## Long description

This CBO SFP28 Direct Attach Copper (DAC) Passive Twinax Cable 2 m is a 2‑metre twinax assembly designed for use with SFP28 ports. It provides a short‑reach, low‑latency electrical connection for 25 Gigabit Ethernet links between switches, servers and network interface cards without the need for separate optical transceivers. The passive construction requires no external power and is intended for rack‑level interconnects where cost efficiency and dependable performance are required.
Advantages
The passive twinax cable delivers low latency and consistent electrical performance suitable for high‑density rack environments. As a direct attach solution, it reduces per‑port cost by eliminating separate transceivers and simplifies deployment through plug‑and‑play connectivity. Its fixed 2 m length supports standard rack and cabinet layouts while the SFP28 form‑factor ensures compatibility with equipment that accepts SFP28 electrical interfaces.
Suitable for
 25GbE short‑reach connections between switches
 Server to top‑of‑rack switch links
 Direct connections to SFP28 NIC ports
 High‑density rack interconnects where low latency is required
Key specifications
 Connector type: SFP28 electrical direct attach
 Cable type: Passive twinax copper
 Nominal data rate: 25 Gigabit Ethernet
 Length: 2 metres
 Latency: low, suitable for short‑reach applications
 Power: passive design, no external power required
 Typical use: rack‑level interconnects and short links
How to use
Install the cable by inserting each SFP28 plug into the SFP28 ports of the two devices to be connected until the latch engages. Ensure both ends are fully seated and compatible with the host equipment's SFP28 electrical interface. No additional configuration or power source is required for the passive cable itself; any link configuration (speed, auto‑negotiation) is managed by the connected devices. For reliable operation, route the cable to avoid tight bends and mechanical strain on the connectors.
Usage recommendations
For best performance, use this 2 m passive DAC for short‑reach 25GbE connections within the same rack or adjacent racks. Verify device compatibility with SFP28 electrical direct attach modules and avoid exceeding recommended bend radii. If longer reach or optical isolation is needed, consider active DACs or optical transceiver solutions.
