Is vendor compatibility and passive construction suitable for your setup?
⚡ At a Glance
- • Data Rate: Rated for full 10Gb/s over a 0.5 metre passive twinax connection
- • Best for: Short, high-density rack connections between SFP+ switches, NICs and NAS units
- • Not ideal for: Vendor-locked or explicitly incompatible switches, for example HP-ProCurve, HP-H3C, HP-Aruba, Arista, Mellanox and Dell Force10
Passive twinax SFP+ DAC cable, 0.5 metre long including connectors, uses AWG30 wiring and an I2C EEPROM for module identification. Delivers 10Gb/s across short rack runs and supports many major switch and NIC brands while excluding several vendor-specific models.
Consistent 10Gb/s throughput - thanks to 10Gb/s rating and twinax construction
Two-pair differential twinax copper, constructed with AWG30 wiring and a passive design, carries high-speed signals with minimal latency. An onboard I2C EEPROM reports module parameters to host ports for recognition.
Predictable full 10G performance for short links, suitable for switch-to-switch and server-to-NAS connections with low overhead and minimal signal conditioning.
Plug-and-play recognition - with I2C EEPROM for module identity
I2C EEPROM contains vendor and module information that SFP+ ports can read during link negotiation, aiding acceptance by compatible hardware. Passive electronics mean no active power draw from the cable itself.
Simplifies installation and reduces troubleshooting on compatible kit by allowing ports to identify the module quickly during boot and link-up.
Neat rack cabling and easy routing - with 0.5 metre AWG30 twinax
Short, fixed 0.5 metre length including SFP+ connectors and slim AWG30 construction produces minimal slack and good flexibility for tight port spacing. Passive copper construction keeps the assembly simple and robust.
Ideal for dense racks where short, tidy connections matter, helping maintain airflow and a clean patching layout.
