Quick Overview:
10Gtek's revolutionary 1 m QSFP to 4X SFP+ Splitter Cable offers IT professionals a cost-effective interconnect solution for merging 40G QSFP and 10G SFP+ enabled host adapters, switches and servers.

For typical applications, users can install this splitter cable between an available QSFP port on their 40-Gigabit/s rated switch and feed up to four upstream 10GbE-SFP+ enabled switches. Each QSFP-SFP+ splitter cable features a single QSFP connector (SFF-8436) rated for 40-Gb/s on one end and 4X SFP+ connectors (SFF-8431), each rated for 10-Gb/s, on the other.

Description:
10Gtek is the manufacturer of QSFP to 4 SFP+ Splitter Cables that designs and sources every subassembly in-house guaranteeing complete control over product performance, quality and consistency. EXamples include our widely respected board-as-connector platform which is direct-welded to the wire and encased in a robust Zinc-Nickel backshell for superior crosstalk and EMI performance. Cable available in 1m (3.3ft), 2m (6.6ft), 3m (9.8ft) & 5m (16.4ft) lengths to accommodate your installation requirements.
