Hub Filter Module

5.12 Hub Filter Module

The HFM filters one wavelength from the incoming DWDM optical signal and transfers the remainder of the wavelengths to subsequent HFMs. The HFMs each add one wavelength to the outgoing DWDM optical signal. The HFM is located to the right of the Line module (LM) on the A side of the ONS 15252 MCU and to the left of the LM on the B side of the ONS 15252 MCU. The row of HFMs must end with either a BM, a TM, a CMX, or a CMY.

5.13 Line Module

The LM receives an incoming aggregate optical signal from the DWDM side of the ONS 15200 system and transfers the outgoing aggregate optical signal to the DWDM side of the ONS 15200 system. A pair of LMs, one for the A side and one for B side, reside in the passive optical shelf of the ONS 15252 MCU. The LM contains the monitoring ports for both the incoming and outgoing traffic streams. The split ratio of the monitoring ports is 10/90. The external interface on the LM can be either an SC or an FC optical connector.

5.14 Termination Module

Install a TM in the passive optical shelf of the ONS 15252 MCU after the you have installed the HFMs. Insert the TM to the right of the HFMs on the A-side of ONS 15252 MCU and to the left of the HFMs on the B-side of the ONS 15252 MCU in place of the BM. The TMs terminate the optical signal and improve crosstalk. The TMs can replace the BM when all traffic terminates at the ONS 15252 MCU.
