Introduction of QSFP+ PSM4 Active Optical Cables
Industry-leading PSM4 (Parallel Single Mode Quad) Active Optical Cables (AOCs) achieve 40 to 56 Gbps data rates over long reaches up to 4 km, using a fraction of the power of other brands while providing streamlined installation for high-performance computing and storage applications.
The PSM4 AOCs use a Silicon Photonics (SiPh) optical engine and use lower cost singlemode fiber for transmission distances up to 4km. Pigtail versions (one end is a standard MTP/MPO connector) allow for easy plug-in to structured cabling, thus avoiding the need to pull the AOC through long distances of cable duct work. The low-power PSM4 AOC integrated cable solutions provide less expensive, reliable transport for aggregated data rates (from 40 to 56 Gbps) across much longer distances (4km) than VCSEL based AOCs.
QSFP+ PSM4 AOCs offer significant cost advantages over traditional optical transceiver modules and can easily be substituted by interfacing to systems via a standard QSFP+ MSA connector. The cables are electrically compliant with the QSFP+ interface InfiniBand FDR/DDR/QDR (Fourteen Date Rate / Double Date Rate / Quad Date Rate), Ethernet (10 and 40 Gbps), Fibre Channel (8 and 10 Gbps), SAS 3.0 and 2.1 (12 and 6 Gbps) and other protocol applications.
There are mainly three types of QSFP+ PSM4 AOCs shown as below:
QSFP+ 56 Gbps FDR PSM4 AOC |
QSFP+ to QSFP+ QDR PSM4 AOC |
QSFP+ to MPO Connector QDR PSM4 AOC |
Features & Benefits of QSFP+ PSM4 AOC
Advantages of Siph-based PSM4 Solution for 4-km Reach
Multiple forces are driving the implementation of PSM4 and SiPh in next generation data-center designs and architectures. PSM4 and SiPh fill an important gap in data-center interconnect options, the gap between the reach of 25G multimode options and that of Long Range (LR) optical approaches. Using pigtail designs with these technologies can ease implementation via easy mating to structured cabling. From a futureproofing perspective, PSM4 is an approach that can accommodate both current and future bandwidth upgrades. A SiPh-based PSM4 approach helps resolve the multiple challenges of higher bandwidth, longer distances, low power, and futureproofing. SiPh-based LR PSM4 products offer seven primary advantages.
SM SiPh bridges the gaps caused by the dual requirements of longer distances and higher data transmission speeds. With a broad base of products both available and being developed by multiple suppliers, PSM4 and SiPh AOCs can be deployed today to enable new data-center architectures, with the assurance that they'll provide a path to cost-effectively meet future upgrade requirements.
