40G DAC Copper Cables

QSFP is short for quad (4-channel) small form-factor pluggable. These transceivers are used to connect switches and routers to the network. QSFP+ modules are hot-pluggable which allows them to be plugged into a QSFP+ port without shutting down the system. These direct attach cables are used to connect switches and routers to the network.

Hardware Standards & Compliance

Never Sourced. Never Recycled.

All components in GigaTech Product optics are manufactured under the same roof and represent the gold standard for reliability and consistency in performance. This vertical manufacture chain allows GigaTech to avoid unnecessary variances in transceiver casing or laser quality often found with online resellers who source their components from an ever changing vendor list. The transceiver is guaranteed to be built from A-Stock never used components overseen by GigaTech Products.

Meets or Exceeds All Quality Certification Standards

The quality and standards of our hardware is one the base foundations of GigaTech Products. All of our components comply with MSA (Multi-Source Agreement) output standards and, in many cases, excel beyond those certification standards. Every transceiver we produce is tested on active network devices to ensure they comply with OEM equipment and are verified to be plug-and-play and do not require work arounds.
