Hybrid QSFP+ to 4xSFP+ breakout cable

This passive copper assembly splits a single 40GbE QSFP+ port into four independent 10GbE SFP+ links over a 9.84 ft run. It targets data-centre operators who need to connect a 40GbE switch or adapter to multiple 10GbE servers or top-of-rack switches without deploying transceivers and patch cords.

Replaces active optics or transceiver pairs

The cable removes the cost, power draw and latency of two optical modules and a fibre jumper for short-reach links inside a rack or adjacent racks. The jump is worth it when the connection distance fits within the 3 m passive reach and the port density gain of four 10GbE links from one QSFP+ socket simplifies cabling.

Handles four 10GbE channels at full line rate

Each SFP+ leg delivers 10 Gbps compliant with SFF-8431 while the QSFP+ end aggregates 40 Gbps per SFF-8436. Headroom ends at the 3 m copper limit; longer runs or links requiring galvanic isolation need active optical or active copper alternatives.

Questions about this item

What rack spacing does the 3-metre hybrid cable require between the QSFP+ port and the four SFP+ ports?

The cable spans 3 metres (9.84 ft) end-to-end, so allow at least that much clear path between the single QSFP+ connector and the four SFP+ connectors without sharp bends.

Which orientation do the SFF-8436 QSFP+ and SFF-8431 SFP+ connectors need when inserting them?

Both connector types are keyed; align the notch on each plug with the port slot and press straight in until the latch clicks — forcing at an angle bends the internal copper conductors.

How can I tell when the passive copper assembly should be replaced?

Replace the cable if link errors appear on any of the four 10 GbE lanes, if the latch no longer holds the SFP+ modules firmly, or if the jacket shows kinks or exposed conductor.
