II-VI Incorporated Introduces 56 Gb/s PAM4 VCSEL Arrays for 400 Gigabit Ethernet Transmission

Feb 25, 2019

II‐VI Incorporated (Nasdaq:IIVI), a global leader in optical components for datacom transmission, today introduced its 56 Gb/s PAM4 VCSEL arrays for 400 gigabit Ethernet (GbE) short reach transceivers and active optical cables (AOCs) deployed in datacenters.

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 Gb/s using 4-level pulse amplitude modulation (PAM4) to achieve a combined 400 Gb/s over short reach multimode links. 

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

II-VI at OFC, Mar. 5-7, 2019, Booth #4312

Applications such as augmented reality, artificial intelligence and machine learning promise to be transformative across a broad range of industries. They are enabled by advanced technologies such as sensors that map their surroundings in three dimensions, communications networks that instantly ferry a vast amount of data across large distances and hyperscale datacenters that rapidly compile and analyze massive amounts of data. II-VI will showcase at OFC new products that enable the 5G optical infrastructure, hyperscale datacenters, 3D sensing and LiDAR to name a few. Stop by II-VI’s booth and discover what II-VI can do for you.
