Industry’s First Terabit-scale Ethernet PHY Enables Highest-density 400 GbE and FlexE Connectivity
Microchip, via its Microsemi subsidiary, is the first to enable a unique set of capabilities with its META-DX1 family of Ethernet Physical-Layer (PHY) devices. The family enables telecom service providers to build out networks using routing and switching platforms that reduce costs, optimize bandwidth and increase capacity, security and flexibility.

Key Facts:
  • META-DX1 combines 100 GbE, 400 GbE and FlexE with nanosecond timestamping accuracy
  • Uniquely integrates MACsec security engine in a single chip with terabit capacity
  • Enables line cards to quadruple in capacity and meet 5G timing requirements
  • Flexible crosspoint switching simplifies the transition to 100 GbE and 400 GbE optics
 
Integrated into a single chip, the META-DX1 family combines Ethernet ports from 1 Gigabit Ethernet (GbE) to 400 GbE, Flexible Ethernet (FlexE), Media Access Control Security (MACsec) link encryption and nanosecond timestamping accuracy at terabit capacity.
 
The industry is transitioning from 100 Gigabit Ethernet (GbE) to 400 GbE to support traffic within hyperscale data centres. According to Cisco’s Global Cloud Index, this traffic will quadruple by 2021 with data centre-to-data centre traffic growing at more than a 30 percent Cumulative Annual Growth Rate (CAGR). The META-DX1 enables line cards to quadruple in capacity, from 3.6 terabits per second (Tbps) to 14.4 Tbps with 36 ports of 400 GbE or 144 ports of 100 GbE, while supporting key features needed by service providers.
 
The META-DX1 MACsec engine secures traffic leaving the data centre or enterprise premises. FlexE enables both cloud and telecom service providers to meet capacity requirements while reducing fibre-plant capital expenditures by optimally configuring links beyond today’s fixed-rate Ethernet so they can use low-cost, high-volume optics. The META-DX1 family uniquely combines MACsec and FlexE into one solution to meet the next phase of capacity scaling in Data Centre Interconnect (DCI) buildouts.
