Microsemi's DIGI-G5 powers Terabit OTN switching cards

Microsemi introduced its DIGI-G5 Optical Transport Network (OTN) processor for terabit capacity OTN switching cards.

The company said this newest generation in its DIGI franchise enables packet-optical transport platforms to triple in capacity while slashing power consumption by 50 percent per port.


DIGI-G5 delivers 1.2 terabits per second (Tbps) of combined OTN and client interfaces and is first to market with newly standardized 25 Gigabit Ethernet (GE), 50GE, 200GE, 400GE, Flexible OTN (FlexO) and Flexible Ethernet (FlexE) with integrated security engine enabling flexible encrypted optical connections.

Transporting Ethernet, storage, intellectual property (IP)/ multiprotocol label switching (MPLS) and 4G/5G Common Public Radio Interface (CPRI)/eCPRI services over 100G OTN switched connections has proven to be the most fiber, power and cost-efficient deployment solution for moving bits in today's metro and long-haul networks.

“Our DIGI OTN processor portfolio has been instrumental in transforming service provider networks to mass deploy 100G OTN switched networks,” said Babak Samimi, vice president and business unit manager for Microsemi's Communications Business Unit. “Our DIGI-G5 breaks new ground by enabling the industry’s transition to new OTN 3.0 architectures at terabit scalability by delivering three times the port density while lowering power consumption by 50 percent per port.”

DIGI-G5 highlights

  • Total interface bandwidth of up to 1.2Tbps
  • Comprehensive Ethernet support: 10GE, 25GE, 50GE, 100GE, 200GE, 400GE and the new OIF FlexE specification
  • New OTN 3.0 rates, enabling flexible (FlexO) and fractional 100G+ (OTUCn, OTUCn-m) transmission
  • 56G PAM-4 Serializer/Deserializer (SerDes) allows direct connection to QSFP-DD, OSFP and coherent digital signal processors (DSPs)
  • Integrated packet test set enables remote troubleshooting and debug, driving down capital and operating expenditures
  • Integrated security engine enabling end-to-end AES-256 based encryption and authentication
  • Integrated G.HAO bandwidth-on-demand processing for OTN switching networks
  • Innovative DIGI-Mesh-Connect architecture which enables compact, pay-as-you-grow OTN switching at lowest cost and power by eliminating the need for a centralized switch fabric device.
  • Sampling is expected in Q2
