2.2.9 2-channel Transponder Card (O2M2-P)
O2M2-P is used to map 2 channels of multi-service 10G signals
(e.g.10GE/STM-64) to OTU2 signals, achieving transparent pass-through
of this traffic. Its NNI side supports 2 groups of 1+1 protections.
O2M2-P supports RMON function, alarm and performance monitoring
functions.
O2M2-P is coded by NRZ. It supports the ESC function to integrate the
monitoring information into the service channel for transmission.
O2M2-P has 4 NNI interfaces and 2 UNI interfaces. NNI/UNI optical
interfaces support the LC dual-fiber SFP+ optical module or single-fiber
SFP+ optical module. The front panel diagram is shown in Figure 2-15, the
LED is described in Table 2-19.
