Active Optical Cable Assembly for QSFP+ to SFP+ Applications Now Available
—First-to-market fanout cable assembly enables direct-attach connections
between 40GbE switch ports and 10GbE server ports in top-of-rack applications—
AUSTIN, Texas -- August 20, 2013
A fiber fanout cable assembly supporting the interoperability of 40 Gigabit
Ethernet (40 GbE) switch ports and 10 GbE server ports is now available from
the 3M Electronic Solutions Division. The first-of-its-kind, 3M Active Optical
Cable (AOC) Assembly for QSFP+ to SFP+ Applications incorporates
industry-leading VCSEL and 3M light-engine technologies to deliver exceptional
cost and performance value for data centers and high-performance computing
The hybrid AOC assembly transitions a single QSFP+ port with four parallel
channels to four individual, single-channel SFP+ ports in top-of-rack (ToR)
applications and at distances up to 100 meters. The fanout cable assembly
addresses a common data center and HPC problem in which QSFP+ switch ports are
under-utilized. Because the 3M fanout assembly allows direct-attach
transitions at a one-to-four QSFP+ to SFP+ ratio, more 40 GbE uplinks can be
“This new AOC fanout assembly from 3M helps simplify cable routing for 10 GbE
aggregation and 40 GbE top-of-rack applications while allowing optimization of
the limited QSFP+ uplinks found on today’s network switches,” said Jeff
Bullion, marketing manager, System and Components Business, 3M Electronic
Solutions Division. “It provides a true plug-and-play, low-cost, low-power and
low-latency alternative to the pluggable modules and patch cords commonly used
With no optical splices, the AOC Assembly for QSFP+ to SFP+ Applications from
3M provides seamless, end-to-end connectivity over bend-insensitive, multimode
fiber. The number of connections is cut in half compared to traditional module
solutions. Fewer connection points can improve reliability, reduce optical
loss and latency, and lower power consumption.
The cable assembly supports cost efficiency in a number of ways. Each of the
cable assembly’s parallel channels is synchronized to provide interoperability
between the 40 GbE and 10 GbE interfaces, which limits the amount of optical
debugging and tuning required, which can speed up installation. The
lightweight, thin fiber assembly makes cable routing and dress-out easier
while allowing better air flow in the rack, potentially reducing cooling
costs. In addition, one product replaces three (two types of transceivers and
a fiber cable), lowering cost and reducing purchasing and inventory management
The cable assembly is available in lengths up to 100 meters with the
individual and uniform fanout lengths ranging from 1 meter to 2.5 meters. It
is designed to meet SFF-8436, -8431, -8472 and -8432 standards. All 3M Active
Optical products meet FCC Class B and CE Emissions and Immunity requirements,
CDRH/IEC 60825-1 and are *RoHS 2011/65/EU compliant. Learn more about 3M
Active Optical products.
