Breakout cables from TIFNEX
Breakout cables let one switch port serve several servers or lower-speed switch ports, increasing density and reducing cost. TIFNEX supplies more than 700 copper and optical breakouts, including 800G OSFP to 2x400G or 4x200G, 400G QSFP-DD/OSFP to 4x100G, 200G to 2x100G, 100G QSFP28 to 4x25G SFP28 and 40G QSFP+ to 4x10G SFP+.
Many are coded for NVIDIA InfiniBand and Spectrum switches, plus Cisco, Arista, Juniper and Dell. Fiber breakout harnesses (MPO to LC) are in MTP/MPO trunks and jumpers.
Common questions
Does my switch support port breakout?
Most data center switches do, but it often needs to be enabled per port in the configuration. Send us the model and we will confirm.
Can I break out 400G to 4 x 100G with copper?
Yes, with a QSFP-DD or OSFP to 4x QSFP28 or QSFP56 DAC up to about 3m. For longer runs, use an AOC breakout or DR4 optics with MPO breakout fiber.
Are breakout cables used in GPU clusters?
Yes. 800G to 2x400G and 400G to 2x200G breakouts connect NVIDIA switches to ConnectX adapters in many AI clusters.
