Planning 2+ 0 links

Network configurations for 2+0
In a 2+0 configuration, Link ‘A’ and Link ‘B’ are independent. Each CMU is connected to
the network using one of the methods described in
Network configurations for 1+0
. The two links may be managed in different ways, for example Link ‘A’ may be
out-of-band and Link ‘B’ may be in-band.
Frequency spacing in 2+0 ODU based links
For co-polar deployments, the transmit frequency of link A and link B at a given end must
be separated by at least two channel separations. For example, if the channel separation is
configured as 28 MHz, the spacing between the two transmit frequencies must be at least
56 MHz.
For cross-polar deployments, the transmit frequency of link A and link B at a given end
must be separated by at least one channel separation. For example, if the channel
separation is configured as 28 MHz, the spacing between the two transmit frequencies
must be at least 28 MHz.
Frequency spacing in 2+0 IRFU based links
In a 2+0 IRFU-based link, plan the four transmit frequencies to meet the following
requirements:
•
At each link end, the two transmit frequencies must be separated by at least the
amount quoted in
•
At each link end, the transmit and receive frequencies must be separated by at least
the amount quoted in
