Overview

40G QSFP+ to 4×LC Active Optical Cable (AOC) is a versatile, high-density solution designed to split a 40G QSFP+ port into four independent 10G channels via LC duplex connectors. Tailored for data centers, enterprise networks, and telecom environments, this AOC ensures efficient 40G-to-10G migration by seamlessly integrating with existing LC-based fiber infrastructure. It supports transmission distances of up to 100 meters using OM3/OM4 multimode fiber, delivering reliable, low-latency performance for high-speed applications like cloud services, storage systems, and network aggregation.

The cable combines plug-and-play simplicity with a lightweight, flexible design, eliminating the need for separate transceivers and reducing deployment costs. Its optical architecture ensures superior EMI resistance and lower power consumption compared to copper alternatives, while LC connectors enable easy integration with patch panels and high-density setups. Built for durability and scalability, this AOC offers a cost-effective, future-ready solution for optimizing 40G/10G network performance and connectivity flexibility.
