2.
Take common 4+1 and 8+1 wavelengths for example. The major performance indices
of the ZXMP M600 OMD units are as shown in Table 2.8-1.
Parameter
Bandwidth of CWDM channel @ 0.5dB
Insertion loss
(including the
connector)
Isolation
Return loss
Note 1: Please note that 2.3dB loss is intended for system requirement. The actual product performance is much better
than the requirement, up to 0.5dB can be reduced in OMD loss when calculating budget. Configuration can use typical
value of 2.0dB (4+1 Wavelengths) and 3.0dB (8+1 Wavelengths).

2.8.2 Performance Indices of OAD Units

The OAD units used in the ZXMP M600 system include OAD1, OAD2 and OAD3.
The figure in each unit indicates the number of add/drop channels.
The optical interfaces of the OAD units are shown in Fig. 2.8-2.
Here, A Line and A_ADi interfaces indicate the line optical interface and channel
optical interface at the A side respectively; B Line and B_ADi respectively indicate the
OMD5-1+OMD4-5: multiplexing/ demultiplexing 8+1 wavelengths. "+1"
indicates the 1310 channel.
