Multiplexer
MXP2 EXAR

The MXP2 ASSP is a highly integrated, standards based device targeted at ROADM/DWDM and Edge Aggregation platforms in OTN transport applications. With flexible client ports supporting a wide range of protocols and frequencies, MXP2 enables development of any service-any port line cards and consolidation of a number of service specific muxponders (e.g. 10 x GE or 4 x OC-48/STM16) into a single, flexible, universal design.

MXP2 incorporates the latest changes to the G.709 standard including ODU0, ODUflex and GMP. This enables services (e.g. Gigabit Ethernet) to be mapped to size appropriate OTN containers and multiplexed in a single multiplexing stage (e.g. directly to ODU1 or directly to ODU2).

The dual SFI-4.1 network interfaces support protected line cards in ROADM/DWDM equipment. OTN ADM/ring functionality is supported with internal switching of ODU0/ODU1/ODU2/ODUflex containers. Similarly, SONET/SDH ADM/ring functionality is provided by internal STS-1/VC-4 switching.

The serial client interfaces may be connected directly to SFPs and operate over a wide range of frequencies to support many datacom, telecom and video protocols from 125 Mb/s to 4.25 Gb/s. While any signal regardless of protocol/format/encoding can be transported transparently and multiplexed with other signals, performance monitoring is provided for all recognized protocols (see Interfaces section for the list). A single SFI-4.1 client interface is available for higher rate client signals such as 8G FibreChannel and OC-192/STM-64.
