Coherent Introduces 100G PAM4 VCSEL And Photodiode Arrays For 800G Transceivers And Active Optical Cables

摘要

Coherent Corp., a leader in datacom transceiver components, announced the introduction of its 100G PAM4 vertical-cavity surface-emitting laser (VCSEL) and photodiode (PD) arrays for 800G short-reach datacom pluggable transceivers and active optical cables (AOCs.) Cloud and Al service providers are ramping up deployments of short-reach 800G transceivers and AOCs for their megascale datacenter buildouts. Coherent introduced eight-element VCSEL arrays, where each VCSEL can be modulated at 100 Gbps using a four-level pulse amplitude modulation (PAM4) format. The eight-element arrays enable 800 Gbps transmission in short-reach transceivers and AOCs. The VCSEL arrays can be paired with Coherent's new 100 Gbps PAM4 high-speed PD arrays.
