## Summary description

The BlueOptics SFP28-DAC-3M-ZY is a 3-meter SFP28 DAC cable designed for high-speed data transmission. It features male connectors on both ends, ensuring a secure connection for networking applications. Ideal for connecting switches and servers in data centers, this cable offers reliable performance and durability.

## Long description

The BlueOptics SFP28-DAC-3M-ZY is a 3-meter direct attach copper (DAC) cable with SFP28 male connectors on both ends, designed for 25GbE and compatible high-speed networking environments. Its fixed-length construction provides a low-latency, low-power connection between switches, routers and servers in rack-mounted or top-of-rack installations. The cable's robust jacket and factory-terminated connectors ensure consistent electrical performance for short-reach data links in data centers and network closets.
Advantages
This SFP28 DAC cable delivers predictable signal integrity and minimal insertion loss for reliable 25 Gigabit connections. Being a passive, fixed-length copper assembly, it reduces the need for separate transceivers and lowers power consumption compared with optical modules. The male-to-male SFP28 terminations enable simple hot-pluggable installation into standard SFP28 ports, and the 3 m length balances flexibility with predictable channel characteristics for rack-to-rack or within-rack connections.
Suitable for
Short-reach 25GbE links between switches and servers
Top-of-rack and end-of-row networking in data centers
High-density switch interconnects where low latency is required
Test lab setups and temporary cabling for performance validation
Key specifications
Connector type: SFP28 male — both ends
Cable type: Direct attach copper (DAC)
Nominal length: 3 meters
Data rate: Designed for 25 Gigabit Ethernet applications
Construction: Factory-terminated assembly with durable outer jacket
Compatibility: Fits standard SFP28 ports supporting passive DAC modules
How to use
Power down equipment only if required by your operational procedures, then insert each SFP28 connector into the corresponding SFP28 port until the latch engages. Ensure the ports on both devices report link status and configure network interfaces according to your switch or server operating system. For cable management, route the assembly to avoid sharp bends and secure it with appropriate ties or panels to prevent strain on the connectors. If link does not establish, verify port configuration, compatibility, and physical seating of the connectors.
Usage recommendations
Use this 3 m DAC cable for short, high-performance connections in controlled data center environments. Avoid exposure to excessive mechanical stress, moisture, or temperatures outside typical equipment room ranges. For longer distances or fiber-based infrastructures, consider optical transceivers and fiber cabling instead of a DAC assembly.
