    40G QSFP to 4xSFP+ breakout Active Optical Cable Specification

    40G QSFP to 4xSFP+ Compatible Active Optical Breakout Cable

    40G QSFP to 4xSFP+ Compatible Active Optical Breakout Cable, fully tested compatible for over 100 vendors.

    Description

    40G QSFP to 4xSFP+ active optical cable is a high-performance, low-power, long-distance interconnection solution that supports 40G.

    40G QSFP to 4xSFP+ is a combination of 4 full-duplex channels, each of which can transmit data at a rate of up to 10GB/s, providing an aggregation rate of 40GB/s.

    40G QSFP to 4xSFP+ active optical cable (AOC) can be used as an alternative to QSFP passive and active copper cables.

    Features 

    • Electrical interface compliant to QSFP+ connector

    (SFF-8436) and SFP+ connectors (SFF-8431)

    • Hot Pluggable
    • 850nm VCSEL transmitter, PIN photo-detector receiver
    • Operating case temperature: 0 to 70℃
    • 3V power supply voltage
    • All-metal housing for superior EMI performance

    Application:

    • 40 Gigabit Ethernet
    • Fibre Channel Applications
    • InfiniBand QDR, SDR, DDR
    • Servers, switches, storage and host card adapters
