The lower portion of the ONS 15252 MCU is referred to as the passive optical shelf. The passive optical shelf has an A side and B side. The A side of the ONS 15252 MCU is located on the left side of the passive optical shelf, as seen from the front. The A-side LM contains one line IN port (FC), one line OUT port (FC), and two line-monitoring ports (SC). The line-monitoring ports make it possible to monitor the A-side incoming and outgoing DWDM optical signals.

The B side of the ONS 15252 MCU is located on the right side of the passive optical shelf, as seen from the front. The B-side LM contains one line IN port (FC), one line OUT port (FC), and two line-monitoring ports (SC). The line-monitoring ports make it possible to monitor the B-side incoming and outgoing DWDM optical signals. The passive optical shelf also contains the A-side and B-side HFMs and TMs, BMs, CMXs, or CMYs in various combinations. Figure 3-5shows the typical arrangement of the modules.
