QSFP+ (quad small form-factor pluggable plus) cables offer a high density, high bandwidth, and cost-effective solution for a number of markets and applications. There are many kinds of QSFP+ cables. QSFP+ breakout cable is one of them. What is QSFP+ breakout cable? In this post, some basic information about QSFP+ breakout cables will be given.

To know whatQSFP+ breakout cableis, first you may ask what a breakout cable is. Breakout cable, or fanout cable, is an optical fiber cable containing several jacketed simplex optical fibers packaged together inside an outer jacket. Breakout cable is a hybrid solution. In a breakout cable, each fiber is individually reinforced, and each fiber is treated like a separate unit, so the cable can be easily divided into individual fiber lines. This design eliminates the necessity for a breakout kit, as the sheath allow you to attach connectors easily. It is different from distribution-style cable, in which tight-buffered fibers are bundled together, with only the outer cable jacket of the cable protecting them. The design of breakout-style cable adds strength for ruggedized drops than distribution-style cable. Breakout cable is suitable for short riser and plenum applications and for use in conduits.

A QSFP+ breakout cable consists of a QSFP+ transceiver on one end and four SFP+ transceivers on the other end. The cables are hot-removable and hot-insertable. QSFP+ transceiver connects directly into the QSFP+ access port on the QFX Series device. The cables use high-performance integrated duplex serial data links for bidirectional communication on four links simultaneously. And each SFP+ link is designed for data rates up to 10 Gbps. QSFP+ breakout cables create a great cost-effective interconnect way for IT professionals by giving much needed space for data centers and cost cuts.

There are many tyoes of QSFP+ breakout cable, here two commonly used kinds of them will be introduced, QSFP+ to 4SFP+ passive breakout copper cable and QSFP+ to 4SFP+ breakout active optical cable.

QSFP+ to 4 SFP+ passive breakout copper cable assemblies allow users to connect equipment with QSFP+ ports configured to work as four SFP+ ports. They offer a cost-effective, low-power option to support flexibility in high-speed data center applications. These high performance direct-attach assemblies support 4 lanes of 10 Gb/s (40Gb/s composite). These cables are the optimum solution for connecting your 40G QSFP+ and 10G SFP+ enabled host adapters, switches and servers without upgrading your entire data center or storage array.

QSFP+ to 4SFP+ breakout active optical 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. It is commonly used for storage, data, and high-performance computing interconnectivity. The following shows a CiscoQSFP-4SFP10G-CU3Mcompatible QSFP+ to 4SFP+ passive breakout copper cable and a Cisco QSFP-4X10G-AOC10M compatible QSFP+ to 4SFP+ active optical breakout cable.

QSFP+ breakout cables permit you to connect your QSFP+ and SFP+ switches and network cards without upgrading your entire data center or storage array. The cables provide inexpensive and low power consumption interconnect solution for 40 Gigabit Ethernet, Fibre Channel, QDR InfiniBand, 10 Gigabit applications and other industry standards.

Fiberstore provides QSFP+ to 4SFP+ passive copper breakout DAC, and QSFP+ to 4SFP+ breakout AOC. Custom cables can be found in various lengths along with other options. We currently provide several lengths to support your installation requirements. All our 40GBASE QSFP+ cables are 100% compatible with major brands like Cisco, Juniper and so on.
