We didn’t remove the protective tube yet.

Conclusion• We only finished the 12 bundles installation. (since the

people who helped me install the fibers are employed temporarily, for now only one IHEP employee and I are installing the bundles. But that’s OK, since we don’t want to push it in a hurry.)

• The bottom box has been installed. We’ll try to finish the rest bundles in this weekend.

• Next Monday we’ll begin to install the EC TOF of east side.
