## Summary description

The BlueOptics JNP-SFP-25G-DAC-0.5M-BL is a 0.5m SFP28 direct attach copper cable designed for high-speed data transmission. It features Male/Male connectors for easy connectivity and is ideal for connecting switches and servers in data centers. This cable ensures reliable performance and low latency for demanding applications.

## Long description

The BlueOptics JNP-SFP-25G-DAC-0.5M-BL is a 0.5 metre SFP28 direct attach copper (DAC) cable with Male to Male SFP28 connectors, designed for short-reach 25G connectivity in rack and adjacent-rack installations. It implements a passive 25GBase-CR twinax copper design with 30 AWG conductors and is MSA compliant for interoperability with hardware that supports SFP28 25GBase-CR DAC links. The cable is intended for reliable, low-latency electrical signal transmission between switches, servers, storage systems and other compatible data centre equipment over 0.5 m distance.
Advantages
This SFP28 DAC supports data rates up to 25 Gbit/s while providing low power consumption and minimal latency typical of passive twinax cables. MSA-compliant construction and use of high-quality components ensure broad compatibility with major vendor platforms and stable electrical performance. The short 0.5 m length reduces crosstalk and signal loss for direct rack-to-rack or in-rack connections and simplifies installation with plug-and-play SFP28 Male/Male interfaces.
Suitable for
Connecting switches to servers or storage within the same rack or adjacent racks
High-speed 25G Ethernet links in data centres and server rooms
FCoE, Fibre Channel or InfiniBand applications that support 25GBase-CR passive DACs
Environments where low latency and low power consumption are required
Key specifications
Interface: SFP28 Male to SFP28 Male
Length: 0.5 metre
Type: Passive twinax copper (DAC)
Data rate: up to 25 Gbit/s
Standard: 25GBase-CR, MSA compliant
Conductor gauge: 30 AWG
Typical power consumption: low (passive cable, ~0.1 W equivalent on link)
How to use
Insert each SFP28 connector into the corresponding SFP28 slot on the network devices to be linked, ensuring the modules are fully seated and latched. Verify that both connected devices support passive 25GBase-CR DAC links and that firmware or software settings do not block third-party DACs. After physical installation, check link status on the devices and configure network interfaces as required for 25G operation.
Usage recommendations
Use this 0.5 m DAC for short, direct connections inside racks or between adjacent racks only. Ensure compatible hardware platform support for 25GBase-CR passive twinax cables and keep firmware updated to maintain interoperability. Avoid tight bends and excessive strain on the cable; route it to prevent kinks and secure connectors to reduce movement during operation.
