II‐VI Incorporated, a global manufacturer of optical components for datacom transmission, today introduced its 56 Gbps PAM4 VCSEL arrays for 400 gigabit Ethernet (GbE) short reach transceivers and active optical cables (AOCs) deployed in datacentres.

The availability of Ethernet equipment with greater than 12 Tb/s of switching capacity enables hyperscale datacenters to accelerate the migration from 100 to 400 GbE transmission.  II-VI’s 8-element VCSEL arrays can be modulated at 56 Gbps using 4-level pulse amplitude modulation (PAM4) to achieve a combined 400 Gbps over short reach multimode links.

“Customers come to II-VI because of our ability to deliver differentiated VCSEL technology without ever compromising on reliability,” says Karlheinz Gulden, General Manager, II-VI Laser Enterprise. “Our new 56 Gbps PAM4 VCSEL arrays represent the leading edge in VCSEL technology for AOCs and transceivers, which are in high demand in datacentres for server to server connectivity.”

AOCs and transceivers based on VCSELs offer the most cost-effective solution for datacenter links that span from 10 to 300 meters. They enable new applications in consumer electronics to connect ultrathin HDTV screens to remotely located driver electronics. The demand for VCSELs is expected to accelerate, driven by a growing number of 3D sensing applications in automotive and consumer electronics.
