## Summary description

The BlueOptics EMC DAC-QSFP-100G-1M is a 1m DAC cable with QSFP28 connectors designed for high-speed data transmission in data centers. It offers reliable performance and low latency for InfiniBand and fibre optic applications.

## Long description

The BlueOptics EMC DAC-QSFP-100G-1M is a 1 metre direct-attach copper (DAC) cable with QSFP28 connectors, engineered for short-reach, high-bandwidth interconnects in data centre and high-performance computing environments. Designed for 100G links, this DAC cable provides a cost-effective, low-latency connection option for switches, routers, network interface cards and storage systems that accept QSFP28 transceivers. The compact, rugged construction and fixed length of 1 m simplify rack-to-rack or within-rack cabling while maintaining signal integrity and consistent throughput.
Advantages
This DAC cable delivers deterministic latency and stable performance for high-speed InfiniBand and Ethernet fabrics. Its fixed passive copper design eliminates the need for optical transceivers, reducing power consumption and total link cost. The QSFP28 connector form factor supports 100G data rates and backward compatibility with equipment that accepts QSFP-based interfaces. The black jacket and durable strain relief improve durability in dense cabling environments and help maintain reliable physical connections under normal rack conditions.
Suitable for
 Short-reach 100G connections between switches and routers within the same rack or adjacent racks
 High-performance computing clusters using InfiniBand or Ethernet fabrics
 Direct connections between network interface cards and top-of-rack switches
 Storage system interconnects requiring low latency and high throughput
Key specifications
 Connector type: QSFP28 to QSFP28
 Length: 1 metre
 Data rate: 100 Gbit/s
 Cable type: Direct-attach copper (DAC), passive
 Jacket colour: Black
 Typical use: Short-reach data centre interconnects
How to use
Before installation, verify that both endpoints support QSFP28 passive DAC connections and that ports are powered down or able to hot-plug per equipment guidance. Align each QSFP28 connector with the port and insert firmly until the latch engages; avoid excessive force and ensure the cable is not twisted. Route the cable to minimise sharp bends and mechanical stress, leaving adequate slack for maintenance access. After insertion, confirm link establishment via the host or switch management interface and monitor link status for expected speed and error rates.
Usage recommendations
Use this 1 m DAC cable for short-distance, high-bandwidth links where optical transceivers are not required. For reliable operation, maintain bend radii above manufacturer minimums, avoid extended exposure to elevated temperatures near hot exhausts, and inspect connectors for debris before mating. For longer runs or environments requiring electrical isolation, consider fibre optic options instead of direct-attach copper.
