## Summary description

CBO DAC Cable QSFP28 SC282801L1M30 1m is a 1‑metre passive Direct Attach Copper (DAC) cable with QSFP28 connectors. Designed for short‑reach high‑speed links in data centers and networking equipment, it provides a simple, low‑latency connection for 100GbE QSFP28 ports. Use cases include server-to-switch and switch-to-switch interconnects where cost-effective, reliable short-distance cabling is required.

## Long description

CBO DAC Cable QSFP28 SC282801L1M30 1m is a 1‑metre passive Direct Attach Copper (DAC) cable with QSFP28 connectors, intended for short‑reach, high‑speed connections in data center and networking environments. The cable supports 100 Gigabit Ethernet links between QSFP28 ports and provides a low‑latency, low‑power physical connection without the need for optical transceivers. Its fixed length and integrated connectors simplify installation and reduce component count in rack and switch topologies.
Advantages
The passive DAC design offers a cost‑efficient alternative to optical modules for short distances, eliminating the need for separate transceivers and fiber patching. As a copper direct attach solution, it delivers predictable latency and consistent signal integrity while consuming no additional power for active signal conversion. The one‑metre length minimizes cable slack in dense rack deployments and helps maintain tidy cable management in top‑of‑rack and end‑of‑row layouts.
Suitable for
Server-to-switch connections within the same rack or adjacent racks
Switch-to-switch uplinks in top‑of‑rack and spine/leaf architectures
Short‑reach 100GbE connections where passive copper is acceptable
Data center cabling where low latency and low cost per link are priorities
Key specifications
Connector type: QSFP28 to QSFP28 passive copper
Length: 1 metre
Data rate support: 100 Gigabit Ethernet (100GbE)
Passive direct attach copper design (no active electronics)
Typical use: short‑reach links inside racks or between adjacent racks
How to use
Install the cable by inserting each QSFP28 connector into the corresponding device port until it seats with a tactile click; ensure link LEDs or port indicators confirm a successful physical connection. Because this is a passive copper assembly, no additional configuration is required at the physical layer, though you should verify port settings and firmware compatibility on connected devices to ensure proper link negotiation at 100GbE. Route the cable to avoid sharp bends and secure it with existing cable management to prevent stress on the connectors.
Usage recommendations
Choose this 1‑metre passive DAC for short, cost‑sensitive interconnects where optical transceivers are unnecessary. Verify that both endpoints support QSFP28 passive copper links and confirm maximum supported cable length in the vendor documentation for each device. For longer distances or environments requiring electrical isolation, consider optical transceivers and fiber cabling instead.
