What is the main AOC/DAC short-reach selection boundary?
DAC favors the shortest low-power links; AOC favors lighter and longer fixed short-reach links.
AOC / DAC Short-Reach Links
AOC and DAC Short-Reach Data Center Cabling
Plan short-reach data-center cabling with 10G–800G AOC, DAC and breakout cable directions by length, power, weight, bend radius, host mode and compatibility.
Delivery FAQ
Solution delivery questions
How does breakout differ from direct attach?
Breakout requires a supported source-port split mode and matching lower-rate endpoints.
Why is host signal capability important for DAC?
Passive copper loss and crosstalk depend on length, gauge and both host SerDes implementations.
What fields should an AOC/DAC RFQ include?
Provide both hosts and software, form factors, rate, direct or breakout mode, FEC, exact length, gauge or bend radius, route, quantity and acceptance requirements.
Core Capabilities
Core solution capabilities
01
Cable type assessment
Compare distance, power, weight, bend radius and serviceability.
02
Port and length matching
Confirm both form factors, lane modes and the exact routed length.
03
Dual-host validation
Validate EEPROM, FEC, errors and stability on both endpoints.
04
Rate and signal boundaries
Check lane count, gauge, host SerDes, FEC, breakout and port power from 10G to 800G.
Delivery Process
From requirements to delivery
1
Confirm both hosts
Collect both device, port and software versions.
2
Confirm routing and length
Define direct or breakout topology, bend radius and exact length.
3
Test the final assembly
Validate link-up, errors and stability at the ordered length.
