Quad Small Form- factor Pluggable (QSFP) Products
DESCRIPTION
Tyco Electronics is a leading developer of
Quad Small Form-factor Pluggable, a new
high speed pluggable I/O interface products.
This interconnect system offers 4 channels,
providing 3 times the density of SFP/SFP+
ports. QSFP cages and connectors are
designed for data rates up to 10 Gb/s,
supporting Fibre Channel, Ethernet,
SDH/SONET and INFINIBAND standards.
The cage/connector system will accept opti-
cal or copper interfaces.

PRODUCT APPLICATION
Components of a Quad Small Form-factor Pluggable
DESCRIPTION
The QSFP application
consists of:
• a 38-position high speed
surface mount connector for
the host board
• a cage which provides EMI
containment and guidance for
the mating plug
• a mating plug, which may be
in the form of:
•
•
•
a pluggable transceiver, which
accepts an MPO optical cable
a direct-attach QSFP copper
cable assembly
a direct-attach PARALIGHT
active optical cable
•
Cage accessories include
heatsinks, lightpipes, and
EMI/dust plugs.
