The combination of Innovium with Inphi, Marvell’s most recent $10 billion acquisition, will enable the company to co-package optics alongside the high-bandwidth, low-latency switch chips.

“Inphi has quite a bit of experience shipping silicon photonics with the ColorZ and ColorZ II [modules],” says Nariman Yousefi, executive vice president, automotive, coherent DSP and switch group at Marvell. “And we have programmes inside the company to do co-packaged optics as well.”

Cavium broadens its Xpliant switch-chip offerings

• Two families of Xpliant switch chips have been unveiled: the XP60 with sub-terabit switching capacities and the mid-range XP70 devices with 1 to 1.8 terabits of capacity.
• The switch ICs broaden the datacom and telecom markets Cavium can now address. 
• Cavium is developing a next-generation high-end switch chip but the company is not saying when it will be announced. 

Cavium has broadened its portfolio of switch chips. The two families - the XP60 and the XP70 - have smaller switch capacities than Cavium’s XP80 Xpliant family and feature architectural enhancements.

“The new chips expand Cavium’s addressable markets to include enterprise and carrier-access networks as well as mainstream cloud data centres,” says Bob Wheeler, principal analyst for networking at The Linley Group.

The switch chips enable Cavium to address 25-gigabit interface switches, power-constrained enclosure designs such as blade servers, and 5G cloud radio access networks (CRAN) and GPON aggregation.

Until now Cavium has offered three XP80 Xpliant switch ICs, the largest being a 3.2-terabits switch. In contrast, the three XP70 devices have switch capacities of 1, 1.4  and 1.8 terabits while the XP60’s three chips have 280, 560 and 720 gigabits of capacity.
