Product Description

Product Overview

This 400GBASE - SR4 QSFP112 optical module is specifically designed to meet the high - speed connection requirements of modern data centers and high - performance computing environments. Aimed at short - distance application scenarios, it supports efficient data transmission in multimode fiber (MMF) networks.

Electrical Signal Input and Modulation:

The module employs a central wavelength of 850 nm, with the transmitting end integrating a Vertical - Cavity Surface - Emitting Laser (VCSEL) array and the receiving end adopting a PIN photodetector array. Four parallel channels each support a data rate of 106.25 Gbps, achieving a total bandwidth of 425 Gbps. The PAM4 modulation format doubles the data capacity per channel compared to the traditional NRZ modulation, optimizing bandwidth utilization. The MPO - 12/APC connector ensures secure and efficient connection with multimode fibers, supporting a maximum transmission distance of 50 meters over OM4 fibers. It is suitable for short - distance scenarios such as internal data center connections and high - speed interconnections between switches and servers.

The module integrates a Digital Diagnostics Monitoring (DDM) function to real - time monitor operational parameters such as temperature, voltage, and optical power, supporting preventive maintenance and enhancing network reliability. With a maximum power consumption design of 8.5 W, it balances energy efficiency, meeting the operation requirements of high - density network environments.
