"Bit Transparent Mapping (11.1 G)" and "Bit Transparent Mapping (10.7 G)" meet customer requirement for transparent bit transport of 10GE LAN signals. If a 10GE LAN signal is directly mapped into an OTU frame by means of bit transparent mapping, the 10GE LAN signal will overflow the OTU frame. Thus, to solve this problem, certain AFEC fields are occupied by the 10GE LAN signal. This is why the AFEC encoding gain is low and AFEC correction capability is comparatively poor for the signals in the AFEC field. In the "Bit Transparent Mapping (11.1 G)" mode, transmission of signals are achieved by increasing the OTU frame frequency. This ensures the encoding gain and correction capability of FEC. In this mode, however, the bit rate is higher than the standard bit rate of OTU2 signals.

It depends on custometer requirements Bit Transparent Mapping (11.1 G)" is used for transparent bit transport of 10GE LAN signals. It could use for ethernet services. If there is a variation of 10G data packet the "Bit Transparent Mapping (11.1 G) could be used as OTU frame size "Bit Transparent Mapping (11.1 G) is high and the data packets could be transparently transmitted if their lengths exceed Max. In our network, for 10G ethernet service from router, we use "B

In our network, for 10G ethernet service from router, we use "Bit Transparent Mapping (11.1 G)" to ensure complete transimission of 10GE ethernet service which contains synchronization information also can smoothly pass. "MAC Transparent Mapping (10.7G)" is used for transparent transmission of 10GE MAC frames as required by customers.It could use for SDH services. |
