Verizon Fiber Optic Cross Box

I ordered Verizon FiOS last week and this morning a Verizon technician came by an opened a gray box hanging from the pole outside my apartment. He was probably doing something in preparation for my FiOS install scheduled for next week. I was a bit surprised when he opened the box without a key, but maybe he had some type of RFID transmitter on him that unlocked the box some other way.

I've never seen fiber inside those boxes before so I grabbed my DSLR, put on the telephoto lens, and took some pictures from my window. The closest I could come to finding a name for these boxes is a "cross box". If anyone has more information on them, please leave a comment!
