General Description

This product is a high data rate parallel active optical cable designed to overcome the bandwidth limitations of traditional copper cables. It provides 4 independent data transmission channels and 4 data receiving channels over multimode ribbon fiber, with each channel capable of 25 Gbps operation.

This enables an aggregate data rate of up to 100 Gbps over distances of up to 100 m, supporting ultra fast computing and data exchange applications.

The product is designed in accordance with the QSFP Multi Source Agreement, including form factor and optical and electrical interfaces. It is engineered to perform reliably under demanding environmental conditions such as temperature variation, humidity, and electromagnetic interference.

Functional Description

The module converts parallel electrical input signals into optical signals using a VCSEL array. These optical signals are transmitted through ribbon fiber and received by a photodiode array, where they are converted back into electrical output signals.

Each end of the cable contains 8 ports, with 4 dedicated to data transmission and 4 for data reception, enabling full duplex 100 Gbps communication.

The module operates on a single 3.3 V power supply, with internal connections for transmit and receive power. It supports a 2 wire serial interface for communication and control, allowing access to the QSFP memory map and module diagnostics.

Control and management pins include:

• ModSelL for module selection on shared interfaces

• SCL and SDA for serial communication

• ResetL for module reset functionality

• LPMode for power management

• ModPrsL to indicate module presence

• IntL for interrupt signaling and status alerts

The module automatically initializes on power up or insertion and signals readiness through the interrupt mechanism. It is designed to ensure stable operation, efficient power usage, and seamless integration into high speed networking systems.
