3. Description

High Speed 40G QSFP+ to 4×10G SFP+ Direct Attach Cable copper cable assemblies are a low cost alternative for short reach 4X applications. They are designed to be fully compatible in form factor and optical/electrical connections according to the QSFP Multi-Source Agreement.

QSFP+ connectors provide four channels of data in one pluggable interface. Each channel is capable of transferring data at 10Gbps and supports a total of aggregate 40Gbps as specified for QSFP+. These interconnects have three times the density of SFP+ interconnects(MSA) and have been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

QSFP+ cable assemblies are hot swappable and the programmed EEPROM signature enables the host to differentiate between a copper cable assembly and a fiber optic module.

Low power consumption assists in making the passive copper cable assembly an economic solution for within rack, or rack-to-rack applications.

4. Standard

• Compliant with electrical standards IEEE 802.3ba
• Compliant with mechanical standard SFF-8436 and SFF-8431
• Compliant with EEPROM standard SFF-8472
• RoHS Compliant
