Microsemi announced mass production of its DIGI-G4, its latest DIGI Optical Transport Network (OTN) processor enabling the transition to 400G OTN switching solutions in metro transport networks.
Microsemi's DIGI-G4 enables network equipment vendors to double the 100G OTN port density on their optical transport systems, while achieving a 50 percent reduction in power per 100G port.
"We have been working very closely with some of the world's leading original equipment manufacturers to complete Carrier qualification of their 400G OTN designs," said Babak Samimi, vice president and business unit manager of Microsemi, Communications business unit. "This year we will see our DIGI-G4 deployed in networks worldwide as the key technology for driving the transition to 400G OTN switching, in addition to enabling a new wave of flexible optical transport infrastructure that is software-defined networking (SDN)-ready and delivers on the security needs being demanded for cloud-connectivity powered by our embedded encryption engine."
PMC-Sierra has commenced sampling of its new DIGI-G4 chip -- the industry's highest density 4x100G OTN processor and featuring 50 percent less power per port than the previous generation.
The DIGI-G4 OTN processor, which builds on the success of PMC’s DIGI-120G, enabling the transition to 400G line cards in packet optical transport platforms (P-OTP), ROADM/WDM and optimized data center interconnect platforms for OTN switched metro networks. It increases 10G, 40G and 100G line card port density by 4X with flexible client mapping of Ethernet, storage, IP/MPLS and SONET/SDH, while reducing power by 50 percent per port. DIGI-G4 builds on the IP from DIGI-120G, enabling customers to maintain their rich feature set and software investment, which reduces time to market by up to six months and lowers development costs.
Significantly, DIGI-G4 delivers multi-rate, sub-180ns latency OTN encryption, allowing cloud and communications service providers to ensure security without compromising performance. DIGI-G4 supports sub-wavelength OTN encryption and is compatible with OTN switched networks. PMC said these these capabilities, combined with the densest 10G/40G/100G Ethernet ports, enables a new class of low-power, high-capacity transport platforms optimized specifically for the hyperscale data center WAN interconnect market (see whitepaper).
