Xpic (With Mpt-Hc V2 And Mpt-Xp Only) - Alcatel-Lucent 9558HC User Manual

Functional description

XPIC (with MPT-HC V2 and MPT-XP only)

154
This solution is available with MPT-HC V2, MPT-XP, and 9558HC with the following
conditions:
• Repeater(s) inserted between two terminal MSS-4/8
• DATA exchange between the two MPR-e through an optical link only
• Synchronization configured in SyncE
• No XPIC configuration
• QoS policy aligned on the 4 stations
• Service: TDM2ETH, Ethernet traffic
The MPT-HC V2/MPT-XP supports Co-channel Dual Polarized (CCDP) operation using a
built-in Cross-polarized Interference Cancellation (XPIC) function. This function is
implemented by installing the RPS+XPIC external module. Two links are operated on the
same radio channel, with one using the vertical polarization and the other using the horizontal
polarization. XPIC typically provides a 20-dB improvement in polarization discrimination.
The actual improvement will depend on the native discrimination provided at antenna
alignment and any reduction of this discrimination caused by atmospheric effects (fading).
The XPIC can be implemented with or without the adaptive modulation.
The Radio configuration supported is co-channel XPIC.
