40G QSFP+ to 4xSFP+

The QSFP+ cable assemblies are high performance, cost effective I/O solutions for 40G LAN, HPC and SAN applications. QSFP+ copper modules allow hardware manufactures to achieve high port density, configurability and utilization at a very low cast and reduced power budget. The high speed cable assemblies meet and exceed Gigabit Ethernet , InfiniBand and Fibre Channel industry standard requirements for performance and reliability.


Sopto Copper QSFP+ and QSFP+ 40G cable products are offered in lengths up to 7m for an ultra-high performance, cost effective cable solution in 40-Gigabit speed applications including switched fabric I/O, switches, routers, data storage arrays, and high performance computer (HPC) clusters. The Quad Small Form-Factor Pluggable (QSFP) MSA interface supports a variety of communications standards including Fibre Channel, Gigabit Ethernet, SAS, InfiniBand and SONET.

QSFP+ (SFF-8436) to CX4 (SFF-8470) Cables

QSFP+ (SFF-8436) to CX4 (SFF-8470) cables use cutting edge technology to provide an excellent hybrid cable solution for CX4/InfiniBand and QSFP+ rated switches, network adapters, and storage arrays. These cables have a QSFP+ connector on one end and a CX4 Connector on the opposite end. Each QSFP+ to CX4 copper cable permits auto-negotiation between the two connected devices for optimal network throughput. Reaching data rates of up 5Gpbs per channel. Compatible with 4x Infiniband SDR/DDR and 10 GbE applications. 

QSFP+ (SFF-8436) to MIniSAS (SFF-8088) Hybrid Cable

QSFP+ (Quad Small Form-factor Pluggable) to MIniSAS (SFF-8088) hybrid cables are designed for high-density Serial Attached SCSI (SAS) applications. These cables are used as an interconnect solution between newer QSFP+ Hardware and older external 3G and 6G Mini SAS equipment and provide data transfer rates up to 10Gbops per channel at distances of up to 10 meters. These cables are compliant to QSFP+ Multi-Source Agreement. 

QSFP to 4x SFP+ Splitter Cable

QSFP to 4x SFP+ Splitter Cable offers IT professionals a cost-effective interconnect solution for merging 40G QSFP+ and 10G SFP+ enabled host adapters, switches and servers. For typical applications, users can install this splitter cable between an available QSFP+ port on their 40 Gigabit/s rated switch and feed up to four upstream 10GbE-SFP+ enabled switches.Each QSFP+ to SFP+ splitter cable features a single QSFP connector (SFF-8436) rated for 40Gb on one end and (4) SFP+ connectors (SFF-8431), each rated for 10Gb, on the other. SOPTO is the manufacturer of QSFP+ to 4 SFP+ Splitter Cables that designs and sources every subassembly in-house guaranteeing complete control over product performance, quality and consistency. Examples include our widely respected board-as-connector platform which is direct-welded to the wire and encased in a robust Zinc-Nickel backshell for superior crosstalk and EMI performance. 

QSFP+ Active Optical Cable (AOC)

The AOC offers 4 independent data transmission channels and 4 data receiving channels via the multimode ribbon fibers, each capable of 10Gbps operation. This product is a high data rate parallel active optical cable (AOC), to overcome the bandwidth limitation of traditional copper cable.Consequently, an aggregate data rate of 40Gbps over 100 meters transmission can be achieved by this product, to support the ultra-fast computing data exchange.
