Description
F-tone Networks QSFP+ to 8 x LC Connector Breakout Optical Cable are a high performance, low power consumption, long reach interconnect solution supporting 40G Ethernet, fiber channel and PCIe. It is compliant with the QSFP MSA and IEEE P802.3ba 40GBASE-SR4.
F-tone Networks QSFP+ Breakout Cable is an assembly of 4 full-duplex lanes, where each lane is capable of transmitting data at rates up to 10Gb/s, providing an aggregated rate of 40Gb/s.
QSFP+ Breakout Cable are suitable for short distances and offer a highly cost-effective way to connect within racks and across adjacent racks. These breakout cables connect to a 40G QSFP+ port of a switch on one end and to four 10G SFP+ Transceivers of a switch on the other end.
