X24: 24x10G/40G/100G OTN & MACsec

The X12/X240 products integrate 100G Gearbox functionality with Ethernet PHY and OTN framer, delivering a cost and power optimized small foot print solution. The X120/X240 are ideal for high capacity Carrier Ethernet router/switches, Packet Optical Transport systems and DWDM Transport systems. Its integrated, high performance SerDes interfaces seamlessly with optical modules and direct attach copper cables. The X120/X240’s rich suite of Carrier Ethernet features, OTN mapping modes and provisional FEC ensure interoperability among multiple system OEMs. Highly integrated, low power 120 Gbps or 240 Gbps Smart PHY OTN processor device that supports up to 24-port 10G, 6-port 40G, or 2-port 100G Ethernet over OTN with MACsec, integrated Gearbox and 25G/28G CAUI-4/OTL4.4 interfaces.
