Overview

A photonic integrated device (PID) board integrates an optical transponder unit (OTU) and an optical multiplexer/demultiplexer (MUX/DEMUX) unit. One group of PID boards implement the same functions as multiple OTU and MUX/DEMUX units do.

The OptiX OSN 6800A uses the one PTQX board and one or two ELQX board to implement the PID function.

PID Implemented Based on PTQX and ELQX Boards

Figure 1 shows the details. One PTQX board and two ELQX boards form a 12-channel PID group and one PTQX board and one ELQX board form an 8-channel PID group. The ELQX board converts four 10GE LAN, 10GE WAN, STM-64, OC-192, OTU2 or OTU2e signals into four OTU2/OTU2e electrical signals or converts four ODU2/ODU2e signals or 16 ODU1 signals from the backplane into four OTU2/OTU2e signals. The PTQX board can map four 10GE LAN/10GE WAN/STM-64/OC-192/OTU2/OTU2e signals into four OTU2(e) signals, or map four ODU2(e) signals or 16 ODU1 signals from another board into four OTU2(e) signals. The PTQX also receives eight OTU2(e) signals from the ELQX board and integrates the 8 or 12 OTU2(e) signals into one channel of optical signals for output.

ODU1, ODU2, or ODU2e signals between PID groups can be scheduled by cross-connection boards.

As shown in Figure 2, three PID groups can be installed in OptiX OSN 6800A subrack and the three PID groups respectively occupy the following slots: IU1-IU4, IU5-IU8 and IU11-IU14.
Figure 2 Slots occupied by PID groups in an OptiX OSN 6800A subrack

NOTE:

On a subrack, slots 1, 4, 11, and 14 each supports a 40 Gbit/s capacity and other slots each supports a 20 Gbit/s capacity. That is, the first and third PID groups support a maximum of 120 Gbit/s capacity and the second PID group supports a maximum of 80 Gbit/s capacity.

PID Implemented Based on one NPO2(STND)/NPO2E Board

As shown in Figure 3, one NPO2(STND)/NPO2E board forms a 8-channel PID group. The NPO2(STND)/NPO2E board converts 64 channels of ODU0 signals, 32 channels of ODU1 signals, or 8 channels of ODU2/ODU2e signals into 8 channels of standard WDM wavelength OTU2/OTU2e signals.
NOTE:

An NPO2(STND)/NPO2E board without a PQ2 service processing board can form only a 4-channel PID group and carry 40G or lower rate services.
