What is 800G OSFP SR8？

 The 800G OSFP SR8 optical transceiver module is a hot-swappable optical transceiver module designed for use in data center 800G SR8 Ethernet links. This module uses the latest 100G PAM4 and VCSEL technology to achieve 800G data interconnection within 100m. The emergence of this module enables data centers to achieve more efficient and reliable data transmission when performing high-speed data transmission.

100G PAM4 technology
100G PAM4 technology is a modulation technology that transmits data in the form of pulses. Compared with traditional binary signals, PAM4 signals have higher frequency band utilization and therefore can achieve higher data transmission rates. In the 800G OSFP SR8 optical transceiver module, PAM4 technology is used to achieve 800G high-speed data transmission.

VCSEL technology
VCSEL is a vertical cavity surface emitting laser. It is a laser manufactured on a semiconductor chip, and its emission direction is perpendicular to the surface of the semiconductor chip. VCSEL has the advantages of low power consumption, low cost, and high reliability, so it is widely used in the communication field. In the 800G OSFP SR8 optical transceiver module, VCSEL is used as the emitting light source to transmit data to the destination through optical fiber.
