The TPO124 is a cost-efficient OTU2 muxponder. On the client side it has 8 SoftPorts, i.e. serial ports that can be configured to any protocol, any rate between 0.1 and 4Gbps. TPO124 supports both the standard G.709 ODU0/ODU1/ODUflex mappings as well as proprietary mappings into 155Mbps timeslots that allows for even more efficient bandwidth utilization. On the line side TPO124 has an OTU2 port.
TPO124 offers connectivity at ODU0, ODU1 and 155Mbps timeslot level. A mate interface allows two TPO124s to be connected together to generate an add/drop multiplexer with 16 client ports and 2 (OTU2) line ports with full (40Gbps) ODUk connectivity between all ports.
