TR-QC07L6-A002 40G QSFP+ Active Optical Cable (AOC

Detailed Product Overview

The 40G QSFP+ Active Optical Cable (AOC) is a factory-terminated, full-duplex cable assembly. It is designed to replace traditional copper direct attach cables (DACs) for longer reaches (typically 10 to 30 meters) while offering lighter weight, smaller bend radius, and superior EMI immunity. The assembly is compliant with the QSFP+ Multi-Source Agreement (MSA) SFF-8436 standard and supports the IEEE 802.3ba 40GBASE-SR4 protocol.

Key Technical Features

• Form Factor: Integrated QSFP+ to QSFP+ connectors at both ends.

• Data Rate: Supports a maximum aggregate data rate of 40 Gbps. This is achieved using four independent full-duplex channels, each operating at up to $10.3$ Gbps.

• Cable Type & Media: Utilizes Multi-Mode Fiber (MMF) (e.g., OM3 or OM4). Unlike passive DAC, the optical nature allows for longer transmission distances.

• Wavelength: The embedded transceivers operate at the 850 nm wavelength, employing VCSEL (Vertical Cavity Surface Emitting Laser) technology.

• Max Reach: Available in various lengths, commonly from 1 meter up to 30 meters.

• Low Power Consumption: An advantage over electrical cables for longer distances, typically consuming less than 1.5 W per end.

• Digital Diagnostics Monitoring (DDM): Supports DDM via an $\text{I}^2\text{C}$-based management interface for monitoring operating parameters like temperature and voltage.

• Applications: Ideal for high-capacity I/O in Storage Area Networks (SAN), Switched Fabric I/O in switches and routers, and connecting servers within a single rack or between adjacent racks.

• Breakout Option: Breakout AOCs are also available (e.g., QSFP+ to 4xSFP+) to connect a single 40G port to four 10G ports.
