56G PAM4 VCSEL Array – Dual Top Contact

II-VI’s high speed 850 nm multimode VCSEL array is designed to meet stringent specifications for high speed data communications. The high performance, high reliability device is engineered with low electrical parasitics for data rates up to 28 Gb/s NRZ or 56 Gb/s PAM4. The VCSEL operates in multiple transverse and single longitudinal modes and emits a circular symmetric beam with low divergence that can be efficiently coupled into 50/125 and 62.5/125µm multimode fibers. The common cathode chip is available in 8 channel configuration with a pitch of 250 microns between individual channels.
