairs of fiber optics cables, which usually have remarkable longevity, failing within days of each other is “astonishingly unlikely.”
The school called in an outside contractor for an evaluation. Since there was not any heavy construction that could have damaged or jostled the cables, the contractor concluded that the likely issue was mice that had found their way into the conduits and were chewing on the fiber optics.
Twelve armored pairs of cables have replaced the six pairs of fiber optics cables that run in underground conduits between Main Hall and Nichols. The conduits were sealed shut with foam, and rodenticide placed inside. As of the time of publication, the problem appears to be resolved.
“In the future, as we open other vaults for whatever maintenance reason, we’ll fill in the ends of the conduits, and we’ll put rodenticide in the vaults. We only did this [procedure] on the path we know would have the problem,” Hudkins said.
The school is not actively taking measures with the other conduits, but Hudkins has stated that if the administration encounters the same issue, they will most probably solve the problem in the same way, by sealing those cables with foam and applying rodenticide.
