OEM Silicon Photonics Technology 100G

100G silicon photonics technology enables high-speed, power-efficient optical communication for data centers and AI networks using integrated photonic circuits and PAM4 modulation.

Overview100

G silicon photonics (SiPh) integrates optical components on a silicon substrate, allowing compact, high-performance transceivers for Ethernet and data center applications. These modules typically use PAM4 signaling to double data throughput per lane and support single-lambda 100G transmission over single-mode fiber, with distances up to 500 meters for QSFP28 DR1 modules.

OE

Ms like Alpine Optoelectronics develop their own silicon photonics engines to produce 100G, 400G, and 800G transceivers.

Key Technical Features

Integration: Combines lasers, modulators, and photodetectors on a single silicon chip, reducing size and improving reliability. Modulation: Uses PAM4 (4-level pulse amplitude modulation) to achieve 100G per lane efficiently. Form Factors: Commonly deployed in QSFP28 pluggable modules for 100GBASE-DR Ethernet links.

Power Efficiency: Silicon photonics reduces heat generation compared to traditional optical modules, critical for high-density data centers. Scalability: Supports future upgrades to 200G per lane and beyond, leveraging advanced PICs (photonic integrated circuits) on 300 mm wafers.
