  • Product Overview

The Small Form-factor Pluggable Plus (hereafter referred to as QSFP+) solution is designed for high-density applications. The hot-pluggable transceiver integrates 4 transmitting and 4 receiving channels. These QSFP+ cable assemblies can replace four standard SFP+ cable assemblies. This results in higher port density, more cost effectiveness and reduce power budget as compared to standard SFP+ cable assemblies.

40G QSFP+ Direct Attach Cables , Various choices of wire gauge are available from 24 AWG, 26 AWG, 28 AWG and 30 AWG with various choices of cable length.
