Introduction to QSFP+ Active Optical Cable

QSFP active optical cable (AOC) is a high performance, low power consumption, long reach interconnect solution supporting 40G Ethernet, fiber channel and PCIE. It is widely used in many fields as well as promoting the traditional data center to step into optical interconnection. A brief introduction to QSFP+ active optical cable is given in this post.

What Is QSFP+ Active Optical Cable?

Active optical cable uses electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces. It is commonly used for short-range multi-lane data communication and interconnect applications, for it provides light weight, high performance, low power consumption, low interconnection loss, EMI immunity and flexibility. Active optical cable provides optimum link performance, high reliability, inter-operability and ease of installation. QSFP+ AOC is a high performance integrated cable for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 40Gbps aggregate bandwidth. Each lane can operate at 10Gbps with lengths ranging from one to 100m. QSFP AOC supports InfiniBand QDR/DDR/SDR, Ethernet (10 and 40Gbps), Fibre Channel (8 and 10 Gbps), SAS and other protocol applications. It is compliant with the QSFP MSA and IEEE P802.3ba. High-density QSFP interface provides a compliant connection meeting QSFP+ Multi-Source Agreement (MSA) requirements. And hot-pluggable transceiver allows insertion and removal of devices without powering down the system.

QSFP+ to QSFP+ Active Optical Cable

QSFP+ to QSFP+ active optical cable is a 40Gb/s parallel active optical cable which transmits error-free parallel 4×10Gb/s data over multi-mode fiber (MMF) ribbon cables. QSFP+ to QSFP+ AOC assemblies provide 4 fully duplex channels per cable supporting signal transmission rates up to 10Gb/s & 14Gb/s per channel. QSFP+ to QSFP+ active optical cables are permanently attached to the fiber, with no air gaps, providing protection from environmental contaminants and other user disturbances during installation. The QSFP+ to QSFP+ active optical cable interface is based on the SFF-8436 industry standard, while also meeting the requirements of the 40GBASE-SR4 Ethernet and Infiniband SDR, DDR, QDR & FDR standards.

QSFP+ to 4SFP+ Active Optical Cable

QSFP to 4 SFP+ active optical (breakout) cable is a 4×10Gb/s parallel active optical cable which transmits four separate streams of 10Gb/s data over ribbon cables in a point-to-multipoint configuration. The cable contains a QSFP+ module on one end and four separate SFP+ modules at the other ends. Based on proven VCSEL array technology and designed with MSA-compliant QSFP+ and SFP+ high-density connectors, these cables are compact, lightweight, and low power. QSFP+ to 4SFP+ active optical cable is ideally suited for high-density 10G Ethernet, InfiniBand QDR, and other datacom and high-performance computing applications.
