QSFP interface meets need for speed
Quad small form-factor pluggable product offering is compatible with the QSFP multisource agreement and combines optimal real estate, power and port density.
Molex has introduced a quad small form-factor pluggable (QSFP) product offering as a part of a highly integrated system that is compatible with the QSFP multisource agreement (MSA) and combines optimal real estate, power and port density This latest product offering integrates four 10G high speed channels into a single pluggable interconnect system, resulting in three times the port density of SFP and lower cost per channel

The new DPS/MPS power connectors from Molex meet the Server System Infrastructure (SSI) open specifications for backplanes.
QSFP is the next-generation hot-pluggable interface for high performance switches, routers, servers and host bus adapters for computing and telecommunication applications.
QSFP is currently the world's most compact, four-high-speed-channel, z-axis pluggable interface.
The Molex QSFP interconnect system supports speeds of up to 10Gbit/s per lane and, with an optional serial management interface, the Molex copper QSFP cable assembly delivers the same performance as an optical solution but at a lower cost.

Compact transceiver suits three optical standards
The small-form-factor (SFF) LC 2.5Gbit transceiver from Molex Fibre Optics is available in three different versions to suit application requirements.
The offering includes the SMT host connector and an EMI shielding cage assembly, as well as passive and active cable assemblies.
"Molex is the first to offer a 40Gbit/s copper QSFP interconnect system".
says Jay Neer, Strategic Product Manager for Molex.
"The Molex system is designed to minimise our customers' design efforts surrounding cable management, signal integrity of the host connector module interface and EMI".
Using the same iPass connector as the x4 PCIe, the QSFP 38-circuit SMT host connector provides the density and headroom required to support four high-speed channels of up to 10Gbit/s each.
With a pitch of 0.80mm, the SMT host connector is designed for placement under an EMI cage that accepts both pluggable optical modules and copper cables.
The SMT host connector allows the circuit designer the option to place the connector on either side of the PCB.
Additional benefits include alignment posts to provide stability when placing the connector and standoffs to facilitate PCB cleaning.
The Molex QSFP EMI cage is offered as a one-piece, press-fit configuration that is designed for easy assembly and accepts either optical modules or copper cables.
The single host connector and cage combination supports a belly-to-belly configuration.
The Molex EMI cage bezel interface is available with either EMI spring fingers or a compression gasket.
heatsinks and light pipes are also available options.
Molex provides the total copper solution by offering both passive and active copper cable assemblies at datarates of up to 40Gbit/s.
Within rack applications, the Molex passive cable assemblies have the lowest cost per port in the market today.
Active cables of up to 20m in length enable longer-reach, rack-to-rack connections.
Additionally, the Molex QSFP cable assemblies feature zinc, die-cast backshells to provide enhanced EMI shielding.
They also support Ethernet, Fibre Channel, InfiniBand and Sonet/SDH.
"The QSFP specification provides the industry's highest bandwidth density in a standardised pluggable interface", says Scott Kipp, Chairman of the QSFP MSA.
"By providing the QSFP product offering that works at 10Gbit/s per channel or 40Gbit/s aggregate, Molex demonstrates its leadership in providing a solution that meets the industry's need for speed".
