• Clusters
• Servers
• Storage devices
Supporting multiple data transfer protocols:
• Infiniband – 4x SDR/DDR
• SONET/SDH – OC-12/OC-48
• 10 Gigabit Ethernet / 4 x 3.125 Gb/s
• Quad Fibre Channel (1/2/4 Gb/s)
• PCI Express 4x
The interconnect system comprises a 38 position 0.8mm pitch connector and a
press-fit cage designed to comply with the Quad Small Form-factor Pluggable
(QSFP) Transceiver Specifications.
The connector system is capable of data rates beyond 5 Gigabits per channel
(4 channels) and is intended for external connections (38 position connector).
