Our take on the Lenovo 00YL636 3M SFP+ to SFP+ Active Optical Cable

The Lenovo 00YL636 is a 3-meter SFP+ to SFP+ active optical cable for 10GbE links. It uses fiber and powered transceivers at each end instead of copper, so it is thinner, lighter and immune to electrical interference over its run. It suits short 10G runs between switches, servers and storage in racks and adjacent cabinets. Against passive copper DACs it costs more and draws a little power, but it bends easily and carries 10G farther without signal loss.

Pros
  • Fiber build resists EMI and crosstalk
  • Thin, light and easy to route in tight racks
  • 3 m length covers adjacent racks and cabinets
  • Plugs into standard SFP+ ports, no separate modules
  • Lower loss over its run than passive copper
Cons
  • Costs more than a passive copper DAC of the same length
  • Active ends draw power and add heat
  • Not for longer runs; beyond this length use separate optics and fiber
  • Only works in SFP+ ports, not QSFP or 1G SFP-only slots

Questions and answers

What is an active optical cable used for?
It links two SFP+ ports over fiber for 10GbE. The transceivers are built into each end, so you plug it in like a cable instead of buying separate optics.
How is it different from a copper DAC?
A copper DAC carries the signal electrically and is cheaper at short lengths. This cable converts to light, so it is thinner, lighter and immune to electrical interference, at a higher cost and with a little power draw.
Does it work in any SFP+ port?
It needs SFP+ ports rated for 10G, such as on Lenovo and other data center switches and network cards. It will not work in QSFP ports or in slots limited to 1G SFP.
What is in the box?
One 3-meter SFP+ to SFP+ active optical cable. No separate transceivers or power supplies are needed.
Is 3 meters enough for my setup?
It covers links within and between adjacent racks. For longer runs, plan on separate SFP+ optics with a fiber patch cable instead.
